The goal of this project is to develop an interagency, integrated data system for the purpose of assessing accessibility and quality of early care and education programs available to and utilized by low-income working parents and at-risk families, as well as the impact of quality initiatives to support the school readiness of children in the Commonwealth of Virginia. Steps to creating the unit include: identifying current data collected at the state and local levels; assessing data quality and gaps; establishing appropriate data sharing and protection agreements; and designing and incrementally building and deploying the system. The data system produced will be a web-accessible, data management system designed to provide reliable data usable by appropriate state, local, nonprofit, academic and other stakeholders, to increase support for policy-level decision-making in Virginia. The following questions are addressed: (1) What types of and what is the quality of child care being used by families in the subsidy program?; (2) Does this vary by locality and family characteristics, such as ethnicity?; and (3) How are these children faring in Kindergarten?
