At present, there is no requirement for local Head Start programs to link or share their data with other state data systems. However, several states are making advances toward linking and/or sharing data across their state’s K-12 data system or other services’ data systems. To better understand some of the challenges, successes, and strategies behind this work, the Early Childhood Data Collaborative (ECDC) contacted and interviewed a sample of Head Start and state early childhood leaders in a dozen states.
