California Prison Industry Authority (CALPIA) is a self-supporting training and production program currently operating within the California Department of Corrections and Rehabilitation (CDCR). CALPIA provides training, certification, and employment to inmates in a variety of different fields. The goods and services produced by CALPIA are sold to the state and other government entities, which provides an economic benefit to the state. In addition to the vocational and economic aspect of the program, one of CALPIA’s missions is to reduce the subsequent recidivism of their inmate participants. In 2021, the Center for Evidence-Based Corrections prepared a report on the recidivism outcomes for individuals who had participated in CALPIA programs for at least six months (Hess and Turner, 2021). That report examined the effect of participation in CALPIA on the recidivism of CDCR inmates by comparing CALPIA participants with at least 6 months in the program and released between August 2014 and July 2018 with inmates who were accepted into the CALPIA program but were released before they could actively participate (i.e., the “Waitlist” group). That report found that participation in CALPIA was associated with reduced offending. CALPIA individuals had lower rates of arrests, conviction, and incarceration during a three-year follow-up than a Waitlist comparison group. Although the sample size for our analysis of Career Technical Education (CTE) was small, participation in this CALPIA program yielded lower recidivism rates than other CALPIA program participation. This report further analyzes the sample of individuals who participated in CALPIA programs by separating the CALPIA programs into thirteen different groups, placing similar programs together. Thus, it is a comparison within CALPIA programs only. The analysis strategy is the same as used in our previous report: we examine arrest, conviction and return to custody calculated at one-, two- and three-year post release for the individuals. Propensity score analyses were used to adjust for baseline differences in the groups. Our findings suggest that the enterprise programs perform about equally well with the exception of CTE, which appears to do slightly better than other enterprises. We also found a positive effect for CTE in our earlier report. Several other programs show patterns of higher or lower recidivism which are suggestive but not conclusive due to lack of statistical significance. We note that small sample sizes, using propensity score analyses, may have limited our ability to detect significant differences.
