In January 2015, the Virginia Department of Education (VDOE) in the Commonwealth of Virginia was awarded a 4-year federal Preschool Development Grant (PDG) to expand high-quality preschool programs for at-risk 4-year-olds in 111 of Virginia’s 132 school divisions that ranked highest in need on key indicators. Virginia was one of 18 states that received PDG funds to increase access to high-quality preschool. Since the PDG grant augmented Virginia’s existing state-funded Virginia Preschool Initiative (VPI), Virginia named the work being carried out through its PDG grant the Virginia Preschool Initiative Plus (VPI+). This evaluation report examines VPI+ program implementation and impacts across the 4 years of the initiative (beginning in the 2015–2016 school year and ending in the 2018–2019 school year).
