Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Principles of consolidation The accompanying condensed consolidated interim financial statements (referred to as the “Financial Statements” herein) include the accounts of Scholastic Corporation (the “Corporation”) and all wholly-owned and majority-owned subsidiaries (collectively, “Scholastic” or the “Company”). Intercompany transactions are eliminated in consolidation. The Company’s fiscal year is not a calendar year. Accordingly, references in this document to fiscal 2020 relate to the twelve-month period ending May 31, 2020. Certain reclassifications have been made to conform to the current year presentation. Interim Financial Statements The accompanying Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information, and should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended May 31, 2019 . The Financial Statements presented in this Quarterly Report on Form 10-Q are unaudited; however, in the opinion of management, the Financial Statements reflect all adjustments, consisting solely of normal, recurring adjustments, necessary for the fair presentation of the Financial Statements for the periods presented. Seasonality The Company’s Children’s Book Publishing and Distribution school-based book club and book fair channels and most of its Education businesses operate on a school-year basis; therefore, the Company’s business is highly seasonal. As a result, the Company’s revenues in the first and third quarters of the fiscal year generally are lower than its revenues in the other two fiscal quarters. Typically, school-based channels and magazine revenues are minimal in the first quarter of the fiscal year as schools are not in session. Trade sales can vary throughout the year due to varying release dates of published titles. The Company generally experiences a loss from operations in the first and third quarters of each fiscal year. Use of estimates The preparation of these Financial Statements involves the use of estimates and assumptions by management, which affects the amounts reported in the Financial Statements and accompanying notes. The Company bases its estimates on historical experience, current business factors, and various other assumptions believed to be reasonable under the circumstances, all of which are necessary, in order to form a basis for determining the carrying values of certain assets and liabilities. Actual results may differ from those estimates and assumptions. On an on-going basis, the Company evaluates the adequacy of its reserves and the estimates used in these calculations, including, but not limited to: • Accounts receivable allowance for doubtful accounts • Pension and postretirement benefit plans • Uncertain tax positions • The timing and amount of future income taxes and related deductions • Inventory reserves • Cost of goods sold from book fair operations during interim periods based on estimated gross profit rates • Sales tax contingencies • Royalty advance reserves and royalty expense accruals • Impairment testing for goodwill, intangible and other long-lived assets and investments • Assets and liabilities acquired in business combinations • Variable consideration related to anticipated returns • Allocation of transaction price to performance obligations Assets Held For Sale The Company committed to a plan to sell the company-owned facility located in Danbury, Connecticut to relocate the book fairs warehousing and distribution operations conducted in Danbury to a warehouse in Allentown, Pennsylvania. This asset is included in the Overhead segment. The Company also committed to a plan to sell the UK distribution centers located in Witney and Southam to consolidate the operations into a new facility in Warwickshire which is currently under construction. These assets are included in the International segment. The Company expects the sale of these facilities to be completed within one year and to recognize a gain on sale. The long-lived assets which consist of land, building, and building improvements are classified as held for sale. These assets are carried at the lower of carrying value or fair value less costs to sell and no additional depreciation is being recognized. As of February 29, 2020, the carrying amounts totaled $8.8 . New Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The updates in this guidance remove the following exceptions: 1. Exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); 2. Exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; 3. Exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; 4. Exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also simplifies the accounting for income taxes by: 1. Requiring an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax; 2. Requiring an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction; 3. Specifying an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements; 4. Requiring an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The guidance further provides a policy election to not allocate consolidated income taxes when a member of a consolidated tax return is not subject to income tax and provides guidance to evaluate whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. The ASU will be effective for the Company in the first quarter of fiscal 2022. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. An entity that elects to early adopt in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period and an entity that elects early adoption must adopt all the amendments in the same period. The Company is evaluating the impact of this ASU on its consolidated Financial Statements. Current Fiscal Year Adoptions Topic 842, Leases Refer to Note 11, Leases , for a discussion of the Company's lease accounting following the adoption of ASU No. 2016-02, Leases (Topic 842) in the first quarter of fiscal 2020. ASU No. 2018-15 In August 2018, the FASB issued ASU No. 2018-15, Intangibles- Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The Company adopted ASU No. 2018-15 as of the beginning of the first quarter of fiscal 2020 using the prospective approach. In the third fiscal quarter, the Company capitalized approximately $9.5 of cloud computing costs which have not yet been placed into service. This amount is included within Other assets and deferred charges within the Company's Condensed Consolidated Balance Sheets and within the operating activities section of the Company's Condensed Consolidated Statement of Cash Flows. ASU No. 2018-02 In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220)-Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The Company adopted ASU No. 2018-02 as of the beginning of the first quarter of fiscal 2020 which resulted in no impact to the Company's financial statements.

Asset Impairment Charges [Abstract]
Asset Write Down	ASSET WRITE DOWN During the third quarter, the Company implemented new systems, processes and a centralized management structure to better coordinate demand planning and procurement activity across North America, and to optimize inventory utilization and management. As a result of the foregoing, the Company determined that substantial quantities of inventory will not be required to meet future profitable demand, and will be donated, liquidated or disposed. Accordingly, a $40.0 non cash write down was recognized in the current period for this excess inventory and associated costs. The inventory cost, net of reserves, was $37.6 . In addition, $1.6 and $0.8 of author advances and prepublication costs, respectively, were written down as they were directly related to the inventory. The related impact was a loss per basic and diluted share of Class A and Common Stock of $0.84 in the three and nine month periods ended February 29, 2020 .

The loan has a maturity date of July 31, 2021. Under the agreement, the principal balance is due in full in a single payment on the last day of the term and interest on the amount borrowed is due and payable quarterly. The interest is charged at 1.77% per annum over the Base Rate. The Base Rate is currently equal to 0.75% per annum and is subject to change. As of February 29, 2020 , the Company had $2.6 outstanding on the loan. On January 24, 2020, Scholastic Limited UK entered into a term loan facility with a borrowing limit of £6.6 to fund the construction of the new UK facility. The loan has a maturity date of July 31, 2021. Under the agreement, the principal balance is due in full in a single payment on the last day of the term and interest on the amount borrowed is due and payable quarterly. The interest is charged at 1.77% per annum over the Base Rate. The Base Rate is currently equal to 0.75% per annum and is subject to change. As of February 29, 2020, the Company had $3.8 outstanding on the loan and the remaining available credit under this facility is $4.6 . US Loan Agreement On January 5, 2017, Scholastic Corporation and Scholastic Inc. (each, a “Borrower” and together, the “Borrowers”) entered into a 5-year credit facility with certain banks (the “Loan Agreement”). The Loan Agreement replaced the Company's then existing loan agreement and has substantially similar terms, except that: • the borrowing limit was reduced to $375.0 from $425.0 ; • the “starter” basket for permitted payments of dividends and other payments in respect of capital stock was increased to $275.0 from $75.0 ; and • the maturity date was extended to January 5, 2022 . The prior loan agreement, which was originally entered into in 2007 and had a maturity date of December 5, 2017 , was terminated on January 5, 2017 in connection with the entry into the new Loan Agreement and was treated as a debt modification. The Loan Agreement allows the Company to borrow, repay or prepay and reborrow at any time prior to the January 5, 2022 maturity date. Under the Loan Agreement, interest on amounts borrowed thereunder is due and payable in arrears on the last day of the interest period (defined as the period commencing on the date of the advance and ending on the last day of the period selected by the Borrower at the time each advance is made). The interest pricing under the Loan Agreement is dependent upon the Borrower’s election of a rate that is either: • A Base Rate equal to the higher of (i) the prime rate, (ii) the prevailing Federal Funds rate plus 0.50% or (iii) the Eurodollar Rate for a one month interest period plus 1% plus, in each case, an applicable spread ranging from 0.175% to 0.60% , as determined by the Company’s prevailing consolidated debt to total capital ratio. - or - • A Eurodollar Rate equal to the London interbank offered rate (LIBOR) plus an applicable spread ranging from 1.175% to 1.60% , as determined by the Company’s prevailing consolidated debt to total capital ratio. As of February 29, 2020 , the indicated spread on Base Rate Advances was 0.175% and the indicated spread on Eurodollar Advances was 1.175% , both based on the Company’s prevailing consolidated debt to total capital ratio. The Loan Agreement also provides for the payment of a facility fee in respect of the aggregate amount of revolving credit commitments ranging from 0.20% to 0.40% per annum based upon the Company’s prevailing consolidated debt to total capital ratio. At February 29, 2020 , the facility fee rate was 0.20% . A portion of the revolving credit facility, up to a maximum of $50.0 , is available for the issuance of letters of credit. In addition, a portion of the revolving credit facility, up to a maximum of $15.0 , is available for swingline loans. The Loan Agreement has an accordion feature which permits the Company, provided certain conditions are satisfied, to increase the facility by up to an additional $150.0 . As of February 29, 2020 , the Company had no outstanding borrowings under the Loan Agreement. At February 29, 2020 , the Company had open standby letters of credit totaling $5.3 issued under certain credit lines, including $ 0.4 under the Loan Agreement and $ 4.9 under the domestic credit lines discussed below. The Loan Agreement contains certain covenants, including interest coverage and leverage ratio tests and certain limitations on the amount of dividends and other distributions and the Company was in compliance with these covenants for all periods presented. Lines of Credit As of February 29, 2020 , the Company’s domestic credit lines available under unsecured money market bid rate credit lines totaled $25.0 . There were no outstanding borrowings under these credit lines as of February 29, 2020 , May 31, 2019 and February 28, 2019 . As of February 29, 2020 , availability under these unsecured money market bid rate credit lines totaled $20.1 . All loans made under these credit lines are at the sole discretion of the lender and at an interest rate and term agreed to at the time each loan is made, but not to exceed 365 days. These credit lines may be renewed, if requested by the Company, at the option of the lender. As of February 29, 2020 , the Company had various local currency credit lines totaling $25.5 underwritten by banks primarily in the United States, Canada and the United Kingdom. Outstanding borrowings under these facilities were $9.7 at February 29, 2020 at a weighted average interest rate of 4.6% , $7.3 at May 31, 2019 at a weighted average interest rate of 4.1% , and $11.0 at February 28, 2019 at a weighted average interest rate of 4.3% .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Legal Matters Various claims and lawsuits arising in the normal course of business are pending against the Company. The Company accrues a liability for such matters when it is probable that a liability exists and the amount of such liability can be reasonably estimated. When only a range can be estimated, the most probable amount in the range is accrued unless no amount within the range is a better estimate than any other amount, in which case the minimum amount in the range is accrued. Legal costs associated with litigation are expensed in the period in which they are incurred. The Company does not expect, in the case of those various claims and lawsuits arising in the normal course of business where a loss is considered probable or reasonably possible, that the reasonably possible losses from such claims and lawsuits (either individually or in the aggregate) would have a material adverse effect on the Company’s consolidated financial position or results of operations. In the third quarter, the Company entered into settlement agreements related to photo copyright infringement cases. The Company recognized $2.4 in total, of which $1.4 remained accrued as of February 29, 2020. In the first quarter, based on the status of negotiations, an alleged patent infringement claim settlement became probable and estimable. As such, an accrual of $1.5 was recognized in the Financial Statements in the first quarter of fiscal 2020. The settlement was subsequently concluded in the second quarter of fiscal 2020. Sales Tax Matters On June 21, 2018, the U.S. Supreme Court issued its opinion in South Dakota v. Wayfair, Inc. et. al., reversing prior precedent, in particular Quill Corp. v. North Dakota (1992), which held that states could not constitutionally require retailers to collect and remit sales or use taxes in respect to mail order or internet sales made to residents of a state in the absence of the retailer having a physical presence in the taxing state. As a result, the Company now has an obligation, at least on a go forward basis, based on each state's enforcement date, to collect and remit sales and use taxes, primarily in respect to sales made through its school book club channel, as well as certain sales made through its ecommerce internet sites, to residents in states that the Company had not previously remitted sales or use taxes based on having no physical presence in such states. In the majority opinion, several factors were discussed in support of the Court’s reasoning that the collection of sales and use taxes from out-of-state retailers did not constitute an undue burden on interstate commerce, including the fact that South Dakota did not require retroactive application of its statute. However, the question of retroactive application, as well as certain other factors noted in the opinion, are subject to how the states, on a state-by-state basis, interpret and apply the Court’s decision in their implementation of their respective state laws or regulations addressing the collection of sales and use taxes from out-of-state retailers. As a result, the effect of the decision on the Company depends on the positions taken by the states, on a state-by-state basis, relating to the retroactive application of the obligation to collect such taxes, as well as other factors noted in the opinion. The Company continues to monitor its compliance based on anticipated enforcement dates and an assumption as to each state's likely interpretation and application of the Court's decision. As the Company continues to monitor each state, the staggered enforcement dates, and the progress towards compliance, expenses will be incurred by the Company. As of February 29, 2020 , the Company’s school book club channel remits sales taxes in 44 states and the District of Columbia compared to 38 states and the District of Columbia in the prior fiscal year quarter ended February 28, 2019 . The Company remits sales tax to all required states. Any on-going or future litigation with states relating to sales and use taxes could be impacted favorably or unfavorably by legislative action in future fiscal periods. COVID-19 During and subsequent to the third quarter of the current fiscal year, the novel coronavirus strain, known as COVID-19, continues to spread across the globe at an increasing rate. Measures taken by governmental authorities and private actors to limit the spread of this virus may interfere with the ability of the Company's employees, suppliers, and other business providers to carry out their assigned tasks or supply materials at ordinary levels of performance relative to the conduct of the business which may cause a material curtailment to certain business operations. Moreover, as a large part of the Company's business involves sales of books and other products in schools and school facilities, as well as through school districts, if COVID-19 related measures result in widespread and lengthy school closings, the Company's consolidated results of operations and financial condition will be adversely impacted. In particular, in the context of the book fair channel, such closings may lead to cancellation of a significant number of book fairs which are not rebooked or cannot be held during the current school year and, in the context of the book clubs channel, such closings could result in a significant decrease in the participation by teacher sponsors in scheduled book club offerings. In the case of the Education segment, the last quarter of the fiscal year, currently ending May 31, 2020, is normally a significant quarter as school administrators and other educational personnel, prior to breaking for the summer, order products for immediate shipment in preparation for the following academic school year. These orders could be significantly impacted by the absence from the schools of such administrators and other educational personnel resulting from school closings. The International segment is also subject to the same risks, due to the temporary closing of English language learning centers in China, as well as disruption in the direct sales business in other parts of Southeast Asia, resulting from measures imposed to combat the spread of COVID-19.

For the nine months ended February 29, 2020 , the Company contributed $0.9 to the UK Pension Plan. The Company expects, based on actuarial calculations, to contribute cash of approximately $1.1 to the UK Pension Plan for the fiscal year ending May 31, 2020 . In the second quarter of fiscal 2019, the Company announced a change in benefits for certain postretirement benefit plan participants. Beginning January 1, 2019, the plan established Health Reimbursement Accounts (HRAs) to provide these participants with additional flexibility to choose healthcare options based on individual needs. The Company remeasured its Postretirement benefits obligation as of November 30, 2018, and recognized a reduction of $2.7 to its benefit obligation and a reduction to its accumulated comprehensive loss of $2.7 in the second quarter of fiscal 2019. The related prior service credit will be amortized as a component of Net periodic benefit cost over the average lifetime of plan participants of approximately 13.0 years .

Leases [Abstract]
Leases	The Company's lease arrangements primarily relate to corporate offices and warehouse facilities, and to a lesser extent, certain equipment and other assets. The Company's leases generally have initial terms ranging from 3 to 10 years and certain leases include renewal or early-termination options, rent escalation clauses, and/or lease incentives. Lease renewal rent payment terms generally reflect adjustments for market rates prevailing at the time of renewal. The Company's leases require fixed minimum rent payments and also often require the payment of certain other costs that do not relate specifically to its right to use an underlying leased asset, but are associated with the asset, such as real estate taxes, insurance, common area maintenance fees and/or certain other costs (referred to collectively herein as "non-lease components"), which may be fixed or variable in amount depending on the terms of the respective lease agreement. The Company's leases do not contain significant residual value guarantees or restrictive covenants. The Company determines whether an arrangement contains a lease at the inception of the arrangement. If a lease is determined to exist, the term of such lease is assessed based on the date on which the underlying asset is made available for the Company's use by the lessor. The Company's assessment of the lease term reflects the non-cancelable term of the lease, inclusive of any rent-free periods and/or periods covered by early-termination options which the Company is reasonably certain of not exercising, as well as periods covered by renewal options which the Company is reasonably certain of exercising. The Company also determines lease classification as either operating or finance at lease commencement, which governs the pattern of expense recognition and the presentation reflected in the Condensed Consolidated Statements of Operations over the lease term. For leases with a term exceeding 12 months, a lease liability is recorded on the Company's Condensed Consolidated Balance Sheet at lease commencement reflecting the present value of its fixed minimum payment obligations over the lease term. A corresponding right-of-use ("ROU") asset equal to the initial lease liability is also recorded, adjusted for any prepaid rent and/or initial direct costs incurred in connection with execution of the lease and reduced by any lease incentives received. The Company includes fixed payment obligations related to non-lease components in the measurement of ROU assets and lease liabilities, as it elects to account for lease and non-lease components together as a single lease component. ROU assets associated with finance leases are presented separate from ROU assets associated with operating leases and are included within Property, plant and equipment, net on the Company's Condensed Consolidated Balance Sheet. For purposes of measuring the present value of its fixed payment obligations for a given lease, the Company uses its incremental borrowing rate, determined based on information available at lease commencement, as rates implicit in its leasing arrangements are typically not readily determinable. The Company's incremental borrowing rate reflects the rate it would pay to borrow on a secured basis, and incorporates the term and economic environment of the associated lease. For operating leases, fixed lease payments are recognized as lease expense on a straight-line basis over the lease term. For finance leases, the initial ROU asset is depreciated on a straight-line basis over the lease term, along with recognition of interest expense associated with accretion of the lease liability, which is ultimately reduced by the related fixed payments. For leases with a term of 12 months or less (referred to as a "short-term lease"), any fixed lease payments are recognized on a straight-line basis over the lease term, and are not recognized on the Condensed Consolidated Balance Sheet. Variable lease costs for both operating and finance leases, if any, are recognized as incurred. The following table summarizes right-of-use assets and lease liabilities recorded on the Company's Condensed Consolidated Balance Sheet as of February 29, 2020 : February 29, 2020 Location within Condensed Consolidated Balance Sheet Operating leases $71.7 Operating lease right-of-use assets, net Finance leases 11.4 Property, plant and equipment, net Total lease assets $83.1 Operating leases : Current portion 22.7 Current portion of operating lease liabilities Non-current portion 52.0 Long-term operating lease liabilities Total operating lease liabilities $74.7 Finance leases : Current portion 2.1 Other accrued expenses Non-current portion 10.0 Other noncurrent liabilities Total finance lease liabilities $12.1 Total lease liabilities $86.8 The following table summarizes the activity as a result of the adoption of ASC 842 for the three and nine months ended February 29, 2020: Three Months Ended February 29, 2020 Nine Months Ended February 29, 2020 Location within Condensed Consolidated Statements of Operations Operating lease expense $7.1 $21.3 Selling, general and administrative expenses Finance lease costs : Depreciation of leased assets 0.6 1.5 Selling, general and administrative expenses Accretion of lease liabilities 0.1 0.3 Interest income (expense), net Total lease expense $7.8 $23.1 The following table summarizes certain cash flows information related to the Company's leases for the nine months ended February 29, 2020: Nine Months Ended February 29, 2020 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $3.0 Operating cash flows from finance leases 0.3 Financing cash flows from finance leases 1.5 The following table provides a maturity analysis summary of the Company's lease liabilities recorded on the Company's Condensed Consolidated Balance Sheet as of February 29, 2020 : Operating Finance Leases Leases Remainder of Fiscal 2020 (1) $7.1 $0.6 Fiscal 2021 23.6 2.5 Fiscal 2022 19.1 2.4 Fiscal 2023 13.0 2.3 Fiscal 2024 7.2 2.1 Fiscal 2025 and thereafter 11.4 3.7 Total lease payments 81.4 13.6 Less: interest (6.7) (1.5) Total lease liabilities $74.7 $12.1 (1) Fiscal 2020 includes the remaining three months of the current fiscal year ending May 31, 2020.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The Company determines the appropriate level in the fair value hierarchy for each fair value measurement of assets and liabilities carried at fair value on a recurring basis in the Company’s financial statements. The fair value hierarchy prioritizes the inputs, which refer to assumptions that market participants would use in pricing an asset or liability, based upon the highest and best use, into three levels 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 quoted prices included in Level 1, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data. • Level 3 Unobservable inputs in which there is little or no market data available, which are significant to the fair value measurement and require the Company to develop its own assumptions. The Company’s financial assets and liabilities measured at fair value consisted of cash and cash equivalents, debt and foreign currency forward contracts. Cash and cash equivalents are comprised of bank deposits and short-term investments, such as money market funds, the fair value of which is based on quoted market prices, a Level 1 fair value measure. The Company employs Level 2 fair value measurements for the disclosure of the fair value of its various lines of credit and long term debt. The fair value of the Company's debt approximates the carrying value for all periods presented. The fair values of foreign currency forward contracts, used by the Company to manage the impact of foreign exchange rate changes, are based on quotations from financial institutions, a Level 2 fair value measure. See Note 17, Derivatives and Hedging, for a more complete description of the fair value measurements employed. Non-financial assets for which the Company employs fair value measures on a non-recurring basis include: • Long-lived assets • Investments • Assets acquired in a business combination • Impairment assessment of Goodwill and intangible assets • Long-lived assets held for sale Level 2 and level 3 inputs are employed by the Company in the fair value measurement of these assets. For the fair value measurements employed by the Company for certain property, plant and equipment, production assets, investments and prepublication assets, the Company assessed future expected cash flows attributable to these assets.

Income Tax And Non Income Tax Disclosure [Abstract]
Income Taxes and Other Taxes	INCOME TAXES AND OTHER TAXES Income Taxes In calculating the provision for income taxes on an interim basis, the Company uses an estimate of the annual effective tax rate based upon currently known facts and circumstances and applies that rate to its year-to-date earnings or losses. The Company’s effective tax rate is based on expected income and statutory tax rates and takes into consideration permanent differences between financial statement and tax return income applicable to the Company in the various jurisdictions in which the Company operates. The effect of discrete items, such as changes in estimates, changes in enacted tax laws or rates or tax status, and unusual or infrequently occurring events, is recognized in the interim period in which the discrete item occurs. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or as the result of new judicial interpretations or regulatory or tax law changes. The Company's interim effective tax rate, inclusive of discrete items, was 28.0% for the three month period ended February 29, 2020 and 27.4% for the nine month period ended February 29, 2020 . The Company, including its domestic subsidiaries, files a consolidated U.S. income tax return, and also files tax returns in various states and other local jurisdictions. Also, certain subsidiaries of the Company file income tax returns in foreign jurisdictions. The Company is routinely audited by various tax authorities. Non-income Taxes The Company is subject to tax examinations for sales-based taxes. A number of these examinations are ongoing and, in certain cases, have resulted in assessments from taxing authorities. The Company assesses sales tax contingencies for each jurisdiction in which it operates, considering all relevant facts including statutes, regulations, case law and experience. Where a sales tax liability with respect to a jurisdiction is probable and can be reliably estimated for such jurisdiction, the Company has made accruals for these matters which are reflected in the Company’s Condensed Consolidated Financial Statements. These amounts are included in the Financial Statements in Selling, general and administrative expenses. Future developments relating to the foregoing could result in adjustments being made to these accruals. On June 21, 2018, the U.S. Supreme Court issued its opinion in South Dakota v. Wayfair, Inc. et. al., reversing prior precedent, in particular Quill Corp. v. North Dakota (1992), which held that states could not constitutionally require retailers to collect and remit sales or use taxes in respect to mail order or internet sales made to residents of a state in the absence of the retailer having a physical presence in the taxing state. As a result, the Company now has an obligation, at least on a going forward basis, to collect and remit sales and use taxes, primarily in respect to sales made through its school book club channel, as well as certain sales made through its ecommerce internet sites, to residents in states that the Company has not previously remitted sales or use taxes based on its having no physical presence in such states. As of February 29, 2020 , the Company’s school book club channel was remitting sales taxes in 44

Derivatives and Hedging	DERIVATIVES AND HEDGING The Company enters into foreign currency derivative contracts to economically hedge the exposure to foreign currency fluctuations associated with the forecasted purchase of inventory, the foreign exchange risk associated with certain receivables denominated in foreign currencies and certain future commitments for foreign expenditures. These derivative contracts are economic hedges and are not designated as cash flow hedges. The Company marks-to-market these instruments and records the changes in the fair value of these items in Selling, general and administrative expenses and it recognizes the unrealized gain or loss in Other current assets or Other current liabilities. The notional values of the contracts as of February 29, 2020 and February 28, 2019 were $26.0 and $30.0 , respectively.

Accounting Policies [Abstract]
Principles of consolidation	Principles of consolidation The accompanying condensed consolidated interim financial statements (referred to as the “Financial Statements” herein) include the accounts of Scholastic Corporation (the “Corporation”) and all wholly-owned and majority-owned subsidiaries (collectively, “Scholastic” or the “Company”). Intercompany transactions are eliminated in consolidation.
Interim Financial Statements	Interim Financial Statements The accompanying Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information, and should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended May 31, 2019 . The Financial Statements presented in this Quarterly Report on Form 10-Q are unaudited; however, in the opinion of management, the Financial Statements reflect all adjustments, consisting solely of normal, recurring adjustments, necessary for the fair presentation of the Financial Statements for the periods presented.
Seasonality	Seasonality The Company’s Children’s Book Publishing and Distribution school-based book club and book fair channels and most of its Education businesses operate on a school-year basis; therefore, the Company’s business is highly seasonal. As a result, the Company’s revenues in the first and third quarters of the fiscal year generally are lower than its revenues in the other two fiscal quarters. Typically, school-based channels and magazine revenues are minimal in the first quarter of the fiscal year as schools are not in session. Trade sales can vary throughout the year due to varying release dates of published titles. The Company generally experiences a loss from operations in the first and third quarters of each fiscal year.
Use of estimates	Use of estimates The preparation of these Financial Statements involves the use of estimates and assumptions by management, which affects the amounts reported in the Financial Statements and accompanying notes. The Company bases its estimates on historical experience, current business factors, and various other assumptions believed to be reasonable under the circumstances, all of which are necessary, in order to form a basis for determining the carrying values of certain assets and liabilities. Actual results may differ from those estimates and assumptions. On an on-going basis, the Company evaluates the adequacy of its reserves and the estimates used in these calculations, including, but not limited to: • Accounts receivable allowance for doubtful accounts • Pension and postretirement benefit plans • Uncertain tax positions • The timing and amount of future income taxes and related deductions • Inventory reserves • Cost of goods sold from book fair operations during interim periods based on estimated gross profit rates • Sales tax contingencies • Royalty advance reserves and royalty expense accruals • Impairment testing for goodwill, intangible and other long-lived assets and investments • Assets and liabilities acquired in business combinations • Variable consideration related to anticipated returns • Allocation of transaction price to performance obligations
New Accounting Pronouncements	New Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The updates in this guidance remove the following exceptions: 1. Exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); 2. Exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; 3. Exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; 4. Exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also simplifies the accounting for income taxes by: 1. Requiring an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax; 2. Requiring an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction; 3. Specifying an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements; 4. Requiring an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The guidance further provides a policy election to not allocate consolidated income taxes when a member of a consolidated tax return is not subject to income tax and provides guidance to evaluate whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. The ASU will be effective for the Company in the first quarter of fiscal 2022. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. An entity that elects to early adopt in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period and an entity that elects early adoption must adopt all the amendments in the same period. The Company is evaluating the impact of this ASU on its consolidated Financial Statements. Current Fiscal Year Adoptions Topic 842, Leases Refer to Note 11, Leases , for a discussion of the Company's lease accounting following the adoption of ASU No. 2016-02, Leases (Topic 842) in the first quarter of fiscal 2020. ASU No. 2018-15 In August 2018, the FASB issued ASU No. 2018-15, Intangibles- Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The Company adopted ASU No. 2018-15 as of the beginning of the first quarter of fiscal 2020 using the prospective approach. In the third fiscal quarter, the Company capitalized approximately $9.5 of cloud computing costs which have not yet been placed into service. This amount is included within Other assets and deferred charges within the Company's Condensed Consolidated Balance Sheets and within the operating activities section of the Company's Condensed Consolidated Statement of Cash Flows. ASU No. 2018-02 In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220)-Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The Company adopted ASU No. 2018-02 as of the beginning of the first quarter of fiscal 2020 which resulted in no impact to the Company's financial statements.
