US National Institute of Justice’s Crime Solutions Evidence Base

The US based National Institute of Justice’s Crime Solutions uses proven research to determine what works in criminal justice, juvenile justice and crime victim services.

It is comprised of two components — a web-based clearinghouse of programs and practices and a process for identifying and rating those programs and practices.

The clearinghouse presents programs and practices that have undergone rigorous evaluations and meta-analyses. The site assesses the strength of the evidence about whether these programs achieve criminal justice, juvenile justice, and crime victim services outcomes in order to inform practitioners and policy makers about what works, what doesn't, and what's promising.

The programs and practices presented on CrimeSolutions.gov are identified, screened, reviewed, and rated using a standardized process. Programs are reviewed based on evaluations and practices based on meta-analyses that synthesize different evaluations, but those evaluations have to be sufficiently rigorous. Each screened program and practice is reviewed by two certified reviewers using objective scoring instruments. Ratings are assigned based on the consensus score, which is subject to a documented dispute resolution process when necessary. Learn more about the rating process for programs and practices.
