Book excerpt: This book explores the journey of young people through a Secure Training Centre and, more generally, the criminal justice system in the UK. It examines the extent to which young people have been failed by the system at every stage of their lives, with incarceration used as a means of removing ‘the problem’ from society. To explore this process, the authors utilise an integrated theoretical framework to develop a new rehabilitative approach focused on developing positive outcomes for young people. The book deploys a social impact measurement methodology to evaluate the experience and outcomes of youth justice interventions at a Secure Training Centre. Such an approach provides a fresh perspective on the youth justice debate which has traditionally utilised outcome data to measure immediate impact relating to recidivism and is therefore not focused on the young person holistically. Using a social impact framework to evaluate youth justice, underpinned by an integrated theoretical framework, allows for assessment to be made which place the young person at the centre of evaluation.
