An institution for young offenders up to the age of 17. They are run by private operators according to Home Office contracts, which set out detailed operational requirements. They house vulnerable young people who are sentenced to custody in a secure environment where they can be educated and rehabilitated. They differ from Young Offender Institutions (YOIs) in that they have a higher staff to young offender ratio (a minimum of three staff members to eight trainees) and are smaller in size, so that individuals' needs can be met more easily. The regimes are constructive and education‐focused. They provide programmes tailored for young offenders that give them the opportunity to develop as individuals which, in turn, will help stop them reoffending. Trainees are provided with formal education 25 hours a week, 50 weeks of the year. All services are provided on‐site, including all education and training, primary healthcare, dentistry, and services to address the young person's offending behaviour (including input from mental health and social care professionals). They can also be used to house people remanded to local authority accommodation.
