Decisions on pre-release programmes are made by the Minister or senior officials of the Irish Prison Service on his behalf. Review meetings are held regularly in each prison institution to facilitate the exchange of information and aid decision making in the management of offenders' sentences. Each meeting is chaired by the governor or deputy or assistant governor of the institution in question and is attended by senior prison management, probation and welfare service staff, chaplains, teachers, other prison staff and an official from the Irish Prison Service headquarters. Where an offender is engaging with other services in the prison, such as the psychology or psychiatry service or other medical services, the professional dealing with the specific offender will also be invited to attend when required.
