The area of performance appraisal of the handicapped individual is a relatively uncharted domain. Previous studies have tended to either lump categories of handicaps together or to concentrate their performance appraisal on simplistic performance criteria. This dissertation focused upon the performance of a group of physically impaired workers and their non-impaired co-workers. Central to this research endeavor was a comparison of the aggregate performances of both groups of workers through the use of parametric factor and discriminant techniques as well as the non-parametric sign test.
