Details
From 19 July 2021, HM Prison and Probation Service (HMPPS) launched a new transitional accommodation service, Community Accommodation Service Tier 3 (CAS3), providing up to 12 weeks basic accommodation with basic support for those leaving prison at risk of homelessness.
The service was initially launched across five probation regions and achieved national coverage across all twelve probation regions in December 2023.
This impact evaluation was conducted to help understand the effect of CAS3 on reoffending, accommodation and employment outcomes for men who access the service.
