The research calculated the reconviction rates of MAPPA-eligible offenders released from custody from 2001 to 2004. These were compared to the reconviction rates of offenders released from 1998 to 2000 who, given their index offence and sentence length, would have qualified for MAPPA had it been in operation.
Results illustrated that offenders subject to MAPPA management had a lower rate of reconviction than those released prior to MAPPA implementation.
Although the methodology used in this study cannot be used to evaluate the impact of MAPPA, results suggest that it may have made a positive contribution to the assessment and management of dangerous offenders in relation to reconvictions. They lend support to policies which expanded and standardised multi-agency work.
