The Pay for Success – Criminal Justice assessment tool (PFS-CJ) is a scoring rubric designed to help PFS planners assess a program’s suitability for PFS and identify specific elements of the program that need to change to become PFS-ready. The tool includes criminal justice-relevant examples showing how lessons learned from the first generation of criminal justice PFS projects in the US can combine with Urban’s broader PFS assessment tool to create a useful litmus test for identifying future PFS projects.
