In response to criticisms of the sex bias/fairness of career inventories, new guidelines, modifications to existing inventories, and new inventories have been developed. The occupational card sort, Occu-Sort (O-S), was administered to junior and senior high school students from suburban and urban communities to assess its effectiveness in broadening the career options of female students, and also to evaluate the reliability of the three-letter occupational code obtained from the O-S. To avoid sex bias, the same set of cards was used by both sexes. Neuter forms of occupational titles were used and occupations with strong sex-role associations were avoided. Groups using the Self-Directed Search (SDS) and a no-treatment group served as a control. Results revealed that use of the O-S suggested a greater proportion of nontraditional jobs to female students when compared with the SDS; male students were unaffected. There was no difference between O-S and SDS students in ability to recall the three-letter code. The O-S letter occupation codes were moderately stable over time and provided moderately positive evidence for the construct validity of the codes. (The appendices provide an O-S lesson plan, an SDS teacher guide, student opinion forms, and three vocational guidance questionnaires.) (MCF)
