In 2014, New Jersey was one of 18 states awarded a federal grant aimed to enhance state preschool programs, improve quality and serve more eligible children in high-quality settings. This "Preschool Development Grant" (PDG) promised to provide the state with $17.5 million per year for four years, beginning on January 1, 2015 through December 31, 2018. Children from low-income families in 16 identified communities were eligible and would have access to the same high-quality standards as existing districts with state-funded universal preschool. This policy brief describes the findings and outcomes of implementing the Preschool Development Grant, the benefits this funding provides in helping at-risk children enter kindergarten better prepared and the possible consequences when the federal funding ends. The report includes data from the New Jersey Department of Education, survey responses from all 16 participating districts as well as individual and group interviews with key district staff members collected between March and May 2017.
