The University of Arkansas at Little Rock will use data from the Early Head Start (EHS) National Evaluation Study to examine a variety of personal, familial, and contextual factors that may moderate program impacts on children. Specifically, the study will examine who benefits from early education, what factors help determine who benefits, and what mechanisms account for the impacts observed. Focus will also be on moderators of program impacts because they provide insights into the processes responsible for change. It is expected that results of the study will add to existing knowledge about the impacts of early education for infants and toddlers.
