Makes various changes to provision of preschool aid and facilities requirements; establishes Universal Preschool Implementation Steering Committee; requires full-day kindergarten in all school districts.

This bill establishes the "New Jersey Universal Preschool and Kindergarten Act" requiring all school districts to provide full-day kindergarten by the 2029-2030 school year. It creates a Universal Preschool Implementation Steering Committee to oversee preschool expansion and establishes preschool expansion grants for districts not currently providing State-funded preschool. The bill revises preschool education aid formulas to prioritize districts with higher concentrations of at-risk students and requires districts receiving preschool aid to partner with licensed childcare providers and Head Start programs. School districts must submit annual implementation plans and participate in quality improvement assessments. The legislation aims to expand access to high-quality preschool for all three- and four-year-olds in New Jersey.
