Gender-typical educational and occupational goals are an important precursor of educational gender segregation and unequal opportunities of men and women in the labour market. However, little is known about how gender-typical aspirations develop during childhood and adolescence. Drawing on identity and opportunity arguments from a developmental perspective, this paper attempts to fill this gap by examining whether and to what extent gender-typical aspirations change during adolescence and how track allocation in secondary school is related to the development of gendered occupational aspirations between the ages of 15 and 21. The analyses are based on the Swiss Longitudinal Survey of Children and Youth. They include an observation span of six years, during which respondents were surveyed at the ages of 15, 16, 18 and 21.The findings show that gender-typical occupational aspirations were most prevalent at the age of 15. Their level and development differed by upper-secondary school track and gender. Young men’s aspirations were considerably more gender-typical than those of young women. Aspirations became less gender-typical for women in baccalaureate school and in initial vocational education and training programmes with high academic requirements and, in particular, for young men who entered vocational education and training with low requirements. Overall, our results support the assumption that changes in gender-typical aspirations during adolescence are the result of an interplay between opportunity structures offered by the upper-secondary school track, identity and status considerations.
