Other Clearinghouses

The table below lists several government and private organizations that maintain databases similar to and that identify what works in other disciplines.

The programs contained in these databases may or may not overlap with those found on When a program on does appear in another database, we note that on the program's summary page.

Promising Practices Network RAND Corporation and these other clearinghouses are complementary resources. 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

Resources on Programs, Practices and Decision-Making

Are you interested in implementing programs or conducting program evaluations? If so, the following material should be of interest:

Being Smart on Crime With Evidence-Based Policing
In this National Institute of Justice NIJ Journal article from March 2012, 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.

Understanding Evidence, Part 1. Best Available Research Evidence: A Guide to the Continuum of Evidence of Effectiveness
In this guide, the Centers for Disease Control and Prevention aims to explain the purpose and meaning of the Continuum of Evidence of Effectiveness, a tool that was developed to facilitate a common understanding of what the Best Available Research Evidence means in the field of violence prevention. This Continuum also serves to provide a common language for researchers, practitioners and policymakers in discussing evidence-based decision-making.

Evidence Integration at the Office of Justice Programs

OJP's Evidence Integration Initiative is focused on improving the synthesis and translation of social science research findings to inform practice and policy in criminal justice, juvenile justice and victim services. accomplishes this primarily by assessing the quality and findings of program evaluation evidence to try to answer the question, "Does this program work?"

To examine this broad base of research and statistical findings and seek answers to a range of practical policy questions, OJP partnered with the Office of Community Oriented Policing Services and the Office on Violence Against Women to create two internal Evidence Integration Teams, which focused on two topic areas: gangs, and children exposed to violence. These topical areas were selected because they present significant challenges for the field and are priorities for OJP. Included in the resources below are highlights of the findings from these Evidence Integration Teams.
