This report details the findings of a survey of supported employment directors in the 50 state vocational rehabilitation (VR) agencies, that sought to identify potential barriers to a variety of supported employment services for persons with severe physical disabilities. Key findings include: (1) 84 percent of the agencies provided services to persons with severe physical disabilities during FY 1989, an increase over the previous year; (2) the number of persons with severe physical disabilities in supported employment increased by 27 percent from FY 1988 to FY 1989; (3) the individual placement model is the option utilized most often; (4) a number of transportation issues present major barriers to employment, including availability, accessibility, and affordability; (5) although respondents reported that personal care assistance supports are available initially at the job site for workers with severe disabilities, fewer resources are available following VR case closure; (6) no specific state agency is mandated to provide long-term support services, making the provision of ongoing supports difficult to arrange; and (7) the job training requirement of twice per month and the 20 hour per week minimum requirement are impediments for this population. An appendix includes the survey instrument. (Contains 21 references.) (CR)
