This study was undertaken to determine if variations in the quality of vocational education offered in prisons, and the skill level developed by participants in these programs, are related to the inmates' post-release adjustment. It proved difficult to execute the study as designed, and the collected data were neither as numerous nor as complete as originally planned. Although it was possible to identify several variables that predict a former inmate's life satisfaction and encounters with the law, the evidence did not clearly demonstrate that particular aspects of a prison vocational education program have an effect on the post-release experiences of former inmates. The generally negative findings in this study do not suggest that vocational training in prison is ineffective. Rather, they indicate that we do not know what features of the training make it more or less effective.
