Through our analysis of states’ applications for Preschool Development Grant funding, we examine and uplift the ways in which state leaders are using the latest round of Preschool Development Grant funding to address data integration needs and advance the use of early childhood data to guide early childhood policies and practices. Of particular interest are states’ efforts to develop early childhood integrated data systems (ECIDS), as well as coordinated service eligibility and applications systems. An ECIDS coordinates information about program participation, child care supply, and workforce characteristics from multiple data systems. When combined, these data can be used to help policymakers, practitioners, and researchers understand which families have access to programs, where there are service and workforce gaps, how children fare later in their educational trajectories, and what programs best meet the needs of children and families. Note that this analysis is not a comprehensive scan of the national scope of early childhood data integration, but rather a scan of those efforts funded through the 2022 round of PDG B-5 grants. The brief first provides an overview of these grants, the data integration activities they fund, and the methodology used for this analysis. The next section summarizes states’ reported use of PDG funds to plan, implement, or expand early childhood data integration. (author abstract)
