Reset, also known as the Intensive Resettlement and Rehabilitation Project, is a paid mentoring scheme for prisoners leaving custody introduced by the Probation Board of Northern Ireland in March 2014 and funded through the Northern Ireland Executive Change Fund. The mentoring service, which is delivered by NIACRO, supports the work of Probation Officers and specifically assists mentees at the critical stage of transition from custody to the community. It offers practical support, bespoke to each mentee, supporting an explicit desistance approach. This paper describes the development of Reset and its implementation in Northern Ireland from 1 March 2015 to 31 March 2016, and outlines the results of an independent evaluation carried out by the Northern Ireland Statistics and Research Agency.
