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 real estate investment trust ("REIT") that is publicly traded on the New York Stock Exchange under the ticker symbol "EDR." Under the Articles of Incorporation, as amended, 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 indirectly wholly-owned by EdR. As of June 30, 2015, 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 EDR Management Inc. (the “Management Company”), a Delaware corporation performing collegiate housing management activities. The Management Company has been designated as a taxable REIT subsidiary ("TRS"). Through EDR Development LLC (the “Development Company”), a Delaware limited liability company and wholly owned subsidiary of the Management Company, the Trust provides development consulting services for third party collegiate housing communities.

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. Interim financial information The accompanying unaudited interim 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, 2014, as filed with the Securities and Exchange Commission (the "SEC") on February 27, 2015. 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. Cash and cash equivalents All highly-liquid investments with a maturity of three months or less when purchased are considered cash equivalents. Restricted cash is excluded from cash for the purpose of preparing the condensed consolidated statements of cash flows. The Trust maintains cash balances in various banks. At times, the amounts of cash may exceed the amount the Federal Deposit Insurance Corporation (“FDIC”) insures. As of June 30, 2015 , the Trust had $13.5 million cash on deposit that was uninsured by the FDIC or in excess of the FDIC limits. Restricted cash Restricted cash includes resident security deposits, as required by law in certain states, and escrow accounts held by lenders for the purpose of paying taxes, insurance, principal and interest and funding capital improvements. Notes receivable On August 26, 2013, the Trust provided a $0.5 million promissory loan to College Park Apartments, Inc. ("CPA"), the Trust's partner in the unconsolidated joint venture University Village-Greensboro LLC (see Note 5), at an interest rate of 10% per annum and a maturity date of August 1, 2020. Under the loan, CPA can make one draw per calendar quarter. As of June 30, 2015 and December 31, 2014 , $0.4 million was outstanding. The loan is secured by CPA's interest in the joint venture. On March 20, 2015, the Trust provided a $1.7 million promissory loan to Concord Eastridge, Inc, the Trust's partner in the joint venture at Roosevelt Point, at an interest rate equal to 2% plus London InterBank Offered Rate ("LIBOR") per annum compounded monthly and a maturity date of March 1, 2017. The loan is secured by Concord Eastridge's interest in the joint venture. As of June 30, 2015 , $1.7 million was outstanding. 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. For assets under development, the Trust capitalizes interest and internal development costs as assets under development. Capitalized interest is determined using the weighted average interest costs of total debt. 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 and are included in general and administrative expenses in the accompanying condensed consolidated statements of income and comprehensive income. 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 three and six months ended June 30, 2014 , the Trust recorded a $9.9 million and $11.8 million loss on impairment of collegiate housing properties, respectively. The impairment losses were due to a change in circumstances that indicated the respective carrying value may not be recoverable. The change in circumstances for the property could be attributable to changes in property specific market conditions, changes in anticipated future use and/or leasing results or a combination of these factors. 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. Only dispositions that represent a strategic shift in the business will qualify for treatment as discontinued operations. The two property dispositions during the six months ended June 30, 2014 did not qualify for treatment as discontinued operations. 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 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. 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. The redeemable noncontrolling interest units / redeemable limited partner units are adjusted to the greater of carrying value or fair market value based on the common share price of EdR 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 statement 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. During October 2014, the Trust entered into agreements to establish an at-the-market equity offering program ("ATM Program") authorized to sell a maximum of $150.0 million in additional shares of EdR common stock. The Trust sold 0.3 million shares under these distribution agreements during the six months ended June 30, 2015 and received net proceeds of $10.6 million . The Trust used the net proceeds to repay debt, fund its development pipeline and for general corporate purposes. On November 20, 2014, the Board authorized a 1-for-3 reverse stock split of shares of EdR common stock, effective December 1, 2014. On April 30, 2015, the Operating Partnership entered into a Second Amended and Restated Agreement of Limited Partnership, which reduced the number of units of limited partnership of the Operating Partnership (the "OP Units") outstanding as a result of the 1-for-3 reverse stock split the Trust completed in December 2014. Accordingly, every three issued and outstanding shares of EdR common stock and OP Units prior to the split were reduced to one. All shares and units and related per-share and per-unit information presented in these financial statements for periods prior to the effective date have been retroactively adjusted to reflect the decreased number of shares and OP Units. Debt premiums Differences between the estimated fair value of debt and the principal value of debt assumed in connection with collegiate housing property acquisitions are amortized over the term of the related debt as an offset to interest expense using the effective interest method. As of June 30, 2015 and December 31, 2014 , net unamortized debt premiums totaled $1.1 million and $1.5 million , respectively. These amounts are included in mortgage and construction loans in the accompanying condensed consolidated balance sheets. 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. Goodwill and other intangible assets Goodwill is not subject to amortization, but is tested annually for impairment as of December 31, and is tested for impairment more frequently if events and circumstances indicate that 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 as of December 31, 2008 was $0.4 million . No additional impairment has been recorded through June 30, 2015 . The carrying value of goodwill was $3.1 million as of June 30, 2015 and December 31, 2014 , of which $2.1 million was recorded on the management services segment and $0.9 million was recorded on the development consulting services segment. Other intangible assets generally include in-place leases acquired in connection with acquisitions and are amortized over the estimated life of the lease/contract term. The carrying value of other intangible assets was $0.1 million and $0.4 million as of June 30, 2015 and December 31, 2014 , 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). Stock-based compensation On May 4, 2011, the Trust’s stockholders approved the Education Realty Trust, Inc. 2011 Omnibus Equity Incentive Plan (the “2011 Plan”). The 2011 Plan replaced the Education Realty Trust, Inc. 2004 Incentive Plan (“2004 Plan”) in its entirety. The 2011 Plan is described more fully in Note 9. Compensation costs related to share-based payments are recognized in the accompanying condensed consolidated financial statements in accordance with authoritative guidance. Earnings per share Earnings per Share - The Trust Basic earnings per share is calculated by dividing net earnings available to common stockholders 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. 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. Earnings per OP Unit - EROP Basic earnings per unit is calculated by dividing net earnings available to unitholders 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. EROP follows the authoritative guidance regarding the determination of whether certain instruments are participating securities. Fair value measurements The Trust follows the guidance contained in FASB Accounting Standards Codification 820, Fair Value Measurements and Disclosures ("ASC 820"). Fair value is generally defined as the exit price at which an asset or liability could be exchanged in a current transaction between willing unrelated parties, other than in a forced liquidation or sale. ASC 820 establishes a fair value hierarchy, giving the highest priority to quoted prices in active markets and the lowest priority to unobservable data, and requires disclosures for assets and liabilities measured at fair value based on their level in the hierarchy. 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 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. Derivative instruments and hedging activities All derivative financial instruments are recorded on the balance sheet at fair value. Changes in fair value are recognized either in earnings or as other comprehensive income (loss), depending on whether the derivative has been designated as a fair value or cash flow hedge and whether it qualifies as part of a hedging relationship, the nature of the exposure being hedged, and how effective the derivative is at offsetting movements in underlying exposure. Hedge accounting is discontinued when it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item; the derivative expires or is sold, terminated, or exercised; it is no longer probable that the forecasted transaction will occur; or management determines that designating the derivative as a hedging instrument is no longer appropriate. The Trust uses interest rate swaps to effectively convert a portion of its variable rate debt to fixed rate, thus reducing the impact of changes in interest rates on interest payments (see Notes 6 and 10). These instruments are designated as cash flow hedges and the interest differential to be paid or received is recorded as interest expense. Recent accounting pronouncements In April 2015, the FASB issued ASU 2015-03, " Interest - Imputation of Interest (Subtopic 835-30) " ("ASU 2015-03"). ASU 2015-03 simplifies the presentation of debt issuance costs and requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs would not be affected by the amendments in ASU 2015-03. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those fiscal years, with retrospective application required. The Trust is currently evaluating the provisions of this guidance. In February 2015, the FASB issued ASU 2015-02, " Consolidation (Topic 810) " ("ASU 2015-02"), which amends the consolidation requirements in ASC 810, Consolidation . ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments: (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidated analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships and (iv) provide a scope exception for certain entities. ASU 2015-02 is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those fiscal years and permits the use of either the retrospective or cumulative effect transition method. The Trust is currently evaluating the provisions of this guidance. In May 2014, the FASB issued ASU 2014-09, " Revenue from Contracts with Customers (Topic 606) " ("ASU 2014-09"). 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. The Trust is currently evaluating the provisions of this guidance.

Real Estate [Abstract]
Acquisition and development of real estate investments	Acquisition and development of real estate investments Acquisition of collegiate housing properties 2015 Acquisition On June 16, 2015, the Trust completed the acquisition of The Commons on Bridge with 51 apartment units consisting of 150 beds serving the University of Tennessee in Knoxville, Tennessee for a contract price of $9.7 million . The acquisition was funded from draws on the Fifth Amended Revolver (as defined in Note 6). Acquisition costs of $0.1 million were incurred related to this transaction. Due to the timing of the completion of acquisition, work is still ongoing to determine the fair value of the assets and liabilities of The Commons on Bridge as of the acquisition date. Below is a preliminary allocation of the purchase price to the fair values of assets acquired and liabilities assumed as of the date of acquisition (in thousands): Collegiate housing properties $ 9,624 In-place leases 76 Other assets 5 Current liabilities (338 ) Total net assets acquired $ 9,367 The $0.3 million difference between contracted price of $9.7 million and the net assets above represents working capital and other liabilities that were not part of the contractual purchase price, but were acquired. The unaudited pro forma information had the acquisition date been January 1, 2014 is as follows (in thousands, except per share and per unit amounts): Six months ended June 30, 2015 2014 Total revenue $ 121,974 $ 105,131 Net income attributable to the Trust $ 10,108 $ 3,415 Net income attributable to common shareholders - basic and diluted $ 0.21 $ 0.09 Net income attributable to EROP $ 10,160 $ 3,537 Net income attributable to unitholders - basic and diluted $ 0.21 $ 0.09 2014 Acquisitions During the year ended December 31, 2014 , the following collegiate housing property acquisitions were completed: Name Primary University Served Acquisition Date # of Beds # of Units Contract Price (in thousands) 109 Tower Florida International University Miami, Florida Aug 2014 542 149 $ 43,500 District on Apache Arizona State University Tempe, Arizona Sept 2014 900 279 $ 89,800 Combined acquisition costs for these purchases were $0.9 million . These acquisitions were funded with proceeds from the follow-on equity offering in June 2014, draws on the Fourth Amended Revolver and the Fifth Amended Revolver (see Note 6) and cash on hand. A summary follows of the fair values of the assets acquired and the liabilities assumed as of the dates of the acquisitions (in thousands): 109 Tower District on Apache Total Collegiate housing properties $ 43,384 $ 89,216 $ 132,600 In-place leases — 643 643 Other assets 200 36 236 Current liabilities (746 ) (1,341 ) (2,087 ) Total net assets acquired $ 42,838 $ 88,554 $ 131,392 The contracted purchase price of $133.3 million , reflected in the table above, net of $2.1 million in assumed liabilities, represents a net asset value of $131.2 million . The $0.2 million difference between this amount and the net assets reflected in the second table above represents working capital and other assets that were not part of the contractual purchase price, but were acquired. During 2014, the Trust also purchased the remaining 30% of its joint venture partner's interest in The Retreat at Oxford and a portion of its joint venture partner's interest in Roosevelt Point (see Note 8). The unaudited pro forma information had the acquisition date been January 1, 2013 is as follows (in thousands, except per share and per unit amounts): Six months ended June 30, 2014 Total revenue (1) $ 108,213 Net income attributable to the Trust (1) $ 4,161 Net income attributable to common shareholders - basic and diluted $ 0.11 Net income attributable to EROP (1) $ 4,287 Net income attributable to unitholders - basic and diluted $ 0.11 (1) As the 109 Tower opened for 2014/2015 lease year, the supplemental proforma revenue and net income for the period January 1, 2014 - June 30, 2014 only includes the District on Apache. Development of collegiate housing properties During 2014 , the Trust developed the following communities which opened during the 2014/2015 lease year.

The Trust developed additional housing on the existing land, which opened for the 2014/2015 lease year. (2) In December 2011, the Trust was selected by the University of Kentucky to develop, own and manage new collegiate housing on its campus. This project will be financed through the ONE Plan SM . Phase I opened in August 2013 and Phase II, which includes these communities, opened for the 2014-2015 lease year. The third phase is under development. (3) In March 2013, the Trust announced an agreement with Javelin 19 Investments, LLC ("Javelin 19") to develop, own and manage 605 West, a new collegiate housing property near Duke University. The Trust is the majority owner and managing member of the joint venture and manages the community, which opened in August 2014. For a period of five years from the date on which the property receives its initial certificate of occupancy, Javelin 19 has the right to require the Trust to purchase Javelin 19’s 10% interest in the joint venture at a price to be determined. (4) In 2010, LeylandAlliance LLC and the Trust entered into an agreement to develop the first two phases of Storrs Center, a mixed-use town center project, adjacent to the University of Connecticut. The Trust developed, owns and manages the collegiate housing properties in these first two phases and both phases include commercial and residential offerings. The first phase opened in August 2012 and the second phase opened in August 2013. LeylandAlliance LLC and the Trust subsequently entered into additional agreements to develop the third and fourth phases of the project. The third phase opened in August 2014 and the fourth phase is under development. (5) In 2012, Trust entered into an agreement to develop, own and manage a mixed-use development located two blocks from University of Minnesota.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies 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 agreement, the joint venture partner 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 is 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, 2015 December 31, 2014 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 % $ 23,471 n/a $ 5,868 n/a $ 23,643 n/a $ 5,911 n/a The Marshall 50 % 56,270 8,767 28,135 4,384 55,663 8,767 27,832 4,384 Georgia Heights 50 % 22,082 7,230 11,041 3,615 — 7,230 — 3,615 In connection with the development agreement entered into on July 14, 2010 for a project at the Science + Technology Park at Johns Hopkins Medical Institute, the Trust committed to provide a guarantee of repayment of a $42.0 million third-party construction loan for a $3.0 million fee, of which the carrying value approximated fair value. On July 1, 2014, the third-party owners refinanced the construction loan and the Trust was released from the guarantee obligations. The Trust collected and recognized the $3.0 million guarantee fee during the third quarter of 2014. 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 (see Note 3). The Operating Partnership and LeylandAlliance LLC jointly committed to provide a guarantee of repayment for the construction loan. As of June 30, 2015 , $23.3 million had been drawn on the construction loan, of which $4.4 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. During the six months ended June 30, 2015, an arbitration proceeding was filed against a subsidiary of the Trust and a companion federal suit was filed against the Trust itself, both actions related to a change order dispute by the general contractor on a completed third-party development project. The general contractor is seeking damages in the amount of $1.6 million plus attorney and other fees. The Trust believes it has meritorious defenses and viable counterclaims against the general contractor. At this time, the Trust cannot predict the outcome of these claims as the matter is in its initial stages. Accordingly, no amounts have been accrued in the Trust’s condensed consolidated financial statements for these claims. 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 our financial position, results of operations or liquidity. Under the terms of the limited partnership agreement of University Towers Operating Partnership, LP, so long as the contributing owners of such property hold at least 25% of the University Towers Partnership Units, the Trust has agreed to maintain certain minimum amounts of debt on the property to avoid triggering gain to the contributing owners. If the Trust fails to do this, the Trust must repay the contributing owners the amount of taxes they incur. After being awarded a development consulting contract, the Trust will enter into predevelopment consulting contracts with educational institutions to develop collegiate housing communities on their behalf. The Trust will enter into reimbursement agreements that provide for the Trust to be reimbursed for the predevelopment costs incurred prior to the institution’s governing body formally approving the final development contract. As of June 30, 2015 and December 31, 2014 , the Trust had reimbursable predevelopment costs of $1.8 million and $1.7 million , respectively, which are reflected in other assets in the accompanying condensed consolidated balance sheets.

The purpose of the 2011 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 2011 Plan replaced the Education Realty Trust, Inc. 2004 Incentive Plan in its entirety and authorizes the grant of the 105,000 shares that remained available for grant under the 2004 plan, as well as 1,049,167 additional shares. As of June 30, 2015 , the Trust had 652,356 shares of its common stock reserved for issuance pursuant to the 2011 Plan.

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. Restricted stock is generally taxed at the time of vesting. As of June 30, 2015 and December 31, 2014 , unearned compensation related to restricted stock totaled $0.5 million and $0.6 million , respectively, and will be recorded as expense over the applicable vesting period. The value is determined based on the market value of the Trust’s common stock on the grant date. During the six months ended June 30, 2015 and 2014 , compensation expense of $0.2 million and $0.4 million , respectively, was recognized in the accompanying condensed consolidated statements of income and comprehensive income, related to the vesting of restricted stock. During the three months ended June 30, 2015 and 2014 , compensation expense of $0.1 million and $0.2 million , respectively, was recognized in the accompanying condensed consolidated statements of income and comprehensive income, related to the vesting of restricted stock. Effective January 1, 2014, the Trust adopted the 2014 Long-Term Incentive Plan (the "2014 LTIP"). The purpose of the 2014 LTIP is to attract, retain and motivate the executive officers and certain key employees of the Trust to promote the long-term growth and profitability of the Trust. On January 1, 2014, the Trust issued 24,742 time vested restricted stock to executives and key employees under the 2014 LTIP. Additional shares were issued in August 2014 pursuant to the 2014 LTIP. The restricted stock granted under the 2014 LTIP will vest ratably over three years as long as the participants remain employed by the Trust. 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 Performance Period, the compensation committee of the Board 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 the Trust’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. On January 1, 2014, the Trust granted 102,297 performance vested RSUs to executives and key employees under the 2014 LTIP described above. As of June 30, 2015 and December 31, 2014 , unearned compensation related to RSUs totaled $1.1 million and $1.5 million , respectively, and will be recorded as expense over the applicable vesting period. The value was determined using a Monte Carlo simulation technique. During the six months ended June 30, 2015 and 2014 , compensation expense of $0.4 million and $0.6 million , respectively, was recognized in the accompanying condensed consolidated statements of income and comprehensive income, related to the vesting of RSUs. During the three months ended June 30, 2015 and 2014 , compensation expense of $0.2 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. On January 1, 2015, 8,754 fully-vested shares of common stock were issued pursuant to the vesting of RSUs granted in 2012. On February 4, 2015, the compensation committee approved the structure, including the awards, for the 2015 Long-Term Incentive Plan (the “2015 LTIP”). The 2015 LTIP differs in two respects from the prior plans: (i) the participants have elected to receive LTIP Units in the Operating Partnership instead of time restricted stock or RSUs; and (ii) the performance criteria for the performance based award has been revamped to measure the Trust's performance based on a mixture of objective internal achievement goals and relative performance against its industry peers and other REITs. Under the 2015 LTIP, 155,778 LTIP Units were issued to the participants. The 2015 LTIP provides that 25% of a participant’s award consists of a time-vested grant of LTIP Units 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 under the 2014 LTIP, the time-vested 2015 LTIP Units vest over a three -year period and are valued for award purposes at a value equal to the price of the Trust's stock on the grant date. The time-vested 2015 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 2015 LTIP Units. Similar to the 2014 LTIP, the vesting of performance-based 2015 LTIP Units is dependent upon the Trust's achievement of six performance criteria approved by the 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. 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 will be assessed quarterly. The performance-based 2015 LTIP Units are entitled to voting and distribution rights from the effective date of the grant in accordance with the operating agreement of the Operating Partnership, but are non-transferable and non-convertible until fully vested. After the determination of the achievement of the performance criteria, any performance-based 2015 LTIP Units that were awarded but did not become vested LTIP Units will be canceled. Once fully vested, the 2015 LTIP Units may be converted to OP Units in the Operating Partnership and thereafter, at the election of the unitholder, redeemable into shares of EdR’s stock or cash, at the discretion of the general partner, in accordance with the terms of the Partnership Agreement. Compensation expense recognized in general and administrative expense in the accompanying condensed consolidated statement of income and comprehensive income related to the LTIP Units was $0.2 million and $0.4 million for the three and six months ended June 30, 2015 , respectively. As of June 30, 2015 , unearned compensation related to LTIP Units totaled $2.6 million , and will be recorded as expense over the applicable vesting period. Total stock-based compensation recognized in general and administrative expense in the accompanying condensed consolidated statements of income and comprehensive income for the six months ended June 30, 2015 and 2014 was $1.1 million and $1.1 million , respectively. Total stock-based compensation recognized in general and administrative expense in the accompanying condensed consolidated statements of income and comprehensive income for the three months ended June 30, 2015 and 2014 was $0.6 million and $0.5 million , respectively. A summary of the stock-based incentive plan activity as of and for the six months ended June 30, 2015 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, 2014 46,810 (1) $ 27.94 146,911 $ 20.58 — $ — Granted — — — — 155,778 18.83 Vested (17,774 ) 27.76 — (2) — — — Surrendered (3,467 ) 29.72 — — — — Outstanding as of June 30, 2015 25,569 (1) $ 28.32 146,911 $ 20.58 155,778 $ 18.83 (1) Represents unvested shares of restricted stock awards as of the date indicated. (2) On January 1, 2012, the Trust granted a total of $1.1 million of performance vesting RSUs that were denominated in cash and converted into common stock at the end of the performance period to executives and key employees under the 2012 LTIP. On January 1, 2015, the Trust issued 8,754 shares of common stock related to the vesting of the RSUs under the 2012 LTIP.

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, 2015 and 2014, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. As of June 30, 2015 , 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. 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 $3.2 million is estimated to be reclassified to earnings as an increase to interest expense. As of June 30, 2015 and December 31, 2014 , the fair value of the derivatives is a liability of $4.8 million and $4.5 million , respectively, and is included in accrued expenses in the accompanying condensed consolidated balance sheets. 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, 2015 and 2014 (in thousands): Derivatives in Cash Flow Hedging Relationships Amount of 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) 2015 Interest rate contracts $ (2,136 ) Interest expense $ 1,788 2014 Interest rate contracts $ (4,667 ) Interest expense $ 910 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, 2015 and 2014 (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) 2015 Interest rate contracts $ 1,195 Interest expense $ 897 2014 Interest rate contracts $ (3,304 ) Interest expense $ 910 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 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, 2015 and December 31, 2014 , the fair value of derivatives related to these agreements, which includes accrued interest, but excludes any adjustment for nonperformance risk, was a liability of $5.1 million and $4.7 million , respectively. As of June 30, 2015 , 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, 2015 , it could have been required to settle its obligations under the agreements at their termination value of $5.1 million .

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments 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, 2014 and has remained on the accompanying condensed consolidated balance sheet as of June 30, 2015 . The asset was written down to $15.1 million and the valuation was classified within Level 2 of the fair value hierarchy. As discussed in Note 10, 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 of the Trust's derivatives held as of June 30, 2015 and December 31, 2014 were classified as Level 2 of the fair value hierarchy. The table below presents the assets and liabilities measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014 , 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, 2015 and December 31, 2014 (in thousands): Estimated Fair Value Carrying value Level 1 Level 2 Level 3 June 30, 2015: Derivative financial instruments (liability position) $ 4,813 $ — $ 4,813 $ — Deferred compensation plan assets 365 365 — — December 31, 2014: Derivative financial instruments (liability position) $ 4,465 $ — $ 4,465 $ — Deferred compensation plan assets 520 520 — — 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 our unsecured revolving credit facility, unsecured term loan facility and variable rate mortgage and construction loans bear interest at variable rates, carrying value approximates the fair value. The table below summarizes the carrying amounts and fair values of these financial instruments as of June 30, 2015 and December 31, 2014 (in thousands): June 30, 2015 Estimated Fair Value Carrying value Level 1 Level 2 Level 3 Notes receivable $ 2,092 $ — $ 2,033 $ — Senior unsecured notes 250,000 — 250,941 — Unsecured revolving credit facility 138,000 — 138,000 — Unsecured term loan facility 187,500 — 187,500 — Variable rate mortgage and construction loans 84,595 — 84,595 — Fixed rate mortgage and construction loans 139,027 — 155,414 — December 31, 2014 Estimated Fair Value Carrying value Level 1 Level 2 Level 3 Notes receivable $ 375 $ — $ 318 $ — Senior unsecured notes 250,000 — 234,583 — Unsecured revolving credit facility 24,000 — 24,000 — Unsecured term loan facility 187,500 — 187,500 — Variable rate mortgage and construction loans 107,882 — 107,882 — Fixed rate mortgage and construction loans 140,270 — 154,542 — 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. The carrying value of restricted cash approximates its fair value based on the nature of our assessment of the ability to recover these amounts.

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. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intercompany fees are reflected at the contractually stipulated amounts. The following table represents the Trust’s segment information for the three and six months ended June 30, 2015 and 2014 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Collegiate Housing Leasing: Collegiate housing leasing revenue $ 53,734 $ 46,309 $ 114,117 $ 97,020 Collegiate housing leasing operations 22,868 20,975 47,008 43,143 Net operating income $ 30,866 $ 25,334 $ 67,109 $ 53,877 Total segment assets at end of period (1) $ 1,813,219 $ 1,593,035 $ 1,813,219 $ 1,593,035 Development Consulting Services: Third-party development consulting services $ 444 $ 757 $ 1,041 $ 1,559 General and administrative 878 620 1,712 1,229 Net operating income (loss) $ (434 ) $ 137 $ (671 ) $ 330 Total segment assets at end of period (2) $ 5,828 $ 4,958 $ 5,828 $ 4,958 Management Services: Third-party management services $ 780 $ 786 $ 1,833 $ 1,804 General and administrative 685 636 1,470 1,303 Net operating income $ 95 $ 150 $ 363 $ 501 Total segment assets at end of period (2) $ 9,981 $ 10,862 $ 9,981 $ 10,862 Reconciliations: Segment revenue $ 54,958 $ 47,852 $ 116,991 $ 100,383 Operating expense reimbursements 2,366 2,188 4,462 4,202 Total segment revenues $ 57,324 $ 50,040 $ 121,453 $ 104,585 Segment operating expenses $ 24,431 $ 22,231 $ 50,190 $ 45,675 Reimbursable operating expenses 2,366 2,188 4,462 4,202 Total segment operating expenses $ 26,797 $ 24,419 $ 54,652 $ 49,877 Segment net operating income $ 30,527 $ 25,621 $ 66,801 $ 54,708 Other unallocated general and administrative expenses (3,503 ) (3,010 ) (7,225 ) (6,193 ) Depreciation and amortization (15,911 ) (14,458 ) (31,777 ) (28,241 ) Ground lease (2,170 ) (1,934 ) (5,018 ) (3,833 ) Loss on impairment of collegiate housing properties — (9,870 ) — (11,780 ) Interest expense (5,451 ) (4,967 ) (11,392 ) (10,568 ) Amortization of deferred financing costs (491 ) (514 ) (1,007 ) (1,017 ) Interest income 67 41 105 111 Loss on extinguishment of debt — — — (649 ) Equity in losses of unconsolidated entities (202 ) (112 ) (396 ) (134 ) Income (loss) before income taxes and gain on sale of collegiate housing properties $ 2,866 $ (9,203 ) $ 10,091 $ (7,596 ) (1) The increase in segment assets related to the collegiate housing segment is primarily related to the opening of seven new properties and two property acquisitions and continued development of eight communities for ownership by the Trust.

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”). 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.
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.
Cash and cash equivalents	Cash and cash equivalents All highly-liquid investments with a maturity of three months or less when purchased are considered cash equivalents. Restricted cash is excluded from cash for the purpose of preparing the condensed consolidated statements of cash flows. The Trust maintains cash balances in various banks. At times, the amounts of cash may exceed the amount the Federal Deposit Insurance Corporation (“FDIC”) insures.
Restricted cash	Restricted cash Restricted cash includes resident security deposits, as required by law in certain states, and escrow accounts held by lenders for the purpose of paying taxes, insurance, principal and interest and funding capital improvements.
Notes receivable	Notes receivable On August 26, 2013, the Trust provided a $0.5 million promissory loan to College Park Apartments, Inc. ("CPA"), the Trust's partner in the unconsolidated joint venture University Village-Greensboro LLC (see Note 5), at an interest rate of 10% per annum and a maturity date of August 1, 2020. Under the loan, CPA can make one draw per calendar quarter. As of June 30, 2015 and December 31, 2014 , $0.4 million was outstanding. The loan is secured by CPA's interest in the joint venture. On March 20, 2015, the Trust provided a $1.7 million promissory loan to Concord Eastridge, Inc, the Trust's partner in the joint venture at Roosevelt Point, at an interest rate equal to 2% plus London InterBank Offered Rate ("LIBOR") per annum compounded monthly and a maturity date of March 1, 2017. The loan is secured by Concord Eastridge's interest in the joint venture. As of June 30, 2015 , $1.7 million was outstanding.
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. For assets under development, the Trust capitalizes interest and internal development costs as assets under development. Capitalized interest is determined using the weighted average interest costs of total debt. 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 and are included in general and administrative expenses in the accompanying condensed consolidated statements of income and comprehensive income. 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 three and six months ended June 30, 2014 , the Trust recorded a $9.9 million and $11.8 million loss on impairment of collegiate housing properties, respectively. The impairment losses were due to a change in circumstances that indicated the respective carrying value may not be recoverable. The change in circumstances for the property could be attributable to changes in property specific market conditions, changes in anticipated future use and/or leasing results or a combination of these factors. 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. Only dispositions that represent a strategic shift in the business will qualify for treatment as discontinued operations. The two property dispositions during the six months ended June 30, 2014 did not qualify for treatment as discontinued operations.
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 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. 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. The redeemable noncontrolling interest units / redeemable limited partner units are adjusted to the greater of carrying value or fair market value based on the common share price of EdR 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 statement 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.
Debt premiums	Debt premiums Differences between the estimated fair value of debt and the principal value of debt assumed in connection with collegiate housing property acquisitions are amortized over the term of the related debt as an offset to interest expense using the effective interest method. As of June 30, 2015 and December 31, 2014 , net unamortized debt premiums totaled $1.1 million and $1.5 million , respectively. These amounts are included in mortgage and construction loans in the accompanying condensed consolidated balance sheets.
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.
Goodwill and other intangible assets	Goodwill and other intangible assets Goodwill is not subject to amortization, but is tested annually for impairment as of December 31, and is tested for impairment more frequently if events and circumstances indicate that 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 as of December 31, 2008 was $0.4 million . No additional impairment has been recorded through June 30, 2015 . The carrying value of goodwill was $3.1 million as of June 30, 2015 and December 31, 2014 , of which $2.1 million was recorded on the management services segment and $0.9 million was recorded on the development consulting services segment. Other intangible assets generally include in-place leases acquired in connection with acquisitions and are amortized over the estimated life of the lease/contract term.
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).
Stock based compensation	Stock-based compensation On May 4, 2011, the Trust’s stockholders approved the Education Realty Trust, Inc. 2011 Omnibus Equity Incentive Plan (the “2011 Plan”). The 2011 Plan replaced the Education Realty Trust, Inc. 2004 Incentive Plan (“2004 Plan”) in its entirety. The 2011 Plan is described more fully in Note 9. Compensation costs related to share-based payments are recognized in the accompanying condensed consolidated financial statements in accordance with authoritative guidance.
Earnings per share	Earnings per share Earnings per Share - The Trust Basic earnings per share is calculated by dividing net earnings available to common stockholders 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. 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. Earnings per OP Unit - EROP Basic earnings per unit is calculated by dividing net earnings available to unitholders 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. EROP follows the authoritative guidance regarding the determination of whether certain instruments are participating securities.
Fair value measurements	Fair value measurements The Trust follows the guidance contained in FASB Accounting Standards Codification 820, Fair Value Measurements and Disclosures ("ASC 820"). Fair value is generally defined as the exit price at which an asset or liability could be exchanged in a current transaction between willing unrelated parties, other than in a forced liquidation or sale. ASC 820 establishes a fair value hierarchy, giving the highest priority to quoted prices in active markets and the lowest priority to unobservable data, and requires disclosures for assets and liabilities measured at fair value based on their level in the hierarchy. 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 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.
Derivative instruments and hedging activities	Derivative instruments and hedging activities All derivative financial instruments are recorded on the balance sheet at fair value. Changes in fair value are recognized either in earnings or as other comprehensive income (loss), depending on whether the derivative has been designated as a fair value or cash flow hedge and whether it qualifies as part of a hedging relationship, the nature of the exposure being hedged, and how effective the derivative is at offsetting movements in underlying exposure. Hedge accounting is discontinued when it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item; the derivative expires or is sold, terminated, or exercised; it is no longer probable that the forecasted transaction will occur; or management determines that designating the derivative as a hedging instrument is no longer appropriate. The Trust uses interest rate swaps to effectively convert a portion of its variable rate debt to fixed rate, thus reducing the impact of changes in interest rates on interest payments (see Notes 6 and 10). These instruments are designated as cash flow hedges and the interest differential to be paid or received is recorded as interest expense.
Recent accounting pronouncements	Recent accounting pronouncements In April 2015, the FASB issued ASU 2015-03, " Interest - Imputation of Interest (Subtopic 835-30) " ("ASU 2015-03"). ASU 2015-03 simplifies the presentation of debt issuance costs and requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs would not be affected by the amendments in ASU 2015-03. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those fiscal years, with retrospective application required. The Trust is currently evaluating the provisions of this guidance. In February 2015, the FASB issued ASU 2015-02, " Consolidation (Topic 810) " ("ASU 2015-02"), which amends the consolidation requirements in ASC 810, Consolidation . ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments: (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidated analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships and (iv) provide a scope exception for certain entities. ASU 2015-02 is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those fiscal years and permits the use of either the retrospective or cumulative effect transition method. The Trust is currently evaluating the provisions of this guidance. In May 2014, the FASB issued ASU 2014-09, " Revenue from Contracts with Customers (Topic 606) " ("ASU 2014-09"). 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. The Trust is currently evaluating the provisions of this guidance.
