Few studies have identified individual differences in vocational knowledge or its association with career aspirations or expectations of children. We investigated whether individual differences in grade, gender, academic achievement, and SES predict levels of vocational knowledge, and further examined the relationship between vocational knowledge and career aspirations and expectations. Children in the fourth through seventh grades (N = 132) from two rural school districts were administered measures of vocational knowledge, expectations, and aspirations. The results of this study suggest no differences in vocational knowledge in groups differing in grade, gender, and SES; however, academic achievement was a significant predictor of vocational knowledge. Moreover, results of regression analysis demonstrated that vocational knowledge adds significantly to the prediction of career aspirations and expectations. These results contribute to the emerging literature exploring mechanisms involved in the career development of rural children. (Contains 3 tables.)
