The arts have a long history of success within the criminal justice system in Scotland. The work of numerous individual artists and arts organisations – from the special unit at Barlinnie, the readers in residence programme to the recent Inspiring Change initiative – have done a great deal to demonstrate the effectiveness of the arts in justice settings. In this publication we have gathered together a few examples of recent projects which have had a significant impact in Scotland, and some persuasive facts and figures from programmes further afield. The case studies show that the arts matter in prisons. They cannot single-handedly prevent re-offending but they do contribute towards changing hearts and minds: by increasing reflectiveness, enhancing self confidence and encouraging the acquisition of transferable skills, the arts make a difference to individuals and contribute towards their rehabilitation.
