The Center for the Study of Child Care Employment (CSCCE) receives support from the Birth to Five Policy Alliance and the David and Lucile Packard Foundation to assist states with early care and education (ECE) workforce systems development. Their efforts include membership in the Early Childhood Data Collaborative (ECDC), and their participation in a Workforce Systems Alignment Workgroup (Workgroup) with leaders of the three main ECE workforce systems described in this brief. This brief is an outgrowth of the Workgroup's efforts to align existing workforce systems operating in the states in order to expand their capacity to serve as the workforce component of broader state coordinated ECE data systems. It describes the early care and education workforce data landscape in the states, focusing on the three main workforce data systems operating across multiple states. The brief also details the challenges to aligning these systems and current efforts to address these challenges. (Contains 1 table, 4 boxes and 7 footnotes.)
