An Empirical Classification of Occupations Based on Job Analysis Data: Development and Applications.
Gottfredson, Gary D.
This paper briefly describes the development of a comprehensive dictionary of Holland occupational codes and other information for each of the 12,099 occupations defined in the government publication "Dictionary of Occupational Titles" (DOT). This classification was created by using 189 occupations with firmly established Holland classifications. Job analysis data from these construction-sample occupations were used together with multiple discriminant analysis to develop equations estimating the probability that an occupation belongs to one of the six Holland groups. These equations were successful in classifying 88 percent of the construction-sample occupations to the Holland category to which they belong. The comprehensive classification provides extensive coverage of moderate and low level occupations, and makes available extensive listings of Holland codes for occupations requiring little education, making it possible to apply the classification and Holland's theory in vocational assistance for poorly educated or hard-to-employ populations. A series of figures is included which shows the percentage and number of occupational titles in different categories of the classification; the percentage of low level occupations by classification; the mix of employment for men and women in 1960, 1970, and 1980, by classification, and the percentage of men and women employed in 1970 and 1980 in each classification requiring college preparation. The appendix shows employment and learning data for 503 occupations grouped by Holland category and level. (NRB)
