Insufficient Evidence List: Programs Reviewed but Not Rated uses rigorous research to inform practitioners and policy makers about what works in criminal justice, juvenile justice, and crime victim services. We set a high-bar for the scientific quality of the evaluations we review in order to assign a program’s final rating. Due to these high standards, many evaluations do not meet our minimum rating criteria. As a result, we are unable to determine a final rating for the program based on this insufficient evidence.

Programs are not placed on the insufficient evidence list because of weaknesses in the programs themselves. Instead, our reviewers determined that the available evidence was insufficient for a program rating to be assigned.

We post this list so that policy makers, practitioners, program developers, and researchers can see the full breadth of programs that we have reviewed for This list also demonstrates the need for additional evaluation research in order to improve the evidence base for these programs.
