A “White Paper” (102 pages) synthesizes and distills the research on what works to reduce recidivism and improve outcomes for youth in the juvenile justice system. They also provide examples illustrating how state and local juvenile justice officials in the US have established particular policies and system interventions to implement these principles. Recognizing that improved outcomes are possible only when research on what works is implemented with fidelity, Part Two of the paper details lessons learned from research and practice on how to implement the principles effectively, and provides examples of how state and local juvenile justice systems have operationalized the principles in practice.
