Child and youth coordinating bodies are systematically changing the fragmented ways that state and local governments do business for children and youth. Sometimes known as councils or commissions, children's cabinets are typically made up of the heads of all government agencies with child- and youth-serving programs. They meet regularly to coordinate services, develop a common set of outcomes, and collaboratively decide upon and implement plans to foster the well-being of young people. The coordinating bodies are asked to participate in the State Child and Youth Policy Coordination Survey in odd years. This is the first comprehensive biennial survey of state child and youth policy coordinating bodies. These entities work across agency lines to coordinate services and foster the well-being of children and youth. The survey assesses coordinating bodies along criteria derived from the Ready by 21® Leadership Capacity Standards, which are organized into the four Building Blocks for Effective Change: (1)broader partnerships; (2) bigger goals; (3) better data; and (4) bolder actions.
