In this article, we examine social origin differences in employment patterns across different stages of higher education and compare these differences between vocational and academic fields of study. Using data from a large-scale German student survey, we study the development of inequality, according to social origins, in student employment from first-year to graduating students. We show that inequality in job quality exists and is partly attributable to the need for students from lower social origins to work in order to finance their studies. We hypothesise that initial inequalities decrease as students progress through higher education. While we find evidence for this hypothesis, we also show in multivariate models that the reduction of inequality in the student labour market is explained by prior differences between social origin groups.
