This document supplements ED 025 264, a study of 2,459 individuals enrolled in one of 43 occupation-centered curricula in 20 California junior colleges. The parent study compared students' questionnaire responses about home and educational backgrounds, and about attitudes presumably related to both vocational choice and choice of curricula leading to the selected occupations. In this supplement, the relationships between responses to selected questionnaire items and scores on the Interest Assessment Scales (IAS) and Omnibus Personality Inventory (OPI) are the primary concern. These relationships are displayed in 30 tables and show that: (1) a widespread difference in age exists among students in various curricula; (2) the IAS was more effective than the School and College Ability Test in classifying subjects according to their choice of curriculum; (3) IAS and OPI correctly classified the following percentages of students according to: perceived high school achievement (IAS-28 per cent, OPI-30 per cent); job risk preference (IAS-40 per cent, OPI-44 per cent); and highest source of life satisfaction (IAS-18 per cent, OPI-24 per cent); and (4) a comparison of IAS and OPI scores of currently enrolled students and graduates who take jobs closely related to their junior college training indicates that the two groups are similar in interest scores.
