The book is an essential resource for people working within the youth justice system, those training to work in youth justice, and students taking courses in youth justice as part of criminology or criminal justice degrees. Providing a comprehensive and up-to-date review of research and the implications for practice, it is designed to meet the needs of students taking YJB sponsored courses with the Open University, in particular K208 (the Professional Certificate in Effective Practice) which forms part of a wider Foundation Degree.
