The main purpose of this research was to investigate the phenomenon of shadow education in Greece. In this research, the quantitative research method is combined with the qualitative method. The results showed that the liberalization of education during the recent decades was accurately implemented in the institution of shadow education. Knowledge is becoming a commercialized product and the choice for private education is made through private-financial criteria. Restrictive and maladjusted educational policies and decisions relating to individuals' needs support the development of this institution, highlight the exchange value of academic credentials of the individual, and exacerbate social inequalities.
