The National Institute of Justice’s CrimeSolutions data can be used to help policymakers inform funding decisions, trainers improve their training programs, and researchers become more informed on criminal justice research. CrimeSolutions is comprised of two components — a web-based clearinghouse of programs and practices and a process for identifying and rating those programs and practices. After the programs and practices undergo 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.
