This is the first insight into effect of development of nonpublic and paid schools on social stratification in Poland. Logistic and multinomial regression of the Polish general Social Survey data 1998 is conducted to test hypotheses concerning effect of the fathers’s EGP category on access to various types of schools in secondary and tertiary education. Results confirm the hypotheses that respondents from intelligentsia families are overrepresented in both secondary and tertiary paid schools and have greater odds of entry in to public tertiary education in comparison to lower non-manual categories, owners, working class and peasants. Children of intelligentsia also have more opportunities to attend “better” stationary (than non-stationary) schools in comparison to other categories. This analysis provides support for the thesis about growing role of qualitative differentiation in education.
