On August 9, 2023, ASPE, in collaboration with NORC at the University of Chicago, held a virtual convening to 1) discuss how states and localities are effectively using data and data systems to address early childhood (EC) workforce issues and 2) how federal agencies can support states, localities, and tribes with technical assistance (TA), resources, and other support. Forty-nine administrators, researchers, and experts from local, state, and federal agencies that focus on EC workforce issues attended the convening. Representatives from five states (Florida, Iowa, Nebraska, Oregon, Virginia) participated as session panelists. In two panels, states shared strategies for management and use of workforce data. Panels focused on building data infrastructure (Virginia, Florida, and Iowa) and partnerships (Oregon and Nebraska). In facilitated large and small group discussions, participants identified factors that contributed to efforts in operating at scale; challenges that states faced in their efforts and solutions; and what TA, resources, or research states, localities, and tribes need to use workforce data for impact.
