Supported employment began in the USA and then spread to other countries such as the UK. According to the O’Bryan et al (2000)
"Initially this form of supported employment focussed primarily on people with learning difficulties. In recent years, however, many agencies have become more generic, working with a much wider range of people, including those with long-term mental health needs."
In the UK a specialised, autism-specific supported employment service, Prospects, was set up in 1974 in collaboration with The National Autistic Society, St George's London University, and the Employer's Forum on Disability in 1994.
The National Autistic Society no longer provides a supported employment programme but there are a number of national and local organisations which do run supported employment programmes.
