The four measures of recidivism were new arrests, new convictions, any incidence of reincarceration, and returns to prison with a new sentence. In addition, a detailed analysis of recidivism rates for selected offender groups is provided. The study found recidivism in Connecticut to be generally consistent with other States for the categories of recidivism that were reported. As in past studies at both the State and national level, offenders who were discharged after completing community supervision, such as parole or transitional supervision, had the lowest recidivism rates among all groups of offenders in the study. Although 36.6 percent of all offers were reincarcerated for new sentences within 3 years of release, 27.9 percent of offenders completing transitional supervision and 24.7 percent of offenders completing parole were reincarcerated for new sentences. Within 3 years of their release or discharge, 67.5 percent of offenders were rearrested; 53.7 percent were convicted for a new criminal offense; 56.5 percent were returned to prison with new charges for either technical violations or to begin a new prison sentence; and 36.6 percent were reincarcerated to serve a new prison sentence. A history of probation violation was a predictor of increased recidivism. Of those offenders who had a history of two or more convictions for probation violations prior to their 2005 release or discharge, almost 50 percent returned to prison for a new sentence within 36 months. Among offenders with no history of probation violation prior to their release, only 27.3 percent returned within 36 months.
