Research examined the relative desirability of categories of information supplied by a keysort search procedure, as judged by users. The Career Information System was used as the framework for obtaining occupational information organized around the concept of the Worker Trait Group (WTG). Four groups of students in each of grades 9 through 12 identified occupations based upon the following four pairs of binary personal preference variables: 1) vocational interest; 2) preference for data, people, or things; 3) interest factors; and 4) temperament. Keysort cards, each representing a WTG, were obtained, randomized, and classified by the students as preferred, acceptable, or unacceptable. Results indicated that only the vocational interest variable led to the selection of preferred WTG's. It was hypothesized that this was partially due to the fact that the instrument used to obtain scores for this variable, the Ohio Vocational Interest Survey, was superior to those used to obtain the other variable scores, which were open to student misinterpretation. Additional research was recommended to determine if revision of these instruments or the means of administering them would produce variable scores leading to the retrieval of more desirable information.
