This summative assessment report provides the Virginia Department of Education and the 11 school divisions participating in VPI+ with information on children's development in fall 2015. The data can be used to better understand what skills and abilities the children had when they enrolled in the VPI+ preschool program in the fall and also can be used to inform instruction and programming in the second half of the school year. Another summative assessment report will be issued in the spring. Those data can be used to assess how well the state and divisions are reaching their goals of increasing the kindergarten readiness of children in VPI+ and to identify areas of instruction that could be improved the following year to support children's development and learning.
