A study explored the agreement in occupational fields between adolescents' career aspirations and career expectations and the influence of gender, grade, and locus of control on this agreement. The reasons for occupational choice were also examined. Subjects were 500 randomly selected 8th through 12th grade students attending a secondary school in the lower mainland of British Columbia, Canada. Instruments were an open-ended questionnaire regarding career aspirations and expectations, a scale to estimate probability of obtaining ideal and real occupational choices, and measures of reasons for career choices and locus of control. Results supported the research hypotheses and indicated that little agreement in occupational fields existed between career aspiration and expectation and that there was no grade, gender, or locus of control influence. Similarly, no differences between the reasons for ideal and real occupational choices existed. It was found that reasons for occupational choices varied across grades. (Appendixes provide the instruments and tables of summaries of reasons given by students for ideal and real occupational choices.) (YLB)
