The vocational rehabilitation agencies in Region V (Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin) cooperated in a study to determine whether there were systematic gender differences along input, program, and output dimensions among the state vocational rehabilitation programs in the region over a 13-year period, 1972-1984. The interdependence of gender, as well as fiscal year, on selected state-level indexes of client characteristics, service delivery, and program impact was examined using a study group approach. Data for the study were drawn from the R-300 data files that are submitted annually by each state agency to the Rehabilitation Services Administration. The study found important differences in characteristics, service patterns, and outcomes and impacts of the vocational rehabilitation program as between men and women in the region. The results indicate a serious problem of inequity in the impacts of the vocational rehabilitation program on men and women with disabilities. The research clearly demonstrated that women with disabilities did not acquire financial resources and occupational success at the conclusion of rehabilitation comparable to those achieved by men. The research raised issues regarding outcomes, inputs, processes, and systemic changes, and recommendations were made to address the problems found in these areas. (KC)
