(1) There is hereby created in the state treasury the public school health insurance participation fund. The fund is continuously appropriated to the state department of education for the purpose of funding the actuarially established onetime amount required for a public school to buy in to the state’s medical and dental group insurance plan. The fund shall consist of moneys made available through legislative transfers, appropriations, or as otherwise provided by law and shall be available for use only to publicly funded K-12 educational institutions. Interest earnings from the investment of moneys in the fund shall be returned to the fund.
(2)  All moneys in the fund shall be used only for onetime expenses associated with accommodating participation into the state’s health plan as set forth in this section. The state department of education shall make payment or payments to the office of group insurance for this purpose within a reasonable time of participants being identified. If demand exceeds available funds, the state department of education shall administer the fund on a first-come, first-served basis. No funds may be expended prior to July 1, 2022, and any unexpended moneys remaining in the fund after June 30, 2025, shall be transferred by the state controller to the public education stabilization fund. If the public education stabilization fund is fully funded, then remaining funds shall be transferred to the general fund.
