Families, teachers and policy makers increasingly understand that high-quality pre-kindergarten is a critical part of children's educational experience. In 13 states and the District of Columbia, Pre-K programs are financed through the school funding formula. This report, co-written with the Education Law Center, discussed the benefits and challenges integrating early education into states' general education funding structures and explored the different models for employing such a strategy. Individual sections contain footnotes. (Contains 2 tables and 44 endnotes.)
