Minnesota Occupational Classification System (MOCS III) 1987: A Psychological Taxonomy of Work
(Note:This PDF document is approximately 64 MB)

This volume presents a classification system that is the product of thirty years of research by the Work Adjustment Project. MOCS III classifies 846 benchmark occupations and 923 alternative occupational titles in the form of 131 separate taxons. Occupational membership in a given taxon is determined by status of the occupation on two dimensions: ability requirements and reinforcer system.The system is capable of classifying all of the occupations in the U. S. Department of Labor Dictionary of Occupational Titles. Additional information imbedded in the taxonomy is designed to enrich the amount of desirable and relevant occupational information available to the vocational counselor and the client.
