A project to establish a state-of-the-art early care and education data warehouse and build a Research Analysis and Evaluation Unit within the Office of Child Care Services (OCCS). The warehouse integrates data sets from many sources, including state administrative databases, census data, and state initiated research efforts. Along with the development of in-house expertise in research and analysis, the warehouse supports the evaluation of state quality program initiatives, such as tiered rate increases, and assessments of the longitudinal impact of program quality on school readiness.
