In the past two decades, significant advances have been made in understanding the vocational potential of severely physically impaired adults. However, instruments to evaluate the vocational ability of these persons have been scarce or unsuitable, and attempts to adapt existing instruments or to develop new methods of evaluating these persons have been fragmentary. In this report, a researcher from England, unfettered by the constraints of particular United States schools of thought, summarizes current thinking in the field of vocational evaluation of severely physically handicapped adults. The report summarizes traditional do's and don'ts that will be helpful to the beginning rehabilitation professional, while also including complex procedures which are new or those which vocational evaluators have tended not to adopt because of their complexity. Topics covered in the publication include (1) types of vocational evaluation, including pre-vocational evaluation, prescriptive evaluation, and predictive evaluation; (2) modifications to vocational evaluation tools, including discussion of psychometric tests, work samples and manual dexterity tests, and situational assessment and job tryouts; and (3) special techniques such as rehabilitation engineering, use of micro-motor analysis to establish motion times, and the Available Motions Inventory. A bibliography is included in the report. (KC)
