Rehabilitation is the process of re-educating and retraining those who have committed a crime. It generally involves psychological approaches which target the cognitive distortions associated with specific kinds of crime committed by particular offenders – but may also involve more general education such as literacy skills and work training. The goal is to re-integrate offenders back into society. Methods A successful rehabilitation of a prisoner is also helped if convicted persons: are not placed in health-threateningly bad conditions, enjoy access to medical care and are protected from other forms of serious ill-treatment, are able to maintain ties to the outside world, learn new skills to assist them with working life on the outside, enjoy clear and detailed statutory regulations clarifying the safeguards applicable and governing the use and disposal of any record of data relating to criminal matters.

Rehabilitative measures involve education, job training, workshops to acquire a trade, and therapy along with the humane treatment they receive from personnel who have to complete three years of training to become prison guards. The effectiveness of Norway's methods is evident as they hold the lowest recidivism rate worldwide at 20% as of December 2014. In comparison, in 2007, 14 prisons in England and Wales had reconviction rates of more than 70%, which cost an average of £40,000 a year for each prisoner. This has been accused of being "a huge investment in failure" and a "a total lack of consideration for potential future victims of released prisoners".
