This article presents selected findings of a study of the provision of reintegration support for prisoners leaving custody in Ireland undertaken by the authors for the Irish Penal Reform Trust. It argues that provision of certain support such as accommodation has improved significantly in recent years, but some important difficulties remain. Considering the sharp increase in the number of people in custody in Ireland, the authors argue that investment in post-release support should form the central part of the State’s response to the rise in prison population.
