The purpose of this project is to assist the Administration for Children and Families (ACF), states, and localities in understanding what drives workforce turnover in the early care and education (ECE) field and to evaluate promising strategies to support recruitment and retention of a qualified ECE workforce. The dynamics contributing to high rates of staff departures in some center-based ECE programs and decreasing supply of family child care providers, including individuals paid to provide noncustodial care, are not well understood. It is critical that ACF learns more about what motivates individuals to enter jobs in child care and early education and about what supports their attachment to the field. Better comprehension of how various conditions, incentives and strategies may differentially affect ECE workers, depending on individuals’ backgrounds, programmatic and local contexts, and features of care settings can inform public and private efforts, and especially the initiatives of the Office of Child Care and Office of Head Start to support states and programs in their activities to build and retain a qualified ECE workforce.(author abstract)
