CrimeSolutions is intended to be a central, reliable resource to help practitioners and policymakers understand what works in justice-related interventions (both 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 website does not constitute an endorsement of particular programs or practices. Furthermore, it is not intended to replace or supersede informed judgment and/or innovation. CrimeSolutions recognizes that rigorous evaluation evidence is one of several factors to consider in justice programming, policy, and funding decisions. NIJ also recognizes the importance of encouraging and supporting innovative approaches that may not yet have extensive evidence of effectiveness.

CrimeSolutions is operated by the National Institute of Justice with additional funding from the Office of Juvenile Justice and Delinquency Prevention.
No! CrimeSolutions is a resource to assist justice practitioners and policy makers in using evaluation evidence for practical decision making and program implementation. CrimeSolutions not intended to be an exhaustive list of worthy and unworthy investments. The Office of Justice Programs and its components also recognize the importance of supporting innovative approaches and practices that may not yet have extensive evidence of effectiveness.

OJJDP’s Model Programs Guide (MPG), which predates the June 2011 launch of CrimeSolutions, focuses specifically on programs related to the juvenile justice system and covers the entire continuum of youth services from prevention through sanctions to reentry. CrimeSolutions serves a broader scope focusing on what works in criminal justice, juvenile justice, and crime victim services.
After the launch of CrimeSolutions, OJJDP began a re-review of MPG programs using the evidence standards and criteria developed for CrimeSolutions (see Program Review and Rating from Start to Finish and Scoring Instruments to learn more about this review process). Beginning in October 2013, the juvenile program information contained on CrimeSolutions and the MPG site will be completely aligned and will share program profiles. The existence of the two separate sites remains, though, because MPG also captures additional resources and tools that are specifically tailored to meet the needs of the juvenile justice field, including literature reviews and implementation guides.
OJJDP and the National Institute of Justice (NIJ), the sponsor of CrimeSolutions, are both components of the Office of Justice Programs (OJP), U.S. Department of Justice.
The table below lists several government and private organizations that maintain databases similar to CrimeSolutions and that identify what works in other disciplines.
The programs contained in these databases may or may not overlap with those found on CrimeSolutions. When a program on CrimeSolutions does appear in another database, we note that on the program's summary page.
| Program Library | Sponsoring Agency/Organization |
|---|---|
| Guide to Community Preventive Services | U.S. Department of Health and Human Services, Centers for Disease Control and Prevention |
| Model Programs Guide | U.S. Department of Justice, Office of Juvenile Justice and Delinquency Prevention |
| National Mentoring Resource Center | U.S. Department of Justice, Office of Juvenile Justice and Delinquency Prevention |
| What Works Clearinghouse | U.S. Department of Education, Institute of Education Sciences |
| Program Library | Sponsoring Organization |
|---|---|
| Blueprints for Healthy Youth Development (formerly Blueprints for Violence Prevention) | University of Colorado, Center for the Study and Prevention of Violence |
| Campbell Collaboration Library of Systematic Reviews | The Campbell Collaboration |
| Evidence-Based Policing Matrix | George Mason University, Center for Evidence-Based Crime Policy |
CrimeSolutions and these other clearinghouses are complementary resources. CrimeSolutions has a more general focus that includes all of criminal justice, juvenile justice, and crime victim services. The clearinghouses each have differing but related or narrower focuses. As examples:
- The U.S. Department of Education's What Works Clearinghouse addresses the evidence base related to programs, products, practices and policies in education.
- The Model Programs Guide focuses on programs related to the juvenile justice system and covers all aspects of youth services, from prevention through sanctions to reentry.
In most cases, the clearinghouses use different systems and processes to rate their programs. The exceptions to this are the OJJDP-funded Model Programs Guide and National Mentoring Resource Center, which use the same rating methodology and instruments as CrimeSolutions.

Plan for Program Evaluation from the Start
In this National Institute of Justice NIJ Journal article emphasizes the importance of planning and designing the evaluation of a program before beginning the program's implementation. It goes on to discuss the benefits and features of planning, designing, and timing a program's evaluation.
Being Smart on Crime With Evidence-Based Policing
In this National Institute of Justice NIJ Journal article, Chief Jim Bueermann (Ret.) reflects on how law enforcement agencies can do a better job of using science to reduce crime by adopting evidence-based policing as a standard practice and by partnering with universities or colleges. Evidence-based policing leverages the country's investment in police and criminal justice research to help develop, implement and evaluate proactive crime-fighting strategies that may prove more effective and less expensive than the traditional response-driven models.
Is This a Good-Quality Outcome Evaluation Report? A Guide for Practitioners
This guide was produced by the Justice Research and Statistics Association and the Bureau of Justice Assistance to provide practitioners with a basis for distinguishing the differences between good- and poor-quality evaluation reports.
Understanding Evidence
This free online resource developed by the Centers for Disease Control and Prevention offers practitioners, and others working to prevent violence, some important knowledge and resources for using evidence in their decision-making processes. This site is designed primarily for violence prevention practitioners, but anyone working to prevent violence in their communities will find the information useful.
The information and evidence ratings included on CrimeSolutions are not static. As additional programs and practices are identified and new research becomes available, CrimeSolutions content will be updated and supplemented to reflect the most current programmatic and research information available. We also rely on users to provide us with critical feedback about the CrimeSolutions website itself. What is useful and what is not? What additional features would you like to see on the site in the future? CrimeSolutions users are welcome to Submit Feedback.
Specific concerns about evidence ratings or information contained within CrimeSolutions may also be submitted via the Submit Feedback online form. If necessary, changes to the information presented on the site will be made, per the processes outlined in Inquiring About or Appealing an Evidence Rating.
CrimeSolutions does not provide direct services. However where available, we list contact information in the profile for each program and practice. If you are unable to locate this information on our site, please contact us with the title of the program or practice you are interested in, and we will do our best to provide the contact information you are seeking.
Although reviews are conducted on an ongoing basis, CrimeSolutions is not an exhaustive list of all justice-related programs and practices. If you cannot find the program or practice you are looking for, then you can do the following:
- Search for programs or practices that address similar outcomes using filters on the program and practice lists.
- Review the list of programs that have been considered but not rated . If the program is on this list, it means that the evaluation(s) associated with that program did not meet our criteria for review or inclusion.
- Review the list of practices that have been considered but not rated . If the practice is on this list, it means that the evaluation(s) associated with that program did not meet our criteria for review or inclusion.
- Nominate that program or practice in question for review.
