School aid: supplemental; funding for the great start readiness program; provide for. Amends 1976 PA 451 (MCL 380.1 - 380.1852) by adding sec. 1147a.

HB 4873 mandates annual state funding of $610 million for Michigan's Great Start Readiness Program (GSRP), beginning in fiscal year 2026. This program provides early childhood education and care for preschool-aged children, primarily affecting low-income families and communities with limited access to early learning services. The bill requires the legislature to appropriate this specific amount each year, guaranteeing stable funding for GSRP as defined under existing law (MCL 388.1632d). It does not create new eligibility rules but ensures consistent financial support for the existing program.
