Rising prison numbers and high rates of re-offending illustrate the need for criminal justice reform. In the social care sector, the ‘personalisation revolution’ has resulted in the near eradication of long-term, institutional care for the majority of people with disabilities and many frail older people, increasing satisfaction. This paper examines what this has entailed and considers the case for introducing personalisation in the criminal justice system. It concludes that criminal justice reformers can learn from the social care experience and suggests how personalisation might fit within the current criminal justice reform agenda. However, introducing personalisation will pose significant challenges, perhaps the biggest being the need to change criminal justice culture.
