This study investigated the effects of supported employment on wages earned by persons with disabilities. We sought to determine whether supported employment produced higher wages than sheltered employment, whether any effect was a result of increases in wage rates or hours, and whether one model of supported employment had more impact than another. The analysis showed that wages increased after entering supported employment, after correcting for differences in employees' measured IQs. Entry into supported employment had a more consistent impact on wage rates than on hours of employment. Individual placement was shown to have the largest effect on wages, while participation in mobile crews had little effect.
