Based on recent research and in collaboration with expert panelists, the What Works Clearinghouse™ (WWC) has provided practical recommendations for preschool educators to use to help prepare young children benefit from learning opportunities they will encounter in school. The "Preparing Young Children for School Practice Guide" details seven evidence-based practices designed to be used by teachers; center and program directors; district or state personnel involved in adopting curricula for preschool programs; and parents and caregivers. This introduction briefly describes the recommendations and how they are presented in the "Practice Guide." [For the Practice Guide, see ED621926.]
