This brief describes Florida's Voluntary Prekindergarten Program (VPK), which serves a higher percentage of four-year-olds than any other state preschool program in the country. In 2005, Florida introduced VPK, a free, universal preschool initiative. Florida's implementation of the VPK program represents the most rapid expansion of state-funded preschool in the United States. VPK currently serves about 80 percent of the state's four-year-olds and is forecasted to reach almost 90 percent in 2015-16 (Office of Economic & Demographic Research, 2013). These participation rates make Florida's program a clear exemplar with respect to access. However, VPK is also criticized for relatively low levels of per-student funding and lax quality regulations, which stand in contrast to more highly-regulated and expensive state preschool programs, particularly the universal programs in Oklahoma and Georgia. The brief presents Florida as a case study for states trying to leverage their existing early childhood infrastructure towards universal access. We outline how Florida's program defines eligibility, the role of the public school system, program oversight, funding, and quality regulations and discuss the implications for the program's impact.
