With funding from the National Institute of Justice, this study aims to provide a national portrait of prosecutor-led diversion programs through case studies of diversion programs in 11 prosecutor's offices. In recent years, a growing number of prosecutor's offices have established pretrial diversion programs as an alternative to traditional case processing. The mostly large, high-volume programs examined for this study were intentionally selected to provide for variation in program timing (pre- and post-filing), target population, program intensity and duration, and other factors. Research for this study was undertaken in collaboration with the RAND Corporation, the Association of Prosecuting Attorneys, and the Police Foundation.
