Predicting vocational aptitude of mentally retarded persons: a comparison of assessment systems

The relationship between the AAMD Adaptive Behavior Scale (ABS), the Behavioral Characteristics Progression Scale, and the McCarron-Dial Work Evaluation System and the vocational competencies of mentally retarded clients, as typically assessed by the San Francisco Vocational Competency Scale, was examined. Results were discussed in terms of the general applicability of the McCarron-Dial Work Evaluation System in assessing vocational potential of retarded persons when compared to either the ABS or the Behavioral Characteristics Progression Scale.
