These financial statements are the responsibility of the Plan's Administrative Committee. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2002 and 2001, and the changes in its net assets available for benefits for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2002 is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's Administrative Committee. This supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ Ernst & Young LLP New York, New York April 16, 2003 1 <Page> SCHOLASTIC CORPORATION 401(k) SAVINGS AND RETIREMENT PLAN STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS AS OF DECEMBER 31, 2002 AND 2001 (AMOUNTS IN THOUSANDS) <Table> <Caption> DECEMBER 31, 2002 2001 ---- ---- INVESTMENTS, AT FAIR VALUE Putnam Stable Value Fund $ 20,989 $ 17,601 The George Putnam Fund of Boston 20,524 22,068 Putnam Investors Fund 14,905 19,422 Scholastic Corporation Common Stock 12,770 16,214 Putnam S & P 500 Index Fund 11,853 13,562 The Putnam Fund for Growth & Income 10,087 11,717 Putnam Bond Index Fund 7,360 4,130 Putnam New Opportunities Fund 5,669 7,191 Putnam International Growth Fund 4,243 4,269 Participants loans 3,772 3,389 Putnam Asset Allocation Fund - Balanced Portfolio 3,514 3,307 Putnam Asset Allocation Fund - Growth Portfolio 3,327 3,072 Putnam OTC & Emerging Growth Fund 2,583 3,115 Putnam Asset Allocation Fund - Conservative Portfolio 2,015 1,679 Putnam Capital Opportunities Fund 786 - Cash 15 - ------------ ------------ TOTAL INVESTMENTS 124,412 130,736 ------------ ------------ RECEIVABLES Participants contribution receivable 121 106 Employer contribution receivable 46 39 ------------ ------------ TOTAL RECEIVABLES 167 145 ------------ ------------ NET ASSETS AVAILABLE FOR BENEFITS $ 124,579 $ 130,881 ============ ============ </Table> SEE ACCOMPANYING NOTES 2 <Page> SCHOLASTIC CORPORATION 401(k) SAVINGS AND RETIREMENT PLAN STATEMENT OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS YEAR ENDED DECEMBER 31, 2002 (AMOUNTS IN THOUSANDS) <Table> Interest and dividend income $ 2,493 Contributions Employer 5,518 Participants 14,670 Rollovers 2,394 ------------ TOTAL ADDITIONS 22,582 Distributions to participants (8,185) Net realized and unrealized depreciation in fair value of investments (23,192) ------------ NET DECREASE (6,302) NET ASSETS AVAILABLE FOR BENEFITS Beginning of period 130,881 ------------ End of period $ 124,579 ============ </Table> SEE ACCOMPANYING NOTES 3 <Page> SCHOLASTIC CORPORATION 401(k) SAVINGS AND RETIREMENT PLAN NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF THE PLAN GENERAL The Scholastic Corporation 401(k) Savings and Retirement Plan, amended and restated effective January 1, 1998 and subsequently amended effective January 1, 2002 (the "Plan"), formerly the Scholastic Inc. 401(k) Savings and Retirement Plan, is a defined contribution plan sponsored by Scholastic Corporation (the "Company"). The Plan is administered by the Retirement Plan Committee of the Board of Directors of the Company, which has delegated certain responsibility and authority to the Company's Administrative Committee, which is composed of members of senior management of the Company (the "Retirement Plan Committee," and to the extent delegated to the Administrative Committee, collectively the "Committee"). Putnam Fiduciary Trust Company serves as Trustee for the Plan (the "Trustee"). In addition, Putnam Fiduciary Trust Company and/or its related companies (collectively, "Putnam") also provide administrative and recordkeeping services on behalf of the Plan (the "Record Keeper"). Investment products offered, through December 31, 2002, to participants under the Plan ("Participants"), other than the Company's common stock ("Company Stock"), were provided by Putnam. The Plan is an employee plan qualified under Section 401(a) of the Internal Revenue Code, as amended (the "Code"). This description of the Plan provides only general information and is presented to assist in understanding the Plan's financial statements. Participants should refer to the Plan Document for a more complete description of the Plan's provisions. PLAN AMENDMENTS As mentioned above, the plan document was amended and restated effective January 1, 1998. This amended and restated document was updated during 2001 to reflect all amendments effective through 2001. The plan document was subsequently amended effective January 1, 2002. The amendment effective January 1, 2002 (and April 1, 2002 for the catch-up contribution feature referred to below) revised the Plan to comply with and incorporate the Economic Growth and Tax Relief Reconciliation Act of 2001 ("EGTRRA"), as well as to make certain plan design changes related to EGTRRA. The changes included: (i) increasing the annual Compensation (as defined below) recognized by the Plan from $170,000 to $200,000, (ii) increasing the Plan's pre-tax and after-tax deferral limits (on an individual and combined basis) from 20% to 50% of annual Compensation for non-Highly Compensated Employees (as defined below), (iii) establishing the Plan's pre-tax and after-tax deferral limits (on an individual and combined basis) to 6% of annual Compensation for Highly Compensated Employees, (iv) permitting Participants who are age 50 and older or who will attain age 50 before the end of the Plan Year (which is the twelve month period beginning January 1 and ending on December 31) to make catch-up contributions (as defined by EGTRRA), (v) increasing the annual pre-tax deferral limit to $11,000 in 2002, with subsequent increases up to $15,000 in 2006, (vi) allowing the Plan to accept direct rollovers of eligible distributions from annuity contracts described in Section 403(b) of the Code, governmental plans under Section 457(b) of the Code, and individual retirement 4 <Page> accounts or annuities, as well as after-tax distributions from other employer plans qualified under Section 401(a) of the Code , and (vii) shortening the suspension period for participating in the Plan after hardship withdrawals from twelve months to six months. Also effective January 1, 2002, the Plan was amended to permit automatic enrollment of new Eligible Employees (as defined below) hired on or after January 1, 2002. Eligible Employees are automatically enrolled as soon as administratively feasible after 90 days of employment. Contributions are made at a pre-tax contribution rate of 3% of annual Compensation and are deposited in the Putnam Asset Allocation: Balanced Portfolio. ELIGIBILITY Employees eligible to enroll in the Plan include all employees of the Company and its domestic subsidiaries (other than "leased" employees) who have attained the age of 18 ("Eligible Employees"). Eligible Employees may enroll in the Plan on any business day after they become eligible to participate in the Plan. Employees hired on or after January 1, 2002 are automatically enrolled as soon as administratively feasible after 90 days of employment. PARTICIPANT CONTRIBUTIONS As approved by the Committee and subject to the provisions of the Code, Eligible Employees may contribute during the Plan Year at the Participant's election into any of the Plan's fund options, in pre-tax and/or after-tax Compensation dollars ("Compensation Contributions"); provided, that the sum of pre-tax and after-tax contributions during any Plan Year does not exceed the following limitations: PRE-TAX CONTRIBUTIONS: Pre-tax contributions are limited to the lesser of 50% of annual salary, overtime, bonuses and commissions ("Compensation"), subject to the requirements of the Code, or $11,000 for the Plan Year ended December 31, 2002. Eligible Employees whose Compensation is in excess of $85,000 in the prior year ("Highly Compensated Employees") are limited to the lesser of 6% of their annual Compensation or $11,000 for the Plan year ended December 31, 2002. The sum of pre-tax and after-tax contributions during any Plan Year cannot exceed 50% (or 6%, if a Highly Compensated Employee) of annual Compensation. AFTER-TAX CONTRIBUTIONS: After-tax contributions are limited to 50% of annual Compensation, subject to the requirements of the Code. Highly Compensated Employees are limited to a contribution of 6% of their annual Compensation. The sum of pre-tax and after-tax contributions during any Plan Year cannot exceed 50% (or 6% if a Highly Compensated Employee) of annual Compensation. ROLLOVER CONTRIBUTIONS: Any Eligible Employee may transfer to the Plan contributions and such other amounts from an "eligible rollover plan" that meets the requirements of the Code at the time of the transfer ("Rollover Contributions"). EMPLOYER CONTRIBUTIONS Under the Plan, the Company contributes a percentage of each Participant's Compensation, as determined by the Committee, at its sole discretion. The Company's contributions for the benefit of the Participants are made in cash in an amount equal to a percentage of the Participant's pre-tax contributions. For the Plan year ended December 31, 2002, the Company contributed an amount equal to 100% of the first one hundred dollars of a Participant's contribution and 50% 5 <Page> thereafter of the Participant's pre-tax contributions, up to a maximum amount equal to 6% of the Participant's annual Compensation ("Matching Contributions"). The Company, at its sole discretion, may also make discretionary contributions for the benefit of all Participants regardless of whether they elected to make pre-tax contributions to the Plan ("Discretionary Contributions"). The amount of such Discretionary Contributions is to be determined by the Board of Directors of the Company (the "Board"). The Company made no Discretionary Contributions to the Plan for the year ended December 31, 2002. Forfeitures by Participants of unvested Matching Contributions ("Forfeitures") are used to offset Matching Contributions for other Participants. In 2002, Matching Contributions were reduced by $169,764 from Forfeitures. At December 31, 2002, Forfeitures totaled $104,152, which will be used to reduce future Matching Contributions. VESTING Participants are immediately vested in their Compensation Contributions and Rollover Contributions. Matching Contributions vest at the rate of 20% per year of service by a Participant. A Participant becomes 100% vested in all Matching Contributions after either five years of credited service, or upon death or disability while employed, or upon reaching age 65. PARTICIPANT ACCOUNT DISTRIBUTIONS A Participant's account under the Plan may be distributed in full upon cessation of employment for any reason, including termination, death, disability or retirement. On a daily basis, a Participant, for any reason, may withdraw all or a portion of his or her after-tax contributions. All distributions from the Plan are in cash or, if elected by the Participant, in whole shares of Company Stock, to the extent that the Participant is invested in the Company Stock. In the event of attainment of age 59-1/2, a Participant may withdraw his or her entire vested balance during employment. Benefits payable (but not yet paid) as of December 31, 2002 and 2001 were $0 and $3,787, respectively. In the event of a hardship, a Participant may withdraw during employment such portion of his or her account to meet such hardship. In addition, once each Plan Year, Participants may request a loan from the Plan of up to 50% of the vested value of their account not to exceed $50,000. In no event may a Participant have more than one loan for the purchase of a principal residence outstanding or more than two outstanding loans at any time. All loans must be repaid in equal installments of principal and interest through automatic payroll deductions over a period not to exceed five years, except for certain loans made to purchase a Participant's principal residence, which may be repaid over a period of up to ten years pursuant to the Code. Participants may not otherwise withdraw any portion of their account balance during employment. PLAN EXPENSES Expenses are incurred at either the fund level or the Plan level. All expenses incurred by the funds (commissions, management fees, etc.) are paid out of investor assets and are therefore netted in realized and unrealized depreciation in fair value of investments in the statement of changes in net assets available for benefits. The Company pays all other Plan expenses. 6 <Page> 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The financial statements of the Plan are prepared in accordance with accounting principles generally accepted in the United States. The Plan's accounts are maintained on the accrual basis. Purchases and sales of investment securities are recorded at market value on the trade date. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. VALUATION OF INVESTMENTS Investments in the Plan's funds are valued at redemption prices based on the net asset values of the funds. Investments in Company Stock are valued at the closing price as quoted on the NASDAQ National Market System on the valuation date. Loans receivable from Participants are valued at cost which approximates fair value. 3. TAX STATUS The Plan received a favorable determination letter from the Internal Revenue Service as of November 1, 1995 that the Plan qualifies under Section 401(a) of the Code. Therefore, the Plan's assets are not subject to tax under Section 501(a) of the Code. The Plan is required to operate in conformity with the Code in order to maintain its qualification. If any operational defects are identified, the Company will take all action necessary to correct and maintain the qualified status of the Plan. As a result of amending and restating the Plan, the Company filed for a new determination letter on June 28, 2002. 4. PLAN TERMINATION While the Plan is intended to be permanent, it may be terminated at any time by a resolution of the Board, subject, however, to the provisions of ERISA. Upon termination of the Plan, all necessary provisions of the Plan shall remain in effect, no further contributions may be made to the Plan and the account of each Participant shall become fully vested and non-forfeitable. In the event of termination, the Plan assets may continue to be held by the Trustee. However, upon a determination that the continuance of such an arrangement is not in the best interest of the Participants, the Board may terminate the arrangement, and upon such termination, the Trustee shall apply for the benefit of each Participant (or beneficiary) the full value of such Participant's account. 7 <Page> 5.
