Using a randomized experimental design, this study evaluated the effectiveness of the Minnesota Comprehensive Offender Reentry Plan (MCORP), an offender reentry pilot project implemented in 2008. In an effort to reduce recidivism, MCORP attempted to increase offender access to community services and programming by producing greater case management collaboration between caseworkers in prison and supervision agents in the community. The results showed that MCORP significantly improved employment rates, decreased homelessness, broadened offenders' systems of social support, and increased the extent to which offenders participated in community support programming (mentoring, restorative justice services, and faith-based programming). The findings further revealed that MCORP significantly reduced all three types of reoffending (rearrest, reconviction, and new offense reincarcerations) but did not have a significant impact on supervision revocations for technical violations. The evidence suggests that MCORP was effective in decreasing reoffending largely because it increased the extent to which offenders were employed, involved in community support programming, and able to develop systems of social support.
