Seven commercially available work evaluation systems are compared using a standardized outline: development, organization, work evaluation process, administration, scoring and norms, observation of clients, reporting utility, training in the system, technical considerations, reviewer's summary and comments, address, cost, and references. There are four sections: (1) a brief paper listing factors to be considered in selecting a commercial evaluation battery for such tools as on-the-job evaluations, sheltered employment, work samples, and psychological tests for assessing clients' potential; (2) an explanation of the fourteen major points (criteria) in tne outline; (3) a table presenting brief comparison of the seven systems on the first ten points (points 11-14 not appropriate to summarized; and (4) more detailed description of each system including reviewer's comments, address, cost, and references. The seven systems covered are McCarron-Dial Work Evaluation System, Philadelphia Jewish Employment and Vocational Service (JEVS), Singer Vocational Evaluation System, Talent Assessment Programs (TAP), The Tower System, Valpar Component Work Sample Series, and Wide Range Employment Sample Test (WREST). Four more recently developed systems are compared in a separate document (see Note). (JT)
