Allowances received by districts pursuant to subdivisions (a) and (b) of Section 60242 shall be deposited into a separate account as specified by the Superintendent of Public Instruction. These allowances, including any interest generated by them, shall be used only for the purchase of instructional materials, tests, classroom library materials, or in-service training pursuant to subdivisions (a) and (b) of Section 60242. Interest posted to the account shall be based upon reasonable estimates of monthly balances in the account and the average rate of interest earned by other funds of the district.
All purchases of instructional materials made with funds from this account shall conform to law and the applicable rules and regulations adopted by the state board, and the district superintendent shall provide written assurance of conformance to the Superintendent of Public Instruction. The Superintendent of Public Instruction may withhold the allowance established pursuant to Section 60242 for any district which has failed to file a written assurance for the prior fiscal year. The Superintendent of Public Instruction may restore the amount withheld once the district provides the written assurance.
The Controller, in cooperation with the State Department of Education, shall include procedures to review compliance with this section in its independent audit instructions.
