Requires school districts receiving preschool education aid to establish mixed delivery system for preschool education.

This bill requires New Jersey school districts receiving preschool education funding to offer a "mixed delivery system," meaning they must provide preschool access through a combination of district-run programs, licensed child care centers, or Head Start. It directly affects school districts serving 3- and 4-year-olds, mandating free full-day preschool for all eligible children in districts with higher concentrations of at-risk students (group A/B and CD districts with ≥40% at-risk pupils), and for at-risk pupils only in other districts. The key mechanism establishes a specific funding formula calculating aid based on how many children are served through each delivery option (district, child care, or Head Start), with districts required to submit a 5-year plan to implement full-day preschool by 2013-14. The policy change focuses on structuring how preschool funding is distributed and delivered, not on creating new programs or outcomes.
