This study examines the effectiveness of correctional education for adults and for juveniles, and the challenges associated with this programming. Five chapters are contained in this report: introduction; whether correctional education for incarcerated adults is effective; a systematic review of correctional education programs for incarcerated juveniles—results for corrective reading, computer-assisted instruction, personalized and intensive instruction, other remedial instruction programs, vocational/career technical education, and GED completion; RAND Correctional Education Survey—results for correctional education programs today, funding and the impact of the 2008 recession, postsecondary education, use of technology and preparedness for implementation of the 2014 GED exam, and outcome indicators and postrelease measures of success; and conclusion and recommendations. "The results of the meta-analysis are truly encouraging. Confirming the results of previous meta-analyses—while using more (and more recent) studies and an even more rigorous approach to selecting and evaluating them than in the past—the study shows that correctional education for incarcerated adults reduces the risk of postrelease reincarceration (by 13 percentage points) and does so cost-effectively (a savings of five dollars on reincarceration costs for every dollar spent on correctional education). And when it comes to postrelease employment for adults—another outcome key to successful reentry—researchers find that correctional education may increase such employment … Overall, this study shows that the debate should no longer be about whether correctional education is effective or cost-effective but rather on where the gaps in our knowledge are and opportunities to move the field forward" (p. iii-iv).
