Building upon the 2021 report titled The Effect of Prison Industry on Recidivism: An Evaluation of California Prison Industry Authority (CALPIA), this study 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, this 2023 report is a comparison within CALPIA programs only.
This UCI study has also been incorporated into a report published by CALPIA.
