This report looks at the relationship between participation in Washington’s state funded preschool, the Early Childhood Education and Assistance Program (ECEAP), and performance on the Washington Kindergarten Inventory of Developing Skills (WaKIDS) with a focus on Hispanic children. This study was conducted because Hispanic children in general and Hispanic dual-langauge learners (DLLs) represent a sizeable proportion of the lower-income student population in Washington.
