This study was conducted to delineate some of the characteristics of disabled clients which contribute significantly to success in vocational programs. The performance of disabled persons in three types of vocational settings (college, skill training, and work evaluation/work experience samples) was examined to determine if the factors contributing to objective measures of success varied as a function of the program demands or the clinet/student's initial abilities. An additional part of the project was devoted to a follow-up of clients who had been placed in employment in order to gauge their long-term stability and factors which potentially relate to their maintenance of employment. The 82 subjects were interviewed and observed in their programs and assessments were made of their: (1) work assets, (2) goals, (3) disability, (4) degree of interpersonal support from family and friends, (5) attitude toward disability, (6) interpersonal dominance, (7) locus of control, (8) ability to manage others, and (9) performance in the vocational setting. The over-all results were interpreted to mean that success for disabled persons is determined by different factors over the long process of vocational readiness. Criteria of success early in training are advancement to better training, and this requires job skills and a positive attitude toward work. However, later success requires the additional factor of emotional stability. (SB)
