Comprehensive, integrated data is a critical and valued tool for informed decision-making, policy prioritization, and resource targeting. However, in North Carolina (NC) and many other states, existing data and new data collection can often be fragmented, uncoordinated, and inaccessible. Through philanthropic investment from the Duke Endowment and public investments from North Carolina’s Division of Child Development and Early Education (DCDEE), the statewide Early Childhood Data Advisory Council (ECDAC) was established. The convening of this unique circle of thought leaders helped improve data systems and access through efficient responses to system advancement questions and policy recommendation proposals under consideration. There has been strong appreciation for the role of the ECDAC by state agencies and nonprofit organizations focused on improving outcomes for children and families. (author abstract)
