             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Participants and Administrator of the
PLATO Learning, Inc. Savings and Retirement Plan


In our opinion, the accompanying statements of assets available for benefits and
the related statement of changes in assets available for benefits present
fairly, in all material respects, the assets available for benefits of PLATO
Learning, Inc. Savings and Retirement Plan (the "Plan") at December 31, 2004 and
2003, and the changes in assets available for benefits for the year ended
December 31, 2004, in conformity with accounting principles generally accepted
in the United States of America. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with the standards of the Public
Company Accounting Oversight Board (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, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental Schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required part of the basic 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 management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

As further described in Note 1, the Lightspan, Inc. 401(k) Profit Sharing Plan
("Lightspan Plan") was merged into the Plan during 2004, with $9.0 million of
Lightspan Plan assets transferred into the Plan.

PLATO LEARNING, INC. SAVINGS AND RETIREMENT PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004 AND 2003
- --------------------------------------------------------------------------------

1.    DESCRIPTION OF PLAN

      The following description of the PLATO Learning, Inc. (the "Company")
      Savings and Retirement Plan (the "Plan") is provided for general
      informational purposes only. Participants should refer to the Plan
      document for a more complete description of the Plan's provisions.

      Effective March 1, 2004, the Lightspan, Inc. 401(k) Profit Sharing Plan
      ("Lightspan Plan") was merged into the Plan, and Lightspan Plan assets
      available for benefits of $8,997,614 were transferred to the Plan pursuant
      to the terms of the Plan.

      GENERAL
      The Plan is a contributory defined contribution plan covering all eligible
      employees of the Company. The Plan is subject to the provisions of the
      Employee Retirement Income Security Act of 1974, as amended ("ERISA").

      ELIGIBILITY REQUIREMENTS
      All employees of the Company are eligible to participate in the Plan upon
      the completion of three months of employment provided they are least 21
      years of age.

      CONTRIBUTIONS
      Participant contributions are recorded in the period the employer makes
      the payroll deductions. Employer matching contributions are accrued based
      on participant contributions. Participants may contribute up to 60% of
      their pre-tax compensation, up to a maximum dollar amount, as defined,
      subject to certain other Internal Revenue Service ("IRS") limitations.

      The Company may also make contributions to the Plan at its discretion. Any
      such amount must be designated by Company resolution. In 2004, the
      discretionary contribution was 50% for each dollar of participant
      contributions up to a maximum Company contribution of 2% of participant
      compensation, with a cap of $4,000 in total Company contributions per
      participant.

      PARTICIPANT ACCOUNTS
      Individual participant accounts are maintained by the Plan's recordkeeper,
      Administrative Management Group, Inc. Each participant's account is
      credited with the participant's contribution, Plan investment earnings or
      loss, net of administrative expenses, and an allocation of employer
      matching and discretionary contributions. Allocations are based on
      participant earnings and account balances, as defined. The allocation of
      the participant's contributions to these investment funds may be changed
      daily.

      VESTING AND FORFEITURES
      Participants are immediately vested in their contributions and actual
      earnings thereon.

      Participants vest in their Company contribution account based on the
      following schedule:



                                                          VESTED
             YEARS OF SERVICE                           PERCENTAGE
                                                     
             Less than 1 year                                0
             1 year but less than 2                        33-1/3
             2 years but less than 3                       66-2/3
             3 years or more                                100

PLATO LEARNING, INC. SAVINGS AND RETIREMENT PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004 AND 2003
- --------------------------------------------------------------------------------

      A participant will also become fully vested upon permanent disability or
      attainment of normal or early retirement as defined in the Plan.

      Forfeitures are used to reduce future contributions made by the Company.
      There were approximately $61,000 and $31,000 in forfeitures at December
      31, 2004 and 2003, respectively.

      BENEFIT PAYMENTS
      On termination of service due to death, disability or retirement, a
      participant may elect to receive either a lump-sum amount equal to the
      value of the participant's vested interest in his or her account, or
      installments over a specified time. For termination of service for other
      reasons, a participant may receive the value of the vested interest in his
      or her account as a lump-sum distribution.

      LOANS
      Participants may borrow from their fund accounts a minimum of $1,000 and
      up to a maximum equal to the lesser of $50,000 or 50% of their vested
      account balance. Loan terms are generally five years. The loans are
      collateralized by the balance in the participant's account and bear
      interest at a rate commensurate with local prevailing rates as determined
      by the plan administrator at the date of loan origination. Principal and
      interest is paid ratably through biweekly payroll deductions. Participant
      notes receivable have interest rates ranging from 5.0% to 9.5% and are due
      at various dates through December 2019. Repayments are invested among the
      various investment funds in the same manner as participant contributions.

      INVESTMENT OPTIONS
      The Plan offers nine investment options: seven mutual funds, one common
      collective trust fund and one Company stock fund. Pursuant to the plan
      agreement, a maximum of 30% of a participant's account balance can be
      allocated to Company stock. Plan participants direct the investment of
      their accounts among these nine options. Company contributions are
      invested in the fund options in the same manner as participant
      contributions.

      VOTING RIGHTS
      Each participant is entitled to exercise voting rights attributable to the
      Company shares allocated to his or her account and is notified by the
      Trustee prior to the time that such rights are to be exercised. The
      Trustee is not permitted to vote any allocated share for which a
      participant has not given instructions.

      PLAN TERMINATION
      Although it has not expressed any intent to do so, the Company has the
      right under the Plan to terminate the Plan subject to the provisions of
      ERISA. In the event of Plan termination, participants will become 100%
      vested in their accounts, and assets of the Plan will be distributed in
      accordance with the Plan document.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The following significant accounting policies were used to prepare the
      financial statements in accordance with accounting principles generally
      accepted in the United States of America.

      BASIS OF ACCOUNTING
      The accompanying financial statements have been prepared using the accrual
      basis of accounting.


                                       5

PLATO LEARNING, INC. SAVINGS AND RETIREMENT PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004 AND 2003
- --------------------------------------------------------------------------------

      VALUATION OF INVESTMENTS AND INCOME RECOGNITION
      The Plan's investments are stated at fair value, except for the stable
      value fund, which is a benefit-responsive investment contract valued at
      contract value. Quoted market prices are used to determine fair value of
      investments. Investments in mutual funds and common collective trust funds
      are valued at the net asset value as of year end. Participant loans are
      valued at estimated fair value, consisting of principal outstanding and
      any related accrued interest.

      The contract value of the benefit-response investment represents the
      principal balance of the investment contract, plus accrued interest at the
      stated contract rate, less withdrawals and administrative expenses. The
      fair value of the investment contract approximates contract value as of
      year end. The average yield and crediting interest rates were
      approximately 4% and 5% for 2004 and 2003, respectively.

      Purchases and sales of securities are recorded on a trade-date basis.
      Interest income is recorded on an accrual basis. Dividend income is
      recorded on the ex-dividend date.

      The Plan presents the net appreciation (depreciation) in the fair value of
      its investments in the Statement of Changes in Assets Available for
      Benefits, which consists of the realized gains or losses and the
      unrealized appreciation (depreciation) on those investments.

      ADMINISTRATIVE EXPENSES
      Administrative expenses, primarily transaction fees, are paid by the Plan.
      Other expenses for professional services and administration costs have
      been paid by the Company at its discretion.

      PAYMENT OF BENEFITS
      Benefits payments are recorded upon distribution.

      USE OF ESTIMATES
      The preparation of the financial statements in conformity with accounting
      principles generally accepted in the United States of America requires the
      Plan's administrator to make extensive use of estimates and assumptions
      that affect the reported amounts of assets available for benefits at the
      date of the financial statements and the changes in assets available from
      plan benefits during the reporting period and, when applicable,
      disclosures of contingent assets and liabilities. Actual results could
      differ from those estimates.

      RISKS AND UNCERTAINTIES
      The Plan provides for various investment options in various combinations
      of investment securities. Investment securities are exposed to various
      risk factors including, but not limited to, interest rates, market
      conditions and credit risks. Due to the level of risk associated with
      certain investment securities and the level of uncertainty related to
      changes in the value of investment securities, it is at least reasonably
      possible that changes in the values of investment securities will occur in
      the near term and that such changes could materially affect participants'
      account balances and the amounts reported in the Statements of Assets
      Available for Benefits in future periods.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004 AND 2003
- --------------------------------------------------------------------------------

      CONCENTRATION OF MARKET RISK
      As of December 31, 2004 and 2003, approximately 3% and 10% of the Plan's
      assets were invested in PLATO Learning, Inc. common stock, respectively.
      The underlying value of this fund is dependent on the performance of PLATO
      Learning, Inc. and the market's evaluation of such performance. It is at
      least reasonably possible that changes in the fair value of PLATO
      Learning, Inc. common stock in the near term could materially affect
      participants' account balances and the amounts reported in the Statements
      of Assets Available for Benefits and the Statement of Changes in Assets
      Available for Benefits.

PLATO LEARNING, INC. SAVINGS AND RETIREMENT PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004 AND 2003
- --------------------------------------------------------------------------------

4.    TAX STATUS

      The Plan is a prototype plan. The IRS has determined and informed the
      Trustee by letter dated May 9, 1996, that the prototype plan and related
      trust are designed in accordance with applicable sections of the IRC.
      Although the Plan has been amended since the date of this letter, the plan
      administrator believes that the Plan is currently designed and being
      operated in compliance with the applicable requirements of the IRC.
      Therefore, no provision for income taxes has been included in the Plan's
      financial statements.

5.    PLAN AMENDMENT

      Subsequent to December 31, 2002, the Company determined that participants
      were allowed to contribute certain compensation that did not meet the
      Plan's definition of Eligible Compensation. The Company is taking remedial
      actions under the Department of Labor Voluntary Compliance Program to
      correct the matter through retroactive amendment to the Plan's definition
      of Eligible Compensation whereby the definition was expanded to include
      all such compensation contributed by participants. The Company submitted
      its request to the IRS in June 2004, and as of the date of this report,
      the Company has not received a response. The plan administrator believes
      that the remedial actions being taken will be acceptable to the IRS;
      although, there can be no assurance as such until final approval is
      received.
