The federal child care subsidy system supports low-income working families with child care financial assistance through the Child Care and Development Fund, which is administered by the Office of Child Care (OCC), Administration for Children and Families, U.S. Department of Health and Human Services. The most recently available data from OCC show the federal child care subsidy system in the United States served 1.4 million children in 847,400 families in fiscal year 2015. While an extensive body of research has examined numerous aspects of the system, a less-studied component is the experiences of the participating providers, who numbered 339,000 in fiscal year 2015. This Research-to-Policy Resource List compiles publications in the Research Connections collection on providers' experiences of the child care subsidy system, particularly their decisions to participate in and their experiences of it. Only research that collected data directly from providers about their experiences is included. Following an overview document and research conducted in multiple states, the remaining resources are grouped by individual state.
