A project for the analysis of State data from Wisconsin's Child Care Data Warehouse, and data from the Statewide Child Care Resource & Referral Data Base, to understand the population of families who receive child care subsidies, as well as the supply of care from which they choose. The project examines child care quality in relationship to State child care policies, focusing on shifts in usage of subsidies, changes in the child care marketplace, and assessments of child care quality over time. It includes an examination of the quality of subsidized and non-subsidized child care to identify indicators of quality and beneficial policies, through observations of child care facilities and interviews with 200 programs to assess structural features and processes in subsidized and non-subsidized care.
