The Office of Juvenile Justice and Delinquency Prevention's (OJJDP's) Model Programs Guide (MPG) contains information about evidence-based juvenile justice and youth prevention, intervention, and reentry programs. It is a resource for practitioners and communities about what works, what is promising, and what does not work in juvenile justice, delinquency prevention, and child protection and safety. MPG uses expert study reviewers and CrimeSolutions.gov's (NCJ 249684) program review process, scoring instrument, and evidence standards. The two sites also share a common database of juvenile-related programs. MPG is an easy-to-use program database established to assist practitioners, policymakers, and communities in identifying and implementing programs that can make a difference in the lives of children and families. It addresses a range of issues including child victimization, substance abuse, youth violence, mental health and trauma, and gang activity. In addition to providing program profiles, MPG contains useful literature reviews, implementation information, and links to additional resources that practitioners, policymakers, and communities can use to improve the effectiveness of interventions, enhance accountability, ensure public safety, and reduce recidivism. The tools provided on MPG are specifically designed for juvenile justice-oriented practitioners and policymakers.
