This report discusses the findings of a survey of 45 supported employment providers that sought to identify potential barriers to supported employment services for persons with severe physical disabilities. Results are compared with survey results from 50 state vocational rehabilitation (VR) agencies. Key findings from the survey include: (1) the percentage of persons with severe physical disabilities served by the supported employment providers increased from 28 percent in 1989 to 30 percent in 1990; (2) the total number of persons with severe physical disabilities increased by 31 percent from 1989 to 1990; (3) persons with severe physical disabilities were less likely to be served in the individual placement model with supported employment providers compared with the percentage reported by state VR directors; (4) 10 percent of providers were working concurrently in segregated settings and in integrated, supported employment programs; and (5) barriers to supported employment include transportation issues, lack of personal care services, and federal requirements. The need for federal supported employment regulations to be modified and support service resources to be expanded is discussed. Appendices include the survey instrument and a list of service provider respondents. (Contains 22 references.) (CR)
