This study investigated the roles of education in the rehabilitation and reformation of inmates of Jos prison. The paper was of the view that the rehabilitation of prisoners through formal education is necessary. The study adopted the descriptive research design. Therefore, a 23-item questionnaire was developed and administered to 250 respondents comprising of 150 inmates and 100 staff of Jos Prison who were chosen through stratified random sampling. The result showed that the greater number of the respondents agreed that formal education for prisoners is very important in the rehabilitation and reformation of inmates. Also, some challenges militating against the smooth operation of formal education in Jos prison was highlighted. Based on the finding, the paper recommended that formal education should be made compulsory for inmates. There should be special incentives for the prison staff that are responsible for the educational sector, this would go a long way in bettering the general conditions of inmates for effective rehabilitation and reformation/reintegration, it will also discourage high rate of prisonalization and recidivism.
