To measure impact and support program improvement, the Virginia Department of Education (VDOE) contracted with SRI International (SRI) in late August 2015 to conduct a comprehensive evaluation of VPI+, including a formative evaluation of VPI+ implementation, a summative evaluation of VPI+ impact on children's school readiness and later academic outcomes, and a cost analysis to determine investments needed for desired outcomes. The PDG funds support two types of preschool classrooms in high-need communities within 11 school divisions across the state: (1) VPI+ classrooms (i.e., newly-opened classrooms that implement all of the VPI+ grant requirements) and (2) VPI Improved classrooms (i.e., existing state-funded classrooms that enhance their quality by implementing at least one of five program quality enhancements). Due to budgetary constraints, VDOE decided to focus the external evaluation on only VPI+ classroom implementation and child outcomes (not VPI Improved classrooms), given VPI+ classrooms will be receiving the full treatment of initiative supports. Therefore, this Year 1 report presents findings on only VPI+ classrooms and children. (author abstract)
