As pretrial programming has expanded in Wisconsin and across the country, it is essential that program managers have the ability to measure progress and track outcomes to ensure that they are meeting established justice system goals. In order to support these efforts, it is important to define specific, measurable outcomes, and their associated indicators. This document is intended to help define such measures and explain the data elements necessary to accurately quantify each one. Where necessary, mathematical equations are provided to support data collection and reporting. Arnold Ventures, LLC, creator of the Public Safety Assessment (PSA), recommends that jurisdictions using the PSA track specific pretrial outcomes including failure to appear (FTA), new criminal activity (NCA), and new violent criminal activity (NVCA). Additionally, other outcomes such as adherence rate, overall compliance rate, and the average length of pretrial detention for defendants prior to initial release may be beneficial to track.
