In April 2019, Substitute Senate Bill 5437 directed the Washington State Department of Children, Youth, and Families (DCYF) to begin the "phased implementation of a birth to three early childhood education and assistance program pilot project for eligible children under thirty-six months old." This model is called Early ECEAP and is based on the highly successful child and family outcomes of both Early Head Start (EHS) and Washington's state-funded preschool, the Early Childhood Education and Assistance Program (ECEAP). ECEAP is designed to prepare 3- and 4-year-old children furthest from opportunity for success in school and in life. This report presents background and details of the Early ECEAP Pilot Project.
