Inclusive and equitable quality education for all have being a major concern for countries around the world, as it is capture as part of the year 2030 agenda for sustainable development, specifically in sustainable development goal 4. While international organizations and governments around the world have been making effort in promoting and enhancing literacy among citizens including adults, however, literacy rate among adult populations in most developing countries including Nigeria seems alarming, as considerable portion of Nigeria’s adult population, especially those residing within the rural areas finds it difficult to read, write and do simple arithmetic operations. High level of illiteracy results in poor employment opportunities as well as low income, low self-esteem and higher crime rates. While crime is an inevitable occurrence in societies, prisons exist to protect societies from criminals as well as deviants, whose actions portend threats to societal functioning. Although, prisons are mainly established for protecting societies; reformation and rehabilitation of the convicted prisoners are key functions of all correctional institutions, and education plays crucial role in the rehabilitation process. Thus, this study advocates the inclusion of adult education programmes such as peace education, adult literacy, environmental adult education, civic and political education in Nigerian correctional institutions, as a way of minimizing high incidences of recidivism, as well as ensuring pro-social attitudes and behaviours required from prisons’ inmates, after serving jail terms. The requisite knowledge in adult education programmes, becomes a source of potential benefits to community sustainability, as ex-prisons’ inmates can make effective contributions through knowledge acquired, in achieving the desired socio-economic and environmental sustainability in Nigerian communities.
