The Extension of Holland's Occupational Classification to All Occupations in the Dictionary of Occupational Titles.
Viernstein, Mary Cowan
Two methods are presented for extending Holland's occupational classification to include all occupations in the Dictionary of Occupational Titles (DOT). Holland's classification is based on a theory of personality types, with occupations in the classification organized into major categories (Realistic, Investigative, Artistic, Social, Enterprising, and Conventional) and subcategories using the same concepts. The two conversion methods enable translation from any DOT occupational code (a six digit number) into the corresponding Holland Occupational code. The first method is essentially an application of Bayesian statistics to 399 occupations in Holland's Occupational Classification, while the second method was developed by using the definitions of each DOT group (first three DOT digits) and assigning the Holland code which seems theoretically consistent with the DOT definition. Testing and comparisons with four occupational samples revealed that Holland's classification could be extended to all DOT occupations. (Author)
