This study provides insight into the postrelease performance of all former inmates with available data who were released from a prison in New Jersey in 2006 ( N = 12,187). Three indicators of recidivism are considered: (a) an arrest for a new crime, (b) a conviction for a new crime, and (c) a technical parole violation. Individuals are categorized into groups according to the release mechanism that they experienced: discretionary parole, mandatory parole, or unconditional release. Multivariate analyses utilize Cox proportional hazards survival tests. Results indicate that after approximately 3 years of follow-up time, those released to supervision were generally less involved in new crimes when compared with those who were released unconditionally. However, a high proportion of those who were paroled recidivated shortly after release, and the predicted probability that a former inmate would recidivate did not substantially differ between release groups in the presence of statistical controls.
