The first edition of this publication was released in 2011. As pretrial services have redefined its goals and strategic objectives, so must its outcome and performance metrics change. To that end-and to ensure that metrics for the field continue to be developed by practitioners-NIC commissioned PEN to assess the current pretrial landscape and revise current metrics to match these new dynamics. This process included internal discussion by PEN members and input via a survey from pretrial services agency directors whose agencies collect performance metrics. PEN member discussions and the survey focused on which measures “work” in the real world, which were problematic, and what other data should be considered to gauge agency outcomes. The metrics presented here reflect this feedback. Outcomes are now tied to the three principles of bail-maximizing release, court appearance, and public safety-and a more refined definition of system “success” in meeting these objectives. Included commentary discusses how changes in the pretrial landscape over the past decade have helped redefine outcome and performance metrics.
