Despite adolescent girls' superior school achievement and high career aspirations, fewer women than men achieve career eminence. Understanding early influences on the development of gifted girls' career-related values and aspirations may help to explain this discrepancy in career outcomes. This article reports findings from a qualitative, cross-sectional study of influences on career development for 18 girls in eighth, 10th, and 12th grades in selective entry high school programs in three Australian schools. Data from two rounds of interviews were analyzed thematically in relation to the career development theories of Gottfredson and Savickas. Findings highlighted the interrelated influence on career values, goals, and choices of (a) perceived personal traits, strengths, and interests, and (b) relationships and experiences grounded in home, school, and community contexts. Key findings are discussed for research and educational practice related to supporting career development in gifted girls.
