The paper asks how cantonal education systems in Switzerland promote gender-typed  school-to-work transitions and gender segregation at work. Data from the Swiss TREE  youth panel study is used to analyse the impact of cantonal provision of vocational educa- tion and training (VET) on gender-typical educational trajectories. The findings show that  education systems with higher VET rates have higher allocations of men in gender-(male-)  typical occupational careers. The paper concludes that the pronounced and persistent  gender segregation on the Swiss labor market is partly due to a prominent VET system,  which urges early gender-typed occupational career decisions.
