The main idea of the article is to show the importance of education as a factor in identifying the middle class. This means that people with middle class status are involved in various structures of society and they have reached prestigious positions respectively which, in turn, affect the extent of their inclusion in society. Middle-class representatives have complete and successful career realization, and they are signifiantly more inflential from a social point of view in comparison to other individuals which are less integrated and less successful following the public indicators of personal success: education, income, prestige and political power. The paper is primarily based on results obtained through the European Social Survey (ESS) under the 2006, 2009 and 2013 waves. Findings of the present paper are that quality education is not only a function of effort, ambition and persistence, but also of parental involvement, culture capital and family background. Educational achievements are a stimulus for middle-class expansion because they present investment in social contacts and competition on the labour market.
