HM Prison Gartree was established in 1965 as a male training prision and part of the high security system. From 1992 it's focus shifted to caring for prisoners with life sentences. The Gartree Therapeutic Community was established in 1993. It provides a long term, residential, offending behaviour intervention for men who have a range of offending behaviour risk areas and longstanding personality, emotional or psychological problems. The Community provides an open living-learning experience for its members who are empowered to make their own decisions. All aspects of their behaviour is open to challenge within a therapeutic environment. The Community has 25 beds with a group-based setting where community members can undertake therapy. In 2013 the unit expanded offering 12 beds in the seperate TC+, a therapeutic community for those with Learning Disabilities. TC+ operated along a simular model to the mainstream Community but the approach was adapted to support prisoners with learning disabilities and/or an IQ of under 80 to access therapy.
