MAPPA are a set of statutory arrangements under which the Police, Probation and Prison Services (known as the responsible authority) in each of the 42 Areas in England and Wales are required work with other relevant local agencies, such as children and social services, health and housing authorities, in order to manage the risk posed by specified sexual and violent offenders. They were introduced in 2001.  

Drawing upon the expertise of the various agencies, MAPPA allow relevant offenders to be identified, information to be shared, risk assessments and actions plans to be agreed and for those action plans to be reviewed and amended as necessary. Work within MAPPA may result, for example, in increased police monitoring, special provision for victim protection, the disclosure of information to others to enhance public protection, close supervision and appropriate accommodation. Information about how MAPPA works locally is available in the form of the MAPPA annual reports published by the responsible authority.
