This textbook brings together for the first time theory, policy and skills relevant to working in a multi agency setting within the criminal justice system. It comes at an important time as the professional qualifying arrangements for probation officers are changing, along with the development of a mixed economy of correctional practice. The book outlines the legislative and policy framework in the criminal justice system, and evaluates professional and organisational conflicts within multi agency contexts as well as highlighting key offender groups, and issues associated with desistance from crime. It is essential reading for all students and practitioners involved in or studying correctional work, through the Probation or Prison services, or other agencies.About the Author: Aaron Pycroft, Institute of Criminal Justice Studies, University of Portsmouth and Dennis Gough, Institute of Criminal Justice Studies, University of Portsmouth
