Executive Officer Compensation Summary

     Renaissance Learning, Inc.’s (the “Company’s”) executive officers consist
of Mr. John Hickey, President and Chief Executive Officer; Mr. Steven Schmidt,
Executive Vice President; Ms. Mary Minch, Chief Financial Officer; Mr. Terrance
Paul, Co-Chairman of the Board; and Ms. Judith Paul, Co-Chairman of the Board.

     The compensation structure for executive officers of the Company consists
of base salary, cash bonus, and stock option grants. The Company’s Incentive
Bonus Plan permits participants in the plan to receive up to 100% of their base
salary in a cash bonus which is tied to the performance of the Company. Bonus
awards are subject to a four year vesting period, vesting 25% per year beginning
one year from the date of the initial award. The vested portion of the award is
then paid out promptly upon vesting. Options granted under the Company’s Stock
Incentive Plan are granted at the fair market value of the stock on the date of
grant, are subject to a four year vesting schedule (vesting 25% per year
beginning one year from the date of grant), and expire 10 years from the date of
grant (subject to earlier termination in the event of termination of employment;
but see discussion of Mr. Hickey’s option grants below).

     Each executive receives a base salary, but only Mr. Schmidt and Ms. Minch
participate in the Company’s Incentive Bonus Plan. Only Mr. Hickey and
Mr. Schmidt participate in the Company’s Stock Incentive Plan. In addition, each
executive is entitled to receive 401(k) plan and supplemental executive
retirement plan (“SERP”) matching amounts contributed by the Company. The
Company does not have employment agreements with any of its executive officers.

     Compensation decisions affecting the Company’s executive officers are made

their full 10 year term.     •   Mr. Schmidt. The Committee approved a 5%
