A procedure for using the interest scores of occupational group members to locate (map) occupations on Holland's (1969, 1971) hexagon is described. The procedure locates occupations throughout the hexagon--not just at six points. Score profiles for Holland's six types were obtained from administration of the Unisex Edition of the ACT Interest Inventory (UNIACT) approximately 8 years prior to determining the occupations of 3,612 four-year college alumni. The hexagon locations of 51 occupations pursued by these alumni were determined through the application of hexagon-based weights to their score profiles. The weights convert the profiles to scores on the data/ideas (D/I) and things/people (T/P) work task dimensions that underlie Holland's hexagon. Several applications of hexagon locations are described, including a Hexagon Congruence Index (HCI) that reports person-occupation and other congruence on a scale anchored to the hexagon. The HCI can be used with six-score profiles of Holland's types, three-letter codes, two-letter codes, high-point codes, or any combination of these reporting procedures. (Appendixes include a description of procedures used to analyze statistical significance of occupational differences; UNIACT, D/I, and T/P mean scores for 51 occupational groups; six-score profiles for selected occupational groups; and occupations most congruent with each Holland type, as determined by the HCI. There are 35 references. (Author/KC)
