15.1 The Prison Service is one of the three agencies that form the MAPPA Responsible Authority and has a critical role to play in the management of MAPPA offenders. The Prison Service is required to provide information on MAPPA offenders at key points in their sentence and on release. Prison staff will have recorded a wealth of information about the prisoner that will be used to inform the plans for their release. This includes information about the offender's behaviour in custody, security intelligence, engagement in accredited programmes and employment or education related activities, and contact made with others, either in custody or the community. The Prison Service contributes to release planning and MAPPA level setting processes.
