The Building Capacity to Use Linked Data project has developed several short, easy-to-read resources to help program leaders work toward linking their data with data from other agencies, and using linked data to support quality improvement. One of these resources includes a research brief titled, Strength in Numbers: Supporting Quality Improvement in Early Care and Education Programs through Linking Administrative Data. This brief may be useful for both ECE program leaders and community or state partners who are interested in linking data with ECE programs. The brief highlights opportunities and challenges in linking data and offers ideas for overcoming identified challenges.
