This joint strategy brings together the Welsh Government and Youth Justice Board’s vision and commitment to improve services for children and young people from Wales at risk of becoming involved in, or who are in, the youth justice system.  It provides the Welsh Government, Youth Justice Board and those delivering youth justice services with a coherent framework through which the prevention of offending and re-offending by children and young people can be achieved.  It builds on the approach and achievements delivered under the All Wales Youth Offending Strategy 2004 (AWYOS), and its subsequent Delivery Plan 2009.
