Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and description of business	Organization and description of business Education Realty Trust, Inc. ("EdR" and collectively with its consolidated subsidiaries, the “Trust”) was organized in the state of Maryland on July 12, 2004 and commenced operations effective with the initial public offering that was completed on January 31, 2005. Through the Trust's controlling interest in both the sole general partner and the majority owning limited partner of Education Realty Operating Partnership L.P. ("EROP" and collectively with its consolidated subsidiaries, the "Operating Partnership"), the Trust is one of the largest developers, owners and managers of collegiate housing communities in the United States in terms of beds owned and under management. The Trust is a self-administered and self-managed REIT that is publicly traded on the New York Stock Exchange under the ticker symbol "EDR". Under the Articles of Incorporation, as amended, restated and supplemented, the Trust is authorized to issue up to 200 million shares of common stock and 50 million shares of preferred stock, each having a par value of $0.01 per share. The sole general partner of EROP is Education Realty OP GP, Inc. (“OP GP”), an entity that is wholly-owned by EdR. As of June 30, 2017 , OP GP held an ownership interest in EROP of less than 1% . The limited partners of EROP are Education Realty OP Limited Partner Trust, a wholly-owned subsidiary of EdR, and other limited partners consisting of current and former members of management. OP GP, as the sole general partner of EROP, has the responsibility and discretion in the management and control of EROP, and the limited partners of EROP, in such capacity, have no authority to transact business for, or participate in the management activities of EROP. Management operates the Trust and the Operating Partnership as one business. The management of the Trust consists of the same members as the management of the Operating Partnership. EdR consolidates the Operating Partnership for financial reporting purposes, and EdR does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the Trust and the Operating Partnership are the same on their respective financial statements. Unless otherwise indicated, the accompanying Notes to the Condensed Consolidated Financial Statements apply to both the Trust and the Operating Partnership. The Trust also provides real estate facility management, development and other advisory services through its taxable REIT subsidiaries ("TRS"), EDR Management Inc. (the “Management Company”), a Delaware corporation that performs collegiate housing management activities. EDR Development LLC (the “Development Company”), a Delaware limited liability company and wholly-owned subsidiary of the Management Company, which provides development consulting services for third-party collegiate housing communities, is a disregarded entity for federal income tax purposes and all assets owned and income earned by our Development Company are deemed to be owned and earned by our Management Company.

Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of significant accounting policies Basis of presentation The accompanying condensed consolidated financial statements have been prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States (“GAAP”). The accompanying condensed consolidated financial statements of the Trust represent the assets and liabilities and operating results of the Trust and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying condensed consolidated financial statements. Principles of consolidation The Trust evaluates its interest in partnerships, joint ventures and other similar entities under the variable interest entity (“VIE”) guidance. Under the VIE model, the Trust consolidates an entity when it has control to direct the activities of the VIE and where it is determined to be the primary beneficiary. If it is determined that the legal entity qualifies for a VIE scope exception or the legal entity is not subject to the VIE model, the voting interest model is applied. Under the voting interest model, the Trust consolidates an entity when it controls the entity through the ownership of a majority voting interest. All of the Trust's property ownership, development and related business operations are conducted through the Operating Partnership. See the assets and liabilities of the Operating Partnership in the accompanying condensed consolidated financial statements. Interim financial information The accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the Trust's financial position, results of operations and cash flows for such periods. Because of the seasonal nature of the business, the operating results and cash flows are not necessarily indicative of results that may be expected for any other interim periods or for the full fiscal year. These financial statements should be read in conjunction with the Trust's consolidated financial statements and related notes included in the Trust's Annual Report on Form 10-K for the year ended December 31, 2016 , as filed with the Securities and Exchange Commission (the "SEC") on February 28, 2017. Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Collegiate housing properties Land, land improvements, buildings and improvements, and furniture, fixtures and equipment are recorded at cost. Buildings and improvements are depreciated over 15 to 40 years, land improvements are depreciated over 15 years and furniture, fixtures and equipment are depreciated over 3 to 7 years. Depreciation is computed using the straight-line method for financial reporting purposes over the estimated useful life. The Trust capitalizes interest based on the weighted average interest cost of the total debt and internal development costs while developments are ongoing as assets under development. When the property opens, these costs, along with other direct costs of the development, are transferred into the applicable asset category and depreciation commences. Acquired collegiate housing communities’ results of operations are included in the Trust’s results of operations from the respective dates of acquisition. Appraisals, estimates of cash flows and other valuation techniques are used to allocate the purchase price of acquired property between land, land improvements, buildings and improvements, furniture, fixtures and equipment and identifiable intangibles, such as amounts related to in-place leases. Acquisition costs are expensed as incurred for acquisitions completed prior to the adoption of Accounting Standards Update ("ASU") 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business" ("ASU 2017-01") and are included in general and administrative expenses in the accompanying condensed consolidated statements of income and comprehensive income. The Trust adopted ASU 2017-01 prospectively on January 1, 2017. Acquisition costs have been capitalized for subsequent acquisitions that are not deemed to be business combinations. Management assesses impairment of long-lived assets to be held and used whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Management uses an estimate of future undiscounted cash flows of the related asset based on its intended use to determine whether the carrying value is recoverable. If the Trust determines that the carrying value of an asset is not recoverable, the fair value of the asset is estimated and an impairment loss is recorded to the extent the carrying value exceeds estimated fair value. Management estimates fair value using discounted cash flow models, market appraisals if available and other market participant data. During the six months ended June 30, 2017 and 2016 , there were no impairment losses recognized. When a collegiate housing community has met the criteria to be classified as held for sale, the fair value less cost to sell such asset is estimated. If the fair value less cost to sell the asset is less than the carrying amount of the asset, an impairment charge is recorded for the estimated loss. Depreciation expense is no longer recorded once a collegiate housing community has met the held for sale criteria. Dispositions that represent a strategic shift in the business will qualify for treatment as discontinued operations. The property disposition during the six months ended June 30, 2017 did not qualify for treatment as discontinued operations and, as a result, the operations of the property are included in continuing operations in the accompanying condensed consolidated statements of income and comprehensive income. During August 2016, the Trust committed and finalized plans to demolish and redevelop Players Club, an off-campus community that serves Florida State University. Depreciation estimates were revised to reflect the shortened remaining useful life. The Trust recorded $1.1 million and $2.9 million of accelerated depreciation during the three and six months ended June 30, 2017 , respectively, related to the change in estimate. The impact on net income attributable to EdR common stockholders per share - basic and diluted for the three and six months ended June 30, 2017 was $0.02 and $0.04 , respectively. The depreciable assets were fully depreciated and subsequently written off when demolition began in the second quarter of 2017. Redeemable noncontrolling interests (the Trust) / redeemable limited partners (EROP) The Trust follows the guidance issued by the Financial Accounting Standards Board ("FASB") regarding the classification and measurement of redeemable securities. The Trust classifies redeemable noncontrolling interests, which include redeemable interests in consolidated joint ventures with puts exercisable by the joint venture partners and units of limited partnership interest in University Towers Operating Partnership, LP and in the Operating Partnership in the mezzanine section of the accompanying condensed consolidated balance sheets. The Trust accounts for certain noncontrolling interests with embedded put and call features with fixed exercise prices and exercise dates as a financing arrangement, and these amounts are recorded as accrued liabilities in the accompanying condensed consolidated balance sheets. The liability is initially measured at present value of the fixed price settlement amount. Subsequently, the liability is accreted to the fixed price over the term of the contract, with the resulting expense recognized as interest expense. The Trust also has certain noncontrolling interests with put options at substantially fixed prices. These noncontrolling interests are accounted for as noncontrolling interests redeemable at other than fair value. The Trust accounts for the change in redemption value through the use of an accretion model from the date of inception to the expected redemption date. Changes in redemption value are recorded in equity, either through retained earnings or additional paid-in capital (absent any retained earnings). The impact of the changes in redemption value (accretion) is included in earnings per share using the two-class method. In the accompanying condensed consolidated balance sheets of the Operating Partnership, the redeemable units of limited partnership in the Operating Partnership are classified as redeemable limited partners, and the redeemable interests in consolidated joint ventures with puts exercisable by the joint venture partners and units of limited partnership interest in University Towers Operating Partnership, LP are classified as redeemable noncontrolling interests. The redeemable noncontrolling interests / redeemable limited partner units are adjusted to the greater of carrying value or fair market value based on the price per share of EdR's common stock or redemption value at the end of each respective reporting period. Common stock issuances and offering costs Specific incremental costs directly attributable to the issuance of EdR common stock are charged against the gross proceeds of the related issuance. Accordingly, underwriting commissions and other stock issuance costs are reflected as a reduction of additional paid-in capital in the accompanying condensed consolidated statements of changes in equity. The Trust is structured as an umbrella partnership REIT ("UPREIT") and contributes all proceeds from its various equity offerings to EROP. For every one share of common stock offered and sold by EdR for cash, EdR must contribute the net proceeds to EROP and, in return, EROP will issue one OP Unit to EdR. Income taxes EdR qualifies as a REIT under the Internal Revenue Code of 1986, as amended (the "Code"). EdR is generally not subject to federal, state and local income taxes on any of its taxable income that it distributes if it distributes at least 90% of its REIT taxable income for each tax year to its stockholders and meets certain other requirements. If EdR fails to qualify as a REIT for any taxable year, EdR will be subject to federal, state and local income taxes (including any applicable alternative minimum tax) on its taxable income. The Trust has elected to treat certain of its subsidiaries, including the Management Company, as TRSs. A TRS is subject to federal, state and local income taxes. The Management Company provides management services and through the Development Company, provides development services, which if directly provided by the Trust would jeopardize EdR’s REIT status. Deferred tax assets and liabilities are recognized based on the difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect in the years in which those temporary differences are expected to reverse. The Trust had no unrecognized tax benefits as of June 30, 2017 and December 31, 2016 . The Trust and its subsidiaries file federal and state income tax returns. As of June 30, 2017 , open tax years generally included tax years for 2013, 2014, 2015 and 2016. The Trust’s policy is to include interest and penalties related to unrecognized tax benefits in general and administrative expenses. For the three and six months ended June 30, 2017 and 2016 , the Trust had no interest or penalties recorded related to unrecognized tax benefits. Goodwill and other intangible assets Goodwill is tested annually for impairment as of December 31, and is tested for impairment more frequently if events and circumstances indicate that the carrying value of the assets might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. The accumulated impairment loss recorded is $0.4 million . No additional impairment has been recorded through June 30, 2017 . The carrying value of goodwill was $3.1 million as of June 30, 2017 and December 31, 2016 , of which $2.1 million was recorded on the management services reportable segment and $0.9 million was recorded on the development consulting services reportable segment. Goodwill is not subject to amortization. Other intangible assets generally include in-place leases acquired in connection with acquisitions of collegiate housing properties. As of June 30, 2017 and December 31, 2016 , gross in-place leases totaled $12.2 million and $7.4 million , respectively, and are being amortized over the life of the remaining lease term, which is generally less than one year. Amortization expense totaled $3.0 million and $0.8 million for the three months ended June 30, 2017 and 2016 , respectively. Amortization expense totaled $6.4 million and $0.9 million for the six months ended June 30, 2017 and 2016, respectively. As of June 30, 2017 and December 31, 2016 , accumulated amortization totaled $10.0 million and $3.6 million , respectively. The carrying value of other intangible assets was $2.2 million and $3.8 million as of June 30, 2017 and December 31, 2016 , respectively. Investment in unconsolidated entities The Trust accounts for its investments in unconsolidated joint ventures using the equity method whereby the costs of an investment are adjusted for the Trust’s share of earnings of the respective investment reduced by distributions received. The earnings and distributions of the unconsolidated joint ventures are allocated based on each owner’s respective ownership interests. These investments are classified as other assets or accrued expenses, depending on whether the distributions exceed the Trust’s contributions and share of earnings in the joint ventures, in the accompanying condensed consolidated balance sheets (see Note 5). Earnings per share Earnings per Share - The Trust Basic earnings per share is calculated by dividing net income available to common stockholders after accretion of redeemable noncontrolling interests by weighted average shares of common stock outstanding, including outstanding units in the Operating Partnership designated as LTIP Units ("LTIP Units"). Diluted earnings per share is calculated similarly, except that it includes the dilutive effect of the assumed exercise of potentially dilutive securities and the shares issuable upon settlement of the Forward Agreements using the treasury stock method. The Trust follows the authoritative guidance regarding the determination of whether certain instruments are participating securities. All unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are included in the computation of earnings per share under the two-class method. This results in shares of unvested restricted stock and LTIP Units being included in the computation of basic earnings per share for all periods presented. When noncontrolling interests are redeemable at other than fair value, increases or decreases in the carrying amount of the redeemable noncontrolling interests are reflected in earnings per share using the two-class method. Earnings per OP Unit - EROP Basic earnings per unit is calculated by dividing net income available to unitholders after accretion of redeemable noncontrolling interests by the weighted average number of OP Units and LTIP Units outstanding. Diluted earnings per unit is calculated similarly, except that it includes the dilutive effect of the assumed exercise of potentially dilutive securities and the shares issuable upon settlement of the Forward Agreements using the treasury stock method. EROP follows the authoritative guidance regarding the determination of whether certain instruments are participating securities. Recent accounting pronouncements In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" ("ASU 2016-18"). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and restricted cash. Therefore, amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows, and transfers between cash and cash equivalents and restricted cash are no longer presented within the statement of cash flows. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. The Trust anticipates retrospectively adopting this guidance on January 1, 2018. The Trust's initial analysis indicates the adoption of this ASU will result in the change in restricted cash to no longer be presented in the statement of cash flows as an investing cash flow. In August 2016, the FASB issued ASU 2016-15, " Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments " ("ASU 2016-15"). ASU 2016-15 addresses eight specific cash flow issues and intends to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows and will be applied retrospectively. This guidance is effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period, with early adoption permitted. The Trust adopted ASU 2016-15 effective January 1, 2017. As a result of this adoption, there was no impact to the condensed consolidated statements of cash flows for either period presented. In February 2016, the FASB issued ASU 2016-02, " Leases (Topic 842)" ("ASU 2016-02"), which requires a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years, on a modified prospective basis. The Trust's primary revenue is collegiate housing rental income; as such, the Trust is a lessor on a significant number of leases. The Trust is continuing to evaluate the potential impact of the ASU and believes it will continue to account for its leases in substantially the same manner due to the short-term nature (less than 12 months) of the leases. The most significant change for the Trust relates to ground lease agreements, which could result in recording the right-of-use asset and related liability on the balance sheet. The Trust plans to adopt ASU 2016-02 effective January 1, 2019 and is continuing to evaluate and quantify the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, " Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"), as amended by ASU 2015-04 to defer the effective date. The guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including the guidance on real estate derecognition for most transactions. ASU 2014-09 provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years and permits the use of either the retrospective or cumulative effect transition method. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. Since the issuance of ASU 2014-09, the FASB has issued ASU 2016-08 that is intended to improve the understandability of the implementation guidance regarding principal versus agent considerations and has issued ASU 2016-10 to clarify the identification of performance obligations and the implementation guidance related to licensing. The effective dates of these amendments are the same as ASU 2014-09. The Trust does not expect the adoption of this standard to have a material impact on its consolidated financial statements, as a substantial portion of its revenue consists of rental income from leasing arrangements, which is specifically excluded from this ASU. The Trust's initial analysis of its non-lease related revenue contracts, which comprise less than 15% of consolidated revenues, indicates the adoption of this ASU will not have a material effect on the consolidated financial statements; however, the Trust is still in the process of evaluating this ASU.

Acquisition and development of real estate investments	Acquisition and development of real estate investments Acquisition of collegiate housing properties 2017 Acquisitions During the six months ended June 30, 2017 , the Trust completed the following two collegiate housing property acquisitions, which were determined to be asset acquisitions under ASU 2017-01: Name Primary University Served Acquisition Date # of Beds # of Units Contract Price (in thousands) Retreat at Corvallis Oregon State University, Oregon January 2017 1,016 330 $ 99,450 319 Bragg Auburn University, Alabama February 2017 305 86 $ 28,500 Below is the allocation of the purchase price as of the date of the acquisition (in thousands): Retreat at Corvallis 319 Bragg Total Collegiate housing property $ 95,785 $ 27,475 $ 123,260 In-place leases 3,780 1,055 4,835 Other assets 617 2 619 Current liabilities (936 ) (131 ) (1,067 ) Total net assets acquired $ 99,246 $ 28,401 $ 127,647 The $0.3 million difference between the aggregate contracted price of $128.0 million and the net assets set forth in the table above represents working capital and other liabilities that were not part of the contractual purchase price, but were acquired. 2016 Acquisitions During the year ended December 31, 2016 , the Trust completed the following five collegiate housing property acquisitions: Name Primary University Served Acquisition Date # of Beds # of Units Contract Price (in thousands) Lokal Colorado State University, Colorado March 2016 194 79 $ 24,600 The Hub at Madison University of Wisconsin, Wisconsin May 2016 1,038 341 $ 188,500 Pura Vida Place Colorado State University, Colorado August 2016 100 52 $ 12,000 Carriage House Colorado State University, Colorado August 2016 94 54 $ 12,000 Urbane University of Arizona, Arizona September 2016 311 104 $ 50,000 These acquisitions were accounted for as business combinations as they occurred prior to the adoption of ASU 2017-01. Below is the allocation of the purchase price to the fair values of assets acquired and liabilities assumed as of the date of acquisition (in thousands): Lokal The Hub at Madison Pura Vida Place Carriage House Urbane Total Collegiate housing property 23,653 189,832 11,498 11,528 47,999 $ 284,510 In-place leases 849 3,588 502 472 1,984 7,395 Other assets 3 87 5 4 18 117 Current liabilities (148 ) (7,442 ) (144 ) (67 ) (584 ) (8,385 ) Total net assets acquired $ 24,357 $ 186,065 $ 11,861 $ 11,937 $ 49,417 $ 283,637 The $3.5 million difference between the contracted price of $287.1 million and the net assets set forth in the table above includes contingent consideration related to the acquisition of The Hub at Madison, which was initially estimated at $5.3 million and represents additional purchase price related to future operating performance of the applicable property and future tax assessments. Of this amount, $3.1 million was paid out during 2016. As of June 30, 2017 and December 31, 2016 , $2.3 million was estimated and recorded as a contingent consideration liability, based upon probability of achieving certain operating performance metrics. The estimated range of possible outcomes is between $0.0 million and $4.5 million . The remaining difference between the contracted price and the net assets set forth above represents working capital and other liabilities that were not part of the contractual purchase price, but were acquired. In connection with the acquisition of Urbane, the Trust formed a limited liability company to acquire an interest in the legal entity owning the collegiate housing property. In addition to the $10.0 million capital contribution, the Trust advanced $23.6 million to the seller. Under the terms of the agreement, the Trust has a call exercisable on September 8, 2017 to acquire the remaining ownership interest from the seller and the seller similarly has a put to sell their interests to the Trust. The exercise price is substantially fixed and the exercise dates are within one month of each other. The Trust evaluated the LLC as a VIE and determined it was the primary beneficiary because it directs the activities that most significantly impact the economic performance of the entity. Therefore, the Trust has consolidated the VIE since the date of acquisition. The put and call arrangement was evaluated, and it was determined the noncontrolling interests represent a liability because of the substantially fixed exercise prices and stated exercise dates; therefore, the economic substance is a financing arrangement. The Trust has recorded the liability at the present value of the fixed price settlement amount ( $14.9 million reflected in accounts payable and accrued expenses) and will accrete the liability to the fixed price over the contractual term. The amount recorded at June 30, 2017 and December 31, 2016 approximates the redemption or settlement amount due to the short term of the contractual period. No earnings have been attributed to noncontrolling interests in the accompanying condensed consolidated statements of net income and comprehensive income. The Trust is also obligated to pay the seller contingent consideration of up to $1.5 million if certain performance conditions are met for the 2017/2018 lease year. Conversely, if the operating performance of the property does not achieve certain performance metrics, the seller is required to reimburse the Trust for up to $1.5 million of the purchase price. Based on the assessment of the probability of achieving the performance metrics as of the acquisition date, no contingent consideration was initially recorded at the acquisition date. As of June 30, 2017 and December 31, 2016 , $1.5 million and $1.0 million , respectively, were estimated and recorded as a contingent consideration liability, based upon probability of achieving certain operating performance metrics. The unaudited pro forma information for the 2016 acquisitions presented below for the six months ended June 30, 2016 and 2015 assumes an acquisition date of January 1, 2015 and is not necessarily indicative of results that would have occurred or which may occur (in thousands, except per share and per unit amounts): Six months ended June 30, 2016 (1) 2015 (1)(2) Total revenue attributable to the Trust and EROP $ 140,476 $ 121,961 Net income attributable to the Trust $ 32,634 $ 9,992 Net income per share attributable to common shareholders - basic and diluted $ 0.50 $ 0.21 Net income attributable to EROP $ 32,740 $ 10,041 Net income per unit attributable to unitholders - basic and diluted $ 0.50 $ 0.21 (1) As Urbane first opened for the 2016/2017 lease year (August 2016), supplemental pro forma revenue and net income information is not included for the six months ended June 30, 2016 and 2015.

Equity Method Investments and Joint Ventures [Abstract]
Investments in unconsolidated entities	Investments in unconsolidated entities As of June 30, 2017 and December 31, 2016 , the Trust had investments in the following unconsolidated joint ventures (see Note 2), all of which are accounted for under the equity method: • a 50% interest in 1313 5th Street MN Holdings, LLC, a Delaware limited liability company, which owns the collegiate housing property referred to as The Marshall at the University of Minnesota; • a 50% interest in West Clayton Athens GA Owner, LLC, a Delaware limited liability company, which owns the collegiate housing property referred to as Georgia Heights at the University of Georgia; • a 25% interest in University Village-Greensboro LLC, a Delaware limited liability company, which owns the collegiate housing property referred to as University Village - Greensboro; and • a 14% interest in Elauwit Networks, a South Carolina limited liability company. The Trust participates in major operating decisions of, but does not control, these entities; therefore, the equity method is used to account for these investments. The following is a summary of the results of operations related to the unconsolidated joint ventures for the six months ended June 30, 2017 and 2016 (unaudited, in thousands): Results of Operations of Unconsolidated Entities: For the six months ended June 30, 2017 2016 Revenues $ 12,130 $ 17,023 Net income (1) $ 837 $ 151 Equity in earnings (losses) of unconsolidated entities $ 384 $ (137 ) (1) Net income for the periods presented above equals income from continuing operations. As of June 30, 2017 and December 31, 2016 , the Trust had $26.9 million and $27.0 million , respectively, of investments in unconsolidated entities classified in other assets in the accompanying condensed consolidated balance sheets. As of June 30, 2017 and December 31, 2016 , liabilities are recorded totaling $2.0 million and $1.9 million , respectively, related to investments in unconsolidated entities where distributions exceeded contributions and equity in earnings and the Trust has historically provided financial support; therefore, these investments are classified in accounts payable and accrued expenses in the accompanying condensed consolidated balance sheets (see Note 2).

Debt Disclosure [Abstract]
Debt	Debt Revolving credit facility On November 19, 2014 , the Operating Partnership entered into a Fifth Amended and Restated Credit Agreement (the “Fifth Amended Revolver”). The Fifth Amended Revolver has a maximum availability of $500.0 million and an accordion feature to $1.0 billion , which may be exercised during the first four years subject to satisfaction of certain conditions. The Fifth Amended Revolver is scheduled to mature on November 19, 2018 with a one -year extension option, provided that certain conditions are met. EdR serves as the guarantor for any funds borrowed by the Operating Partnership under the Fifth Amended Revolver. The interest rate per annum applicable to the Fifth Amended Revolver is, at the Operating Partnership’s option, equal to a base rate or the London InterBank Offered Rate ("LIBOR") plus an applicable margin based upon our leverage. As of June 30, 2017 , the interest rate applicable to the Fifth Amended Revolver was 2.48% . If amounts are drawn, due to the fact that the Fifth Amended Revolver bears interest at variable rates, cost approximates the fair value. In addition, the Operating Partnership also incurs an unused fee equal to either 0.15% or 0.25% of the unused balance, based on outstanding commitments. As of June 30, 2017 , the outstanding balance under the Fifth Amended Revolver was $345.0 million ; thus, the Trust's remaining availability was $155.0 million at June 30, 2017 . The Fifth Amended Revolver contains customary affirmative and negative covenants and contains financial covenants that, among other things, require the maintenance of certain minimum ratios of EBITDA (earnings before payment or charges of interest, taxes, depreciation, amortization or extraordinary items) as compared to interest expense and total fixed charges. The financial covenants also include consolidated net worth and leverage ratio tests, and distributions are prohibited in excess of 95% of funds from operations ("FFO") except to comply with the legal requirements to maintain REIT status. As of June 30, 2017 , the Operating Partnership was in compliance with all covenants under the Fifth Amended Revolver. Unsecured term loan facility On January 18, 2017, the Operating Partnership and certain subsidiaries entered into the Second Amended and Restated Credit Agreement. Under the Second Amended and Restated Credit Agreement, the unsecured term loans have an aggregate principal amount of $187.5 million , consisting of a $122.5 million Tranche A term loan (the “Tranche A Term Loan”) and a $65.0 million Tranche B term loan (the “Tranche B Term Loan” and, together with the Tranche A Term Loan, the “Term Loans”). The Tranche A Term Loan matures on January 13, 2021 and the Tranche B Term Loan matures on January 18, 2022. The Second Amended and Restated Credit Agreement contains an accordion feature pursuant to which the Borrowers may request that the total aggregate amount of the Term Loans be increased to $250.0 million , which may be allocated to Tranche A or Tranche B, subject to certain conditions, including obtaining commitments from any one or more lenders to provide such additional commitments. The interest rate per annum on the Tranche A Term Loan is, at the Operating Partnership’s option, equal to a base rate or LIBOR plus an applicable margin ranging from 120 to 190 basis points. The interest rate per annum on the Tranche B Term Loan is, at the Operating Partnership’s option, equal to a base rate or LIBOR plus an applicable margin ranging from 120 to 190 basis points. The applicable margin for the Term Loans is based on leverage. At June 30, 2017 and December 31, 2016 , the aggregate outstanding balance under the Term Loans was $186.4 million and $186.7 million , respectively, which is presented net of unamortized deferred financing costs of $1.1 million and $0.8 million , respectively, in the accompanying condensed consolidated balance sheets. The Second Amended and Restated Credit Agreement contains customary affirmative and restrictive covenants substantially similar to those contained in the Fifth Amended Revolver. EdR serves as the guarantor for any funds borrowed under the First Amended and Restated Credit Agreement. As of June 30, 2017 , the Operating Partnership was in compliance with all covenants of the Second Amended and Restated Credit Agreement. In connection with entering into the First Amended and Restated Credit Agreement on November 19, 2014, which was superseded by the Second Amended and Restated Credit Agreement, the Operating Partnership entered into multiple interest rate swaps with notional amounts totaling $187.5 million to hedge the interest payments on the LIBOR-based Term Loans (see Note 11) through the Term Loans' initial maturity date. The Operating Partnership also entered into forward starting interest rate swaps (see Note 11) concurrently with executing the Second Amended and Restated Credit Agreement, which extended the term of the Tranche B Term Loan by three years to January 18, 2022. As of June 30, 2017 , the effective interest rate on the Tranche A Term Loan was 3.50% (weighted average swap rate of 2.30% plus the current margin of 1.20% ) and the effective interest rate on the Tranche B Term Loan was 2.86% (weighted average swap rate of 1.66% plus the current margin of 1.20% ). Unsecured senior notes On November 24, 2014, the Operating Partnership completed the public offering of $250.0 million aggregate principal amount of unsecured senior notes (the "Unsecured Senior Notes") under an existing shelf registration statement. The 10 -year Unsecured Senior Notes were issued at 99.991% of par value with a coupon of 4.6% per annum and are fully and unconditionally guaranteed by EdR. Interest on the Unsecured Senior Notes is payable semi-annually on June 1 and December 1 of each year. The Unsecured Senior Notes will mature on December 1, 2024. At June 30, 2017 and December 31, 2016 , the outstanding balance under the Unsecured Senior Notes was $248.1 million and $247.9 million , respectively, which is presented net of unamortized deferred financing costs of $1.9 million and $2.1 million , respectively, in the accompanying condensed consolidated balance sheets. The terms of Unsecured Senior Notes contain certain covenants that restrict the ability of EdR and the Operating Partnership to incur additional secured and unsecured indebtedness. In addition, the Operating Partnership must maintain a minimum ratio of unencumbered asset value to unsecured debt, as well as a minimum interest coverage level. As of June 30, 2017 , the Operating Partnership was in compliance with all covenants. Mortgage and construction debt As of June 30, 2017 and December 31, 2016 , mortgage and construction notes payable consist of the following, which were secured by the underlying collegiate housing properties (dollars in thousands): Outstanding Balance at Property June 30, 2017 December 31, 2016 Interest Rate at June 30, 2017 Interest Rate Type Maturity Date University Towers — 32,950 n/a Mortgage Debt — 32,950 n/a The Oaks on the Square - Phase IV 29,772 29,626 2.80 % Variable 10/20/2017 Construction Loans 29,772 29,626 2.80 % Total mortgage and construction debt / weighted average rate 29,772 62,576 2.80 % Unamortized deferred financing costs (21 ) (56 ) Total net of unamortized deferred financing costs 29,751 62,520 Less current portion, net of unamortized deferred financing costs (29,751 ) (62,520 ) Total mortgage and construction debt, net of current portion $ — $ — Mortgage debt and construction loans During the six months ended June 30, 2017 , the Operating Partnership repaid in full the variable-rate mortgage debt secured by the University Towers collegiate housing property, which had an unpaid principal balance of $33.0 million . The interest rate was 2.9% per annum and the mortgaged debt was scheduled to mature on July 1, 2017. The construction loan secured by the Oaks of the Square - Phase IV contains customary financial covenants, such as minimum debt service ratios. As of June 30, 2017 , the Operating Partnership was in compliance with all covenants. The following table reconciles the carrying amount of mortgage and construction notes payable, net of unamortized deferred financing costs, for the six months ended June 30, 2017 and the year ended December 31, 2016 (in thousands): June 30, 2017 December 31, 2016 Balance, beginning of period $ 62,520 $ 204,511 Additions to principal 146 40,974 Repayments of principal (32,950 ) (183,862 ) Amortization of debt premium — (49 ) Write-off of debt premium related to debt pay off — (523 ) (Increase) decrease in deferred financing costs, net 35 1,469 Balance, end of period $ 29,751 $ 62,520 The scheduled maturities of outstanding indebtedness as of June 30, 2017 are as follows (in thousands): Year 2017 (six months ending December 31, 2017) $ 29,772 2018 345,000 2019 — 2020 — 2021 122,500 2022 65,000 Thereafter 250,000 Total 812,272 Unamortized deferred financing costs (3,067 ) Outstanding as of June 30, 2017, net of unamortized deferred financing costs $ 809,205

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies For its third-party development projects, the Trust commonly provides alternate housing and project cost guarantees, subject to certain conditions. Alternate housing guarantees generally require the university to provide on-campus housing or the Trust to provide substitute living quarters and transportation for students to and from the university if the project is not complete by an agreed-upon date. Under project cost guarantees, the Trust is responsible for the construction costs of a project in excess of an approved budget. The budget consists primarily of costs included in the general contractors’ guaranteed maximum price contract (“GMP”). In most cases, the GMP obligates the general contractor, subject to force majeure and approved change orders, to provide completion date guarantees and to cover cost overruns and liquidated damages. In addition, the GMP is typically secured with payment and performance bonds. The Operating Partnership and various joint venture partners have jointly and severally guaranteed partial repayment on third-party mortgage and construction debt secured by the following underlying collegiate housing properties, all of which are unconsolidated joint ventures. The Operating Partnership is liable to the lender for any loss, damage, cost, expense, liability, claim or other obligation incurred by the lender arising out of or in connection with certain non-recourse exceptions in connection with the debt. Pursuant to the respective operating agreements, the joint venture partners agreed to indemnify, defend and hold harmless the Trust with respect to such obligations, except to the extent such obligations were caused by the willful misconduct, gross negligence, fraud or bad faith of the Operating Partnership or its employees, agents or affiliates. Therefore, exposure under the guaranties for obligations not caused by the willful misconduct, gross negligence, fraud or bad faith of the Operating Partnership or its employees, agents or affiliates are not expected to exceed the Operating Partnership's proportionate interest in the related mortgage debt in the case of the non-recourse, carve-out guaranty, or in the Operating Partnership's proportionate interest in the partial repayment guaranty, as applicable. The following summarizes the Operating Partnership's exposure under such guaranties (dollars in thousands): June 30, 2017 December 31, 2016 Joint Venture Balance Operating Partnership's Proportionate Interest Joint Venture Balance Operating Partnership's Proportionate Interest Ownership Percent Loan Balance Partial Repayment Guarantee Loan Balance Partial Repayment Guarantee Loan Balance Partial Repayment Guarantee Loan Balance Partial Repayment Guarantee University Village - Greensboro 25 % $ 22,741 n/a $ 5,685 n/a $ 22,934 n/a $ 5,734 n/a The Marshall 50 % 55,397 8,767 27,699 4,384 55,838 8,767 27,919 4,384 Georgia Heights 50 % 34,868 7,230 17,434 3,615 34,914 7,230 17,457 3,615 During October 2014, the Operating Partnership and LeylandAlliance LLC entered into a $38.0 million construction loan for the fourth phase of the The Oaks on the Square project. The Operating Partnership and LeylandAlliance LLC jointly committed to provide a guarantee of repayment for the construction loan. As of June 30, 2017 , $37.2 million had been drawn on the construction loan, of which $7.4 million was attributable to LeylandAlliance LLC, and has not been included in our condensed consolidated financial statements. As owners and operators of real estate, environmental laws impose ongoing compliance requirements on the Trust. The Trust is not aware of any environmental matters or liabilities with respect to the collegiate housing communities that would have a material adverse effect on the Trust’s condensed consolidated financial condition or results of operations. In the normal course of business, the Trust is subject to claims, lawsuits and legal proceedings. While it is not possible to ascertain the ultimate outcome of such matters, in management’s opinion, the liabilities, if any, are not expected to have a material effect on the Trust's financial position, results of operations or liquidity.

Noncontrolling Interest [Abstract]
Noncontrolling interests	Noncontrolling interests Operating Partnership Joint Ventures: As of June 30, 2017 , EROP had entered into nine joint venture agreements to develop, own and manage certain collegiate housing communities. All of these joint ventures are VIEs that meet the criteria for consolidation (see Note 2). EROP's joint venture partners' investments in all but one of the communities under development meet the requirements to be classified outside of permanent equity, and are therefore classified as redeemable noncontrolling interests in the accompanying condensed consolidated balance sheets and net income (loss) attributable to noncontrolling interests in the accompanying condensed consolidated statements of income and comprehensive income due to the partners' ability to put their ownership interests to EROP for cash based on fair value or at substantially fixed exercise prices as stipulated in the operating agreements. These contributions occurred during 2016 and 2017, and the developments are still under construction. In connection with the acquisitions of The Hub at Madison and Urbane (see Note 3), the Trust, through joint ventures, acquired a controlling interest in the legal entities owning the collegiate housing properties. At June 30, 2017 , the partners' interests in The Hub at Madison joint venture and Urbane joint venture were 1.6% and 3.0% , respectively. The partners' ownership interests in both joint ventures were accounted for as redeemable noncontrolling interests in the accompanying condensed consolidated balance sheets due to the partners' ability to put their respective ownership interests to the Operating Partnership for cash based on fair value. The share in net income (loss) attributable to noncontrolling interests is recorded in the accompanying condensed consolidated statements of income and comprehensive income. At June 30, 2017 and December 31, 2016 , the Urbane joint venture partner also has an additional interest in the legal entity; however, it was determined the noncontrolling interest represented a financing arrangement that has been recorded as an accrued liability. The value of the joint venture partners' investments in the development projects and acquired properties redeemable at fair value are reported at the greater of fair value or historical cost at the end of each reporting period. At June 30, 2017 and December 31, 2016 , the joint venture partners' investment in development projects was recorded at historical cost, as the carrying value approximates fair value. At June 30, 2017 and December 31, 2016 , the joint venture partners' interest in the acquired properties was recorded at fair value. The joint venture partners’ investments in development projects redeemable at substantially fixed prices are considered redeemable at other than fair value. The change in redemption value during the six months ended June 30, 2017 is reflected in additional paid-in capital and is also included in calculating earnings per share using the two-class method. EROP also owns a 72.7% interest in University Towers Operating Partnership, LP. This entity is considered a VIE that meets the criteria for consolidation (see Note 2). The units of the limited partnership interest of University Towers Operating Partnership, LP (“University Towers Operating Partnership Units”) are also classified as noncontrolling interests. The University Towers Operating Partnership Units are redeemable at the option of the holder, and they participate in net income and distributions. Accordingly, EROP has determined that the University Towers Operating Partnership Units meet the requirements to be classified outside of permanent equity, and are therefore also classified as redeemable noncontrolling interests in the accompanying condensed consolidated balance sheets. Income related to such units is recorded as net income (loss) attributable to noncontrolling interests in the accompanying condensed consolidated statements of income and comprehensive income. As of June 30, 2017 and December 31, 2016 , there were 69,086 University Towers Operating Partnership Units outstanding. The value of redeemable University Towers Operating Partnership Units is reported at the greater of fair value or historical cost at the end of each reporting period. As of June 30, 2017 and December 31, 2016 , EROP reported the redeemable noncontrolling interests at fair value, which was greater than historical cost. The following table sets forth activity with the redeemable noncontrolling interests for the six months ended June 30, 2017 and 2016 (in thousands): Six months ended June 30, 2017 2016 Beginning balance $ 32,160 $ 5,248 Net loss (352 ) (5 ) Contributions from redeemable noncontrolling interests 12,404 — Adjustments to report redeemable noncontrolling interests at fair value 80 518 Purchase and return of equity to noncontrolling partner's interest — (2,910 ) Distributions (322 ) (74 ) Accretion of redeemable noncontrolling interests 1,207 — Ending balance $ 45,177 $ 2,777 Redeemable Limited Partner Units: The OP Units that may be tendered for redemption by the holders thereof for cash, or at EdR's option, for shares of EdR common stock are classified as redeemable limited partner units in the mezzanine section of the accompanying condensed consolidated balance sheets of the Operating Partnership. The OP Units are reported at the greater of fair value or historical cost at the end of each reporting period. As of June 30, 2017 and December 31, 2016 , EROP reported the redeemable limited partner units at fair value (considered Level 1 as determined based on the market price of EdR's common stock), which was greater than historical cost. During the six months ended June 30, 2017 and 2016, 27,500 and 25,000 OP Units were redeemed for 27,500 and 25,000 shares of EdR's common stock, respectively. As of June 30, 2017 and December 31, 2016 , there were 153,651 and 159,698 OP Units outstanding, respectively, other than OP Units held by EdR. Below is a table summarizing the activity of redeemable limited partner units for the six months ended June 30, 2017 and 2016 (in thousands): Six months ended June 30, 2017 2016 Beginning balance $ 6,789 $ 8,312 Net income 45 111 Distributions (127 ) (161 ) Reclassification of vested LTIP Units to redeemable limited partner units 522 244 Redemption of redeemable partner units in exchange for common stock or redemption for cash (1,138 ) (938 ) Adjustments to report redeemable limited partner units at fair value (84 ) 1,483 Ending balance $ 6,007 $ 9,051 The Trust The Trust accounts for the joint ventures discussed above as VIEs and consolidates such entities in the same manner as EROP. The noncontrolling interests of the Trust include third-party equity interests in one joint venture development which is presented as a component of equity in the Trust’s accompanying condensed consolidated balance sheets. The Trust’s redeemable noncontrolling interests include: (1) the redeemable limited partners presented in the accompanying condensed consolidated balance sheets of EROP; (2) the University Towers Operating Partnership Units; (3) our partners' investments in certain joint venture developments; and (4) our partners' investments in certain acquired communities, which are presented as redeemable noncontrolling interests in the accompanying condensed consolidated balance sheets of EROP.

Equity [Abstract]
Equity	Equity Stockholders’ Equity - The Trust During October 2014, the Trust entered into agreements to establish an at-the-market equity offering program (the "2014 ATM Program") pursuant to which the Trust was authorized to sell a maximum of $150.0 million in shares of EdR common stock. The Trust sold approximately 2.3 million shares under these distribution agreements during the six months ended June 30, 2016 and received net proceeds of approximately $93.5 million after deducting sales agents' fees and other expenses payable by the Trust. On January 15, 2016, the Trust completed a follow-on equity offering of approximately 6.3 million shares of EdR common stock. The Trust received approximately $215.1 million in net proceeds from the offering after deducting the underwriting discount and other offering expenses payable by the Trust. Of the total net proceeds, approximately $108.5 million was used to pay off $98.2 million of fixed rate mortgage debt bearing an average effective interest rate of 5.4% and $10.3 million of prepayment penalties associated with the early extinguishment of debt. On March 24, 2016, EdR issued approximately 0.5 million shares of its common stock for a total of approximately $20.0 million pursuant to the direct stock purchase component of the Amended and Restated Dividend Reinvestment and Direct Stock Purchase Plan. On August 1, 2016 and February 28, 2017, the Trust entered into equity distribution agreements to establish new ATM Programs under which the Trust is authorized to sell a maximum of $300.0 million and $500.0 million , respectively, in shares of EdR common stock. We refer to the ATM Program implemented in February 28, 2017 as the "2017 ATM Program." Under these equity distribution agreements, EdR may make sales of common stock through at-the-market transactions or pursuant to forward sales agreements (the “Forward Agreements”) with certain counterparties. In connection with any Forward Agreement, the relevant forward purchaser will borrow from third parties and, through the relevant sales agent, sell a number of shares of EdR common stock underlying the particular Forward Agreement. The Trust does not initially receive any proceeds from any sale of borrowed shares. At June 30, 2017 , a summary of the outstanding Forward Agreements is set forth in the table below (shares in thousands): Date of Forward Agreement Shares Sold Volume Weighted Average Sale Price Per Share Initial Forward Price (1) Final Settlement Date (2) August 2, 2016 273 $ 47.93 $ 47.33 December 29, 2017 August 8, 2016 550 46.86 46.28 December 29, 2017 August 15, 2016 185 46.55 45.97 December 29, 2017 August 22, 2016 213 45.59 45.02 December 29, 2017 August 29, 2016 3,323 43.36 42.82 December 29, 2017 October 3, 2016 2,408 41.00 40.51 December 29, 2017 February 28, 2017 361 41.55 41.14 December 31, 2018 7,313 $ 43.07 $ 42.64 (1) The initial forward price under each Forward Agreement is equal to 99.00% of the volume weighted average price at which the shares of EdR common stock are sold by the applicable forward seller as adjusted to reflect changes in the federal funds rate and to account for dividends paid to holders of EdR common stock. The initial forward prices presented in this table are for illustrative purposes only as the actual amount of proceeds per share to be received by the Trust upon settlement will be determined on the applicable settlement date based on adjustments made to the initial forward price to reflect the then-current federal funds rate and the amount of dividends paid to holders of EdR common stock over the term of the Forward Agreement. (2) Represents the final date on which shares sold under each Forward Agreement may be settled. As of June 30, 2017 , the Trust had approximately $485.0 million available for issuance under its 2017 ATM Program. The Trust generally has the ability to determine the dates and method of settlement, subject to certain conditions and the right of the counterparty to accelerate settlement under certain circumstances. The Trust currently expects to fully physically settle each Forward Agreement by issuing shares of EdR common stock on one or more dates specified by the Trust prior to the maturity date of the applicable Forward Agreement, in which case the Trust expects to receive aggregate net cash proceeds at settlement equal to the number of shares of common stock underlying the applicable Forward Agreement multiplied by the relevant forward sale price. However, subject to certain exceptions, the Trust may also elect, in its discretion, to cash settle or net share settle a particular Forward Agreement, in which case the Trust may not receive any proceeds (in the case of cash settlement) or will not receive any proceeds (in the case of net share settlement), and the Trust may owe cash (in the case of cash settlement) or shares of EdR common stock (in the case of net share settlement) to the relevant counterparty. The Trust accounts for shares of EdR common stock reserved for issuance upon settlement of each Forward Agreement as equity. Before the issuance of shares of EdR common stock, if any, upon physical or net share settlement of the Forward Agreements, the Trust expects that the shares issuable upon settlement of the Forward Agreements will be reflected in its diluted earnings per share calculations using the treasury stock method. Under this method, the number of shares of EdR common stock used in calculating diluted earnings per share is deemed to be increased by the excess, if any, of the number of shares of common stock that would be issued upon full physical settlement of the Forward Agreements over the number of shares of common stock that could be purchased by the Company in the open market (based on the average market price during the period) using the proceeds receivable upon full physical settlement (based on the adjusted forward sale price at the end of the reporting period). If and when the Trust physically or net share settles any Forward Agreement, the delivery of shares of EdR's common stock would result in an increase in the number of shares outstanding and dilution to basic earnings per share. Partners’ Capital - Operating Partnership In connection with the equity offering and ATM Programs discussed above, the Operating Partnership issues OP Units to EdR equivalent to the number of shares of common stock issued by EdR.

Incentive plans	Incentive plans On May 10, 2017, EdR's stockholders approved the Education Realty Trust, Inc. 2017 Omnibus Equity Incentive Plan (the "2017 Plan"). The purpose of the 2017 Plan is to promote the interests of the Trust and its stockholders by attracting, motivating and retaining talented executive officers, employees and directors of the Trust and linking their compensation to the long-term interests of the Trust and its stockholders. The 2017 Plan replaced the Education Realty Trust, Inc. 2011 Omnibus Equity Incentive Plan (the "2011 Plan") in its entirety and authorized the grant of the 346,111 shares that remained available for grant under the 2011 Plan, as well as 1,000,000 additional shares. As of June 30, 2017 , the Trust had 1,346,111 shares of its common stock reserved for issuance pursuant to the 2017 Plan. Automatic increases in the number of shares available for issuance are not provided. The 2017 Plan provides for the grant of stock options, restricted stock, restricted stock units (“RSUs”), stock appreciation rights, other stock-based incentive awards to employees, directors and other key persons providing services to the Trust. The 2017 Plan limits the number of shares and LTIP units subject to awards granted during any calendar year to any non-employee director, together with cash fees paid during the calendar year, to a maximum of $500,000 in total value. A restricted stock award is an award of EdR’s common stock that is subject to restrictions on transferability and other restrictions as EdR's compensation committee determines in its sole discretion on the date of grant. The restrictions may lapse over a specified period of employment or the satisfaction of pre-established criteria as the compensation committee may determine. Except to the extent restricted under the award agreement, a participant awarded restricted stock will have all of the rights of a stockholder as to those shares, including, without limitation, the right to vote and the right to receive dividends or distributions on the shares. Unearned compensation related to restricted stock is recorded as expense over the applicable vesting period. The value is determined based on the market value of EdR’s common stock on the grant date. During the three and six months ended June 30, 2016 , compensation expense of $0.1 million was recognized in the accompanying condensed consolidated statements of income and comprehensive income, related to the vesting of restricted stock. As the applicable service period of all restricted stock ended on December 31, 2016, there was no compensation expense recorded during the three and six months ended June 30, 2017 related to restricted stock. An RSU award is an award that will vest based upon the Trust’s achievement of total stockholder returns at specified levels as compared to the average total stockholder returns of a peer group of companies and/or the National Association of Real Estate Investment Trusts Equity Index over three years (the “Performance Period”). At the end of the applicable Performance Period, EdR's compensation committee will determine the level and the extent to which the performance goal was achieved. RSUs that satisfy the performance goal will be converted into fully-vested shares of EdR’s common stock and the Trust will receive a tax deduction for the compensation expense at the time of vesting. Prior to vesting, the participants are not eligible to vote or receive dividends or distributions on the RSUs. Unearned compensation related to RSU awards is recorded as expense over the applicable vesting period. During the three and six months ended June 30, 2016 , compensation expense of $0.1 million and $0.3 million , respectively, was recognized in the accompanying condensed consolidated statements of income and comprehensive income, related to the vesting of RSUs. As the applicable service period of all RSUs ended on December 31, 2016, there was no compensation expense recorded during the three and six months ended June 30, 2017 related to RSUs. On January 1, 2017, 79,699 fully-vested shares of EdR's common stock were issued upon vesting of RSUs granted in 2014. The Trust's 2016 Long-Term Incentive Plan ("2016 LTIP"), adopted in 2016, and 2017 Long-Term Incentive Plan ("2017 LTIP"), adopted in 2017, provide that 25% of a participant’s award consists of a time-vested grant of LTIP Units in the Operating Partnership subject to the rights, preferences and other privileges as designated in the partnership agreement of the Operating Partnership (the “Partnership Agreement”). Similar to the treatment of restricted stock, the time-vested 2016 and 2017 LTIP Units vest over a three -year period and are valued for award purposes at a value equal to the price of EdR's common stock on the grant date. The time-vested 2016 and 2017 LTIP Units are entitled to voting and distribution rights from the effective date of the grant in accordance with the Partnership Agreement, but are non-transferable and non-convertible until fully vested. The remaining 75% of a participant’s award consists of a grant of performance-based 2016 and 2017 LTIP Units. The vesting of performance-based 2016 and 2017 LTIP Units is dependent upon the Trust's achievement of six performance criteria approved by EdR's compensation committee, over a three -year period, with a minimum, threshold and maximum performance standard for each performance criterion. Three of the performance criteria are based on market conditions and three have performance vesting conditions under ASC 718, " Compensation - Stock Compensation ". The fair value of the awards subject to market conditions was determined using a Monte Carlo simulation technique by an independent third party consultant. The fair value of the awards subject to performance conditions was calculated based on the closing market value of EdR's common stock on the grant date. The probability of achieving the performance conditions is assessed quarterly. The performance-based 2016 and 2017 LTIP Units are entitled to voting and distribution rights from the effective date of the grant in accordance with the Partnership Agreement, but are nontransferable and non-convertible until fully vested. After the determination of the achievement of the performance criteria, any performance-based 2016 and 2017 LTIP Units that were awarded but did not become vested LTIP Units will be canceled. Once fully vested, the 2016 and 2017 LTIP Units may be converted to OP Units in the Operating Partnership and thereafter, at the election of the unitholder, may be tendered for redemption for cash or for shares of EdR's common stock on a one-for-one basis at EdR's election in accordance with the terms of the Partnership Agreement. Compensation expense recognized in general and administrative expense in the accompanying condensed consolidated statements of income and comprehensive income related to the LTIP Units was $1.6 million and $1.3 million for the six months ended June 30, 2017 and 2016 , respectively. Compensation expense recognized in general and administrative expense in the accompanying condensed consolidated statements of income and comprehensive income related to the LTIP Units was $0.8 million and $0.9 million for the three months ended June 30, 2017 and 2016 , respectively. As of June 30, 2017 and December 31, 2016 , unearned compensation related to LTIP Units totaled $5.9 million and $4.2 million , respectively, and will be recorded as expense over the applicable vesting period. Total stock-based compensation expense recognized in general and administrative expense in the accompanying condensed consolidated statements of income and comprehensive income for the six months ended June 30, 2017 and 2016 was $1.6 million and $1.7 million , respectively. Total stock-based compensation expense recognized in general and administrative expense in the accompanying condensed consolidated statements of income and comprehensive income for the three months ended June 30, 2017 and 2016 was $0.8 million and $1.1 million , respectively. A summary of the stock-based incentive plan activity as of and for the six months ended June 30, 2017 and 2016 is as follows: Restricted Stock Awards Weighted-Average Grant Date Fair Value Per Restricted Stock Award RSU Awards Weighted-Average Grant Date Fair Value Per RSU LTIP Units Weighted-Average Grant Date Fair Value Per LTIP Unit Outstanding as of December 31, 2015 25,569 (1) $ 28.32 146,911 $ 20.58 155,774 $ 18.83 Granted — — — — 131,745 26.20 Vested (10,199 ) 31.92 (10,776 ) 22.95 (7,067 ) 18.83 Surrendered (7,508 ) 31.92 (43,596 ) 22.95 — — Outstanding as of June 30, 2016 7,862 (1) $ 26.46 92,539 $ 19.20 280,452 $ 22.29 Outstanding as of December 31, 2016 7,799 (1) $ 26.46 91,756 $ 19.20 280,452 $ 22.29 Granted — — — — 146,728 25.85 Vested (4,516 ) 26.46 (53,131 ) 19.20 (14,385 ) 36.30 Surrendered (3,283 ) 26.46 (38,625 ) 19.20 — — Outstanding as of June 30, 2017 — $ — — $ — 412,795 $ 22.80 (1) Represents unvested shares of restricted stock as of the date indicated.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and hedging activities	Derivatives and hedging activities Cash Flow Hedges of Interest Rate Risk The objectives in using interest rate derivatives are to add stability to interest expense and to manage the exposure to interest rate movements. To accomplish this objective, interest rate swaps are used as part of the interest rate risk management strategy. During the six months ended June 30, 2017 and 2016, such derivatives were used to hedge the variable cash flows associated with variable-rate debt. As of June 30, 2017 , six interest rate swaps were outstanding with a combined notional amount of $187.5 million that were designated as cash flow hedges of interest rate risk. Also as of June 30, 2017 , the Trust had three forward-starting interest rate swap agreements with an aggregate notional amount of $65.0 million . The Trust entered into these forward-starting interest rate swaps in order to lock in fixed interest rates on the extended term of the Tranche B Term Loan concurrently with executing the Second Amended and Restated Credit Agreement (see Note 6). Accordingly, the forward-starting interest rate swaps were designated as cash flow hedges of interest rate risk. The counter-parties to such swaps are major financial institutions. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives, which is immaterial for all periods presented, is recognized directly in earnings. During the next twelve months, an additional $1.3 million is estimated to be reclassified to earnings as an increase to interest expense. As of June 30, 2017 and December 31, 2016 , the fair value of the derivatives is as follows (in thousands): Liability Derivatives Derivatives designated as hedging instruments Balance Sheet Location June 30, 2017 December 31, 2016 Fair Value Fair Value Interest rate contracts Accounts payable and accrued expenses $ 2,851 $ 3,564 Total derivatives designated as hedging instruments $ 2,851 $ 3,564 The following table discloses the effect of the derivative instruments on the condensed consolidated statements of income and comprehensive income for the six months ended June 30, 2017 and 2016 (in thousands): Derivatives in Cash Flow Hedging Relationships Amount of Gain (Loss) Recognized in OCI on Derivative (Effective Portion) Location of Loss Reclassified from Accumulated OCI into Income (Effective Portion) Amount of (Loss) Reclassified from Accumulated OCI into Income (Effective Portion) 2017 Interest rate contracts $ (229 ) Interest expense $ (1,114 ) 2017 Forward-starting interest rate contracts $ (172 ) Interest expense $ — 2016 Interest rate contracts $ (6,044 ) Interest expense $ (1,556 ) The following table discloses the effect of the derivative instruments on the condensed consolidated statements of income and comprehensive income for the three months ended June 30, 2017 and 2016 (in thousands): Derivatives in Cash Flow Hedging Relationships Amount of Gain (Loss) Recognized in OCI on Derivative (Effective Portion) Location of Loss Reclassified from Accumulated OCI into Income (Effective Portion) Amount of (Loss) Reclassified from Accumulated OCI into Income (Effective Portion) 2017 Interest rate contracts $ (533 ) Interest expense $ (505 ) 2017 Forward-starting interest rate contracts $ (337 ) Interest expense $ — 2016 Interest rate contracts $ (1,815 ) Interest expense $ (773 ) The above contracts are subject to enforceable master netting arrangements that provide a right of offset with each counterparty; however, no offsetting positions exist due to certain duplicate terms across all contracts. Therefore, the derivatives are not subject to offset in the accompanying condensed consolidated balance sheets. Credit-risk-related Contingent Features The Operating Partnership has agreements with each of its derivative counterparties that contain a provision where if the Operating Partnership defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Operating Partnership could also be declared in default on its derivative obligations. In addition, the Operating Partnership has agreements with each of its derivative counterparties that contain a provision where the Operating Partnership could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Operating Partnership's default on the indebtedness. As of June 30, 2017 and December 31, 2016 , the fair value of derivatives related to these agreements, which includes accrued interest, but excludes any adjustment for nonperformance risk, was a liability of $3.0 million and $3.8 million , respectively. As of June 30, 2017 , the Operating Partnership has not posted any collateral related to these agreements. If the Operating Partnership had breached any of these provisions at June 30, 2017 , it could have been required to settle its obligations under the agreements at their termination value of $3.0 million .

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions used to value the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined in ASC 820, Fair Value Measurements and Disclosures ("ASC 820") as follows: • Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2 - Observable inputs other than those included in Level 1, for example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets. • Level 3 - Unobservable inputs reflecting management's own assumption about the inputs used in pricing the asset or liability at the measurement date. Non-financial assets measured at fair value on a nonrecurring basis consist of real estate assets and investments in partially owned entities that have been written-down to estimated fair value when it has been determined that asset values are not recoverable. Fair value is estimated relating to impairment assessments based upon an income capitalization approach (which considers prevailing market capitalization rates and operations of the community) or the negotiated sales price, if applicable. Based upon the inputs used to value properties under the income capitalization approach, valuations under this method are classified within Level 3 of the fair value hierarchy. For the communities for which the estimated fair value was based on negotiated sales prices, the valuation is classified within Level 2 of the fair value hierarchy. One non-financial asset was impaired during the year ended December 31, 2016 and was recorded on the accompanying condensed consolidated balance sheet as of December 31, 2016 . The asset was subsequently sold during the three months ended June 30, 2017. As discussed in Note 11, interest rate swaps are used to manage interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with the provisions of ASC 820, credit valuation adjustments are incorporated to appropriately reflect both nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of the derivative contracts for the effect of nonperformance risk, the Trust has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Although the Trust has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. The Trust has determined that the significance of the impact of the credit valuation adjustments made to its derivative contracts, which determination was based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all derivatives held as of June 30, 2017 and December 31, 2016 were classified as Level 2 of the fair value hierarchy. The Trust determined that the contingent consideration recognized in connection with the acquisition of the Hub at Madison (see Note 3) is a recurring fair value adjustment. The initial determination of fair value was based on a Monte Carlo simulation analysis of the potential payout. As the performance period extends over two years, it is expected that the fair value will be adjusted at each reporting date. The estimated range of final payout is currently estimated to be $0.0 million to $4.5 million . The Trust did not record an adjustment during the six months ended June 30, 2017 . The Trust has determined that the inputs used to value the contingent consideration fall within Level 3 of the fair value hierarchy, as such represent unobservable inputs. In connection with the acquisition of Urbane (see Note 3), the Trust is obligated to pay the seller contingent consideration of up to $1.5 million if certain performance conditions are met for the 2017/2018 lease year. Conversely, if the operating performance of the property does not achieve certain performance metrics, the seller is required to reimburse the Trust for up to $1.5 million of the purchase price. Subsequent to the initial valuation and based on the current assessment of the probability of achieving the performance metrics as of June 30, 2017 , a $0.5 million adjustment was recorded during the six months ended June 30, 2017 and is reflected in other expenses in the accompanying condensed consolidated statements of income and comprehensive income. The Trust determined that this measurement is a recurring fair value adjustment and will adjust the amount to fair value at each reporting date. The Trust has determined that the inputs used to value the contingent consideration fall within Level 3 of the fair value hierarchy, as such represent unobservable inputs. Redeemable noncontrolling interests in the Trust (OP Units and University Towers Operating Partnership Units) have a redemption feature and are marked to their redemption value. The redemption value is based on the fair value of EdR's common stock on the redemption date, adjusted for certain items. As the valuation is based on adjusted quoted prices in active markets for identical assets or liabilities at the measurement date, these instruments are classified in Level 2 of the fair value hierarchy. The table below presents the assets and liabilities measured at fair value on a recurring basis, aggregated by the level in the fair value hierarchy within which those measurements fall and summarizes the carrying amounts and fair values of these financial instruments as of June 30, 2017 and December 31, 2016 (in thousands): Carrying value Estimated Fair Value Level 1 Level 2 Level 3 June 30, 2017: Derivative financial instruments (liability position) $ 2,851 $ — $ 2,851 $ — Deferred compensation plan assets 737 737 — — Contingent consideration 3,750 — — 3,750 Redeemable noncontrolling interests measured at fair value: OP Units, LTIP Units and University Towers Operating Units 8,472 — 8,472 — Joint venture partners' interests in development joint ventures and acquisitions 42,712 — 36,839 — December 31, 2016: Derivative financial instruments (liability position) $ 3,564 $ — $ 3,564 $ — Deferred compensation plan assets 503 503 — — Contingent consideration liability 3,250 — — 3,250 Redeemable noncontrolling interests measured at fair value: OP Units, LTIP Units and University Towers Operating Units 9,361 — 9,361 — Joint venture partners' interest in development joint ventures and acquisitions 29,588 — 29,588 — The table below shows the reconciliation of Level 3 liabilities measured at fair value on a recurring basis (in thousands): Fair value, December 31, 2016 $ 3,250 Purchases, issuances and settlements, net — Adjustment of fair value during period 500 Transfers into Level 3 — Fair value, June 30, 2017 $ 3,750 Financial assets and liabilities that are not measured at fair value in our condensed consolidated financial statements include mezzanine notes receivable and debt. Estimates of the fair values of these instruments are based on assessments of available market information and valuation methodologies, including discounted cash flow analyses. Due to the fact that the Trust's unsecured revolving credit facility, unsecured term loan facility and construction loan bears interest at variable rates, carrying value approximates the fair value. The table below summarizes the gross carrying amounts and fair values of these financial instruments as of June 30, 2017 and December 31, 2016 (in thousands): June 30, 2017 Carrying value Estimated Fair Value Level 1 Level 2 Level 3 Notes receivable $ 500 $ — $ 456 $ — Senior unsecured notes 250,000 — 258,325 — Unsecured revolving credit facility 345,000 — 345,000 — Unsecured term loan facility 187,500 — 187,500 — Variable rate construction loan 29,772 — 29,772 — December 31, 2016 Carrying value Estimated Fair Value Level 1 Level 2 Level 3 Notes receivable $ 500 $ — $ 450 $ — Senior unsecured notes 250,000 — 246,305 — Unsecured revolving credit facility 20,000 — 20,000 — Unsecured term loan facility 187,500 — 187,500 — Variable rate mortgage and construction loans 62,576 — 62,576 — The Trust discloses the fair value of financial instruments for which it is practicable to estimate. The Trust considers the carrying amounts of cash and cash equivalents, restricted cash, student contracts receivable, accounts payable and accrued expenses to approximate fair value due to the short maturity of these instruments.

Segment Reporting [Abstract]
Segments	Segments The Trust defines business segments by their distinct customer base and service provided. The Trust has identified three reportable segments: collegiate housing leasing, development consulting services and management services. Management evaluates each segment’s performance based on net operating income, which is defined as income before depreciation, amortization, ground leases, impairment losses, interest expense (income), gains (losses) on extinguishment of debt, equity in earnings of unconsolidated entities and noncontrolling interests.

Summary of significant accoun23

Summary of significant accounting policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying condensed consolidated financial statements have been prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States (“GAAP”).
Principles of consolidation	The accompanying condensed consolidated financial statements of the Trust represent the assets and liabilities and operating results of the Trust and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying condensed consolidated financial statements. Principles of consolidation The Trust evaluates its interest in partnerships, joint ventures and other similar entities under the variable interest entity (“VIE”) guidance. Under the VIE model, the Trust consolidates an entity when it has control to direct the activities of the VIE and where it is determined to be the primary beneficiary. If it is determined that the legal entity qualifies for a VIE scope exception or the legal entity is not subject to the VIE model, the voting interest model is applied. Under the voting interest model, the Trust consolidates an entity when it controls the entity through the ownership of a majority voting interest. All of the Trust's property ownership, development and related business operations are conducted through the Operating Partnership. See the assets and liabilities of the Operating Partnership in the accompanying condensed consolidated financial statements.
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Collegiate housing properties	Collegiate housing properties Land, land improvements, buildings and improvements, and furniture, fixtures and equipment are recorded at cost. Buildings and improvements are depreciated over 15 to 40 years, land improvements are depreciated over 15 years and furniture, fixtures and equipment are depreciated over 3 to 7 years. Depreciation is computed using the straight-line method for financial reporting purposes over the estimated useful life. The Trust capitalizes interest based on the weighted average interest cost of the total debt and internal development costs while developments are ongoing as assets under development. When the property opens, these costs, along with other direct costs of the development, are transferred into the applicable asset category and depreciation commences. Acquired collegiate housing communities’ results of operations are included in the Trust’s results of operations from the respective dates of acquisition. Appraisals, estimates of cash flows and other valuation techniques are used to allocate the purchase price of acquired property between land, land improvements, buildings and improvements, furniture, fixtures and equipment and identifiable intangibles, such as amounts related to in-place leases. Acquisition costs are expensed as incurred for acquisitions completed prior to the adoption of Accounting Standards Update ("ASU") 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business" ("ASU 2017-01") and are included in general and administrative expenses in the accompanying condensed consolidated statements of income and comprehensive income. The Trust adopted ASU 2017-01 prospectively on January 1, 2017. Acquisition costs have been capitalized for subsequent acquisitions that are not deemed to be business combinations. Management assesses impairment of long-lived assets to be held and used whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Management uses an estimate of future undiscounted cash flows of the related asset based on its intended use to determine whether the carrying value is recoverable. If the Trust determines that the carrying value of an asset is not recoverable, the fair value of the asset is estimated and an impairment loss is recorded to the extent the carrying value exceeds estimated fair value. Management estimates fair value using discounted cash flow models, market appraisals if available and other market participant data. During the six months ended June 30, 2017 and 2016 , there were no impairment losses recognized. When a collegiate housing community has met the criteria to be classified as held for sale, the fair value less cost to sell such asset is estimated. If the fair value less cost to sell the asset is less than the carrying amount of the asset, an impairment charge is recorded for the estimated loss. Depreciation expense is no longer recorded once a collegiate housing community has met the held for sale criteria. Dispositions that represent a strategic shift in the business will qualify for treatment as discontinued operations. The property disposition during the six months ended June 30, 2017 did not qualify for treatment as discontinued operations and, as a result, the operations of the property are included in continuing operations in the accompanying condensed consolidated statements of income and comprehensive income.
Redeemable noncontrolling interests (the Trust) / redeemable limited partners (EROP)	Redeemable noncontrolling interests (the Trust) / redeemable limited partners (EROP) The Trust follows the guidance issued by the Financial Accounting Standards Board ("FASB") regarding the classification and measurement of redeemable securities. The Trust classifies redeemable noncontrolling interests, which include redeemable interests in consolidated joint ventures with puts exercisable by the joint venture partners and units of limited partnership interest in University Towers Operating Partnership, LP and in the Operating Partnership in the mezzanine section of the accompanying condensed consolidated balance sheets. The Trust accounts for certain noncontrolling interests with embedded put and call features with fixed exercise prices and exercise dates as a financing arrangement, and these amounts are recorded as accrued liabilities in the accompanying condensed consolidated balance sheets. The liability is initially measured at present value of the fixed price settlement amount. Subsequently, the liability is accreted to the fixed price over the term of the contract, with the resulting expense recognized as interest expense. The Trust also has certain noncontrolling interests with put options at substantially fixed prices. These noncontrolling interests are accounted for as noncontrolling interests redeemable at other than fair value. The Trust accounts for the change in redemption value through the use of an accretion model from the date of inception to the expected redemption date. Changes in redemption value are recorded in equity, either through retained earnings or additional paid-in capital (absent any retained earnings). The impact of the changes in redemption value (accretion) is included in earnings per share using the two-class method. In the accompanying condensed consolidated balance sheets of the Operating Partnership, the redeemable units of limited partnership in the Operating Partnership are classified as redeemable limited partners, and the redeemable interests in consolidated joint ventures with puts exercisable by the joint venture partners and units of limited partnership interest in University Towers Operating Partnership, LP are classified as redeemable noncontrolling interests. The redeemable noncontrolling interests / redeemable limited partner units are adjusted to the greater of carrying value or fair market value based on the price per share of EdR's common stock or redemption value at the end of each respective reporting period.
Common stock issuances and offering costs	Common stock issuances and offering costs Specific incremental costs directly attributable to the issuance of EdR common stock are charged against the gross proceeds of the related issuance. Accordingly, underwriting commissions and other stock issuance costs are reflected as a reduction of additional paid-in capital in the accompanying condensed consolidated statements of changes in equity. The Trust is structured as an umbrella partnership REIT ("UPREIT") and contributes all proceeds from its various equity offerings to EROP. For every one share of common stock offered and sold by EdR for cash, EdR must contribute the net proceeds to EROP and, in return, EROP will issue one OP Unit to EdR.
Income taxes	Income taxes EdR qualifies as a REIT under the Internal Revenue Code of 1986, as amended (the "Code"). EdR is generally not subject to federal, state and local income taxes on any of its taxable income that it distributes if it distributes at least 90% of its REIT taxable income for each tax year to its stockholders and meets certain other requirements. If EdR fails to qualify as a REIT for any taxable year, EdR will be subject to federal, state and local income taxes (including any applicable alternative minimum tax) on its taxable income. The Trust has elected to treat certain of its subsidiaries, including the Management Company, as TRSs. A TRS is subject to federal, state and local income taxes. The Management Company provides management services and through the Development Company, provides development services, which if directly provided by the Trust would jeopardize EdR’s REIT status. Deferred tax assets and liabilities are recognized based on the difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect in the years in which those temporary differences are expected to reverse. The Trust had no unrecognized tax benefits as of June 30, 2017 and December 31, 2016 . The Trust and its subsidiaries file federal and state income tax returns. As of June 30, 2017 , open tax years generally included tax years for 2013, 2014, 2015 and 2016. The Trust’s policy is to include interest and penalties related to unrecognized tax benefits in general and administrative expenses.
Goodwill and other intangible assets	Goodwill and other intangible assets Goodwill is tested annually for impairment as of December 31, and is tested for impairment more frequently if events and circumstances indicate that the carrying value of the assets might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. The accumulated impairment loss recorded is $0.4 million . No additional impairment has been recorded through June 30, 2017 . The carrying value of goodwill was $3.1 million as of June 30, 2017 and December 31, 2016 , of which $2.1 million was recorded on the management services reportable segment and $0.9 million was recorded on the development consulting services reportable segment. Goodwill is not subject to amortization. Other intangible assets generally include in-place leases acquired in connection with acquisitions of collegiate housing properties. As of June 30, 2017 and December 31, 2016 , gross in-place leases totaled $12.2 million and $7.4 million , respectively, and are being amortized over the life of the remaining lease term, which is generally less than one year.
Investment in unconsolidated entities	Investment in unconsolidated entities The Trust accounts for its investments in unconsolidated joint ventures using the equity method whereby the costs of an investment are adjusted for the Trust’s share of earnings of the respective investment reduced by distributions received. The earnings and distributions of the unconsolidated joint ventures are allocated based on each owner’s respective ownership interests. These investments are classified as other assets or accrued expenses, depending on whether the distributions exceed the Trust’s contributions and share of earnings in the joint ventures, in the accompanying condensed consolidated balance sheets (see Note 5).
Earnings per share	Earnings per share Earnings per Share - The Trust Basic earnings per share is calculated by dividing net income available to common stockholders after accretion of redeemable noncontrolling interests by weighted average shares of common stock outstanding, including outstanding units in the Operating Partnership designated as LTIP Units ("LTIP Units"). Diluted earnings per share is calculated similarly, except that it includes the dilutive effect of the assumed exercise of potentially dilutive securities and the shares issuable upon settlement of the Forward Agreements using the treasury stock method. The Trust follows the authoritative guidance regarding the determination of whether certain instruments are participating securities. All unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are included in the computation of earnings per share under the two-class method. This results in shares of unvested restricted stock and LTIP Units being included in the computation of basic earnings per share for all periods presented. When noncontrolling interests are redeemable at other than fair value, increases or decreases in the carrying amount of the redeemable noncontrolling interests are reflected in earnings per share using the two-class method. Earnings per OP Unit - EROP Basic earnings per unit is calculated by dividing net income available to unitholders after accretion of redeemable noncontrolling interests by the weighted average number of OP Units and LTIP Units outstanding. Diluted earnings per unit is calculated similarly, except that it includes the dilutive effect of the assumed exercise of potentially dilutive securities and the shares issuable upon settlement of the Forward Agreements using the treasury stock method. EROP follows the authoritative guidance regarding the determination of whether certain instruments are participating securities.
Recent accounting pronouncements	Recent accounting pronouncements In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" ("ASU 2016-18"). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and restricted cash. Therefore, amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows, and transfers between cash and cash equivalents and restricted cash are no longer presented within the statement of cash flows. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. The Trust anticipates retrospectively adopting this guidance on January 1, 2018. The Trust's initial analysis indicates the adoption of this ASU will result in the change in restricted cash to no longer be presented in the statement of cash flows as an investing cash flow. In August 2016, the FASB issued ASU 2016-15, " Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments " ("ASU 2016-15"). ASU 2016-15 addresses eight specific cash flow issues and intends to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows and will be applied retrospectively. This guidance is effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period, with early adoption permitted. The Trust adopted ASU 2016-15 effective January 1, 2017. As a result of this adoption, there was no impact to the condensed consolidated statements of cash flows for either period presented. In February 2016, the FASB issued ASU 2016-02, " Leases (Topic 842)" ("ASU 2016-02"), which requires a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years, on a modified prospective basis. The Trust's primary revenue is collegiate housing rental income; as such, the Trust is a lessor on a significant number of leases. The Trust is continuing to evaluate the potential impact of the ASU and believes it will continue to account for its leases in substantially the same manner due to the short-term nature (less than 12 months) of the leases. The most significant change for the Trust relates to ground lease agreements, which could result in recording the right-of-use asset and related liability on the balance sheet. The Trust plans to adopt ASU 2016-02 effective January 1, 2019 and is continuing to evaluate and quantify the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, " Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"), as amended by ASU 2015-04 to defer the effective date. The guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including the guidance on real estate derecognition for most transactions. ASU 2014-09 provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years and permits the use of either the retrospective or cumulative effect transition method. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. Since the issuance of ASU 2014-09, the FASB has issued ASU 2016-08 that is intended to improve the understandability of the implementation guidance regarding principal versus agent considerations and has issued ASU 2016-10 to clarify the identification of performance obligations and the implementation guidance related to licensing. The effective dates of these amendments are the same as ASU 2014-09. The Trust does not expect the adoption of this standard to have a material impact on its consolidated financial statements, as a substantial portion of its revenue consists of rental income from leasing arrangements, which is specifically excluded from this ASU. The Trust's initial analysis of its non-lease related revenue contracts, which comprise less than 15% of consolidated revenues, indicates the adoption of this ASU will not have a material effect on the consolidated financial statements; however, the Trust is still in the process of evaluating this ASU.
Fair value of financial instruments	The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions used to value the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined in ASC 820, Fair Value Measurements and Disclosures ("ASC 820") as follows: • Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2 - Observable inputs other than those included in Level 1, for example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets. • Level 3 - Unobservable inputs reflecting management's own assumption about the inputs used in pricing the asset or liability at the measurement date. Non-financial assets measured at fair value on a nonrecurring basis consist of real estate assets and investments in partially owned entities that have been written-down to estimated fair value when it has been determined that asset values are not recoverable. Fair value is estimated relating to impairment assessments based upon an income capitalization approach (which considers prevailing market capitalization rates and operations of the community) or the negotiated sales price, if applicable. Based upon the inputs used to value properties under the income capitalization approach, valuations under this method are classified within Level 3 of the fair value hierarchy. For the communities for which the estimated fair value was based on negotiated sales prices, the valuation is classified within Level 2 of the fair value hierarchy.
