This guide provides cross-sector teams at the state, territory, tribal, and local levels with strategies for collecting and using data across the mixed delivery system of early care and education programs. (This guide uses the term "state and local" to refer to all of these levels.) Collecting and analyzing qualitative and quantitative data can help inform teams to develop policy and practices that will eliminate exclusionary practices, provide the workforce with needed resources and support, and promote improved outcomes for young children and their families.
