Career exploration is a developmental stage identified by career development theorists and occurs typically during adolescents when boys and girls try out various work roles in part time work, volunteer work, or in school/community activities. This digest focuses on gender differences in the role of assessment in the exploration process. Girls have been found typically to explore careers from a narrower set of career options than do boys. This occurs based on occupational sex role socialization. Career education programs and classes in high school have attempted to reduce stereotyping in a variety of ways. The most frequently used measures to aid in career exploration during adolescence are career interest inventories. The National Institute of Education Guidelines for reducing sex bias in interest measurement were followed to a large extent by both interest measurement test developers and publishers in the decade following their publication. However, the continuing evidence that gender differences exist in career interest measurement strongly suggests that such assessment is accompanied with counseling. (JBJ)
