The Colorado Pretrial Assessment Tool (CPAT) is an empirically-based pretrial risk assessment tool developed to inform bond decisions in Colorado. The tool measures a defendant’s risk of failure to appear (FTA) or re-arrest while released pretrial. The overall goal of this study was to examine and validate the current CPAT, and based on feedback from multiple criminal justice stakeholders, construct and pilot a revised version of this tool, the CPAT-Revised (CPAT-R). The study was completed between January 2018 and June 2020 and included three phases. This report will detail the methodology and results of all three phases of this study.
