The study examines the relationship between social inequalities (stratificational, gender and other disparities) and schooling, including academic attainment, longitudinally, in Slovenia. The issue is indicated most clearly at the tertiary education level. The basic finding is the parallel between educational expansion and the diminution of social inequalities as measured by standard parameters. This was particularly evident in the 1990s. Inequalities are measured in terms of gender, parental education and occupation. The impact of parental education proves to be an indicative, observable and longitudinally comparative measure. Parental occupational status is also clearly linked to their children’s scholastic attainment, although there are difficulties in the formation of occupational strata. Further considered is the impact of school reforms over a lengthier period of time; there was not, however, any detectable impact. School and welfare policies, even financing, have little significance. There are clear indications that social disparities at school are continually regenerated, despite the decline established by standard measures. New forms of social disparities appear, through which the privileged ensure the continuation of privilege.
