This paper outline the interim findings from research into the cost effectiveness of employment supports for disabled people, specifically those commissioned by local authorities and the NHS, primarily for people with learning disabilities and people with mental health problems. The research is being undertaken by the National Development Team for Inclusion (NDTi) and funded by the School for Social Care Research – part of the National Institute for Health Research. This paper summarises the work up to around half-way through the study, highlights some initial findings, and also re-reports on an earlier scoping study on the evidence of effectiveness of employment supports undertaken by NDTi for the same funding body.
