Effective, coordinated state-level systems to support the most vulnerable children and youth have never been more important, as responsibilities increasingly devolve from the federal government to the states. This report is a snapshot of the national landscape of child and youth policy coordinating bodies. It is a source of inspiration to continue to innovate work to improve outcomes for children and youth. The work done by state child and youth policy coordinating bodies changes and shifts focus constantly as these bodies evolve and lead the charge toward better and more aligned systems and services. The changing results of the survey every two years reflects this progress and can be used by coordinating bodies as a source of ideas for new practices, examples from peers and a windsock for the direction in which coordinating bodies are headed.
