The PDG B-5 grant allows Illinois to develop and update an overarching statewide strategic plan, informed by a statewide needs assessment, which will guide systemic efforts to coordinate Illinois' mixed delivery system so all children and families have access to the services and supports they need to thrive. Illinois is also conducting activities to: maximize parent and family choice, knowledge, and engagement in Illinois' early childhood education and care (ECEC) system; share best practices and enhance professional development to support the ECEC workforce; improve quality and service integration and expand access to ECEC programs and services across the State; and monitor, evaluate, and improve data collection and use for continuous improvement.
