The Office of Justice Programs' (OJP) CrimeSolutions.gov uses rigorous research to determine what works in criminal justice, juvenile justice, and crime victim services. CrimeSolutions.gov is intended to be a central, reliable resource to help practitioners and policymakers understand what works in justice-related programs and practices. Its purpose is to assist in practical decision making and program implementation by gathering information on specific justice-related programs and practices and reviewing the existing evaluation and meta-analysis research against standard criteria. It is important to note the CrimeSolutions.gov Web site does not constitute an endorsement of particular programs or practices. The programs reported upon favorably are being recognized for their accomplishments in support of the mission of the OJP. Furthermore, it is not intended to replace or supersede informed judgment and/or innovation. CrimeSolutions.gov recognizes that rigorous evaluation evidence is one of several factors to consider in justice programming, policy, and funding decisions. OJP also recognizes the importance of encouraging and supporting innovative approaches that may not yet have extensive evidence of effectiveness.
