Privatization of education has expanded dramatically worldwide in the last two decades, and Turkey is no exception. It is seen that the developments affecting the transformation of public services began with the implementation of neoliberal education policies, especially after the 1980s. These policies have led to a significant transformation in the field of education. After this period, the field of education, which was offered as a public service, began to be increasingly privatized. This process, which causes significant effects in all areas of education, shows that the privatization of education also has a significant impact on school choice processes. The main problem of this research is to try to understand the appearance of the segregations in education that arise due to school choice processes and the possible effects of educational segregations. Therefore, this research aims to focus on school choices, educational segregation, and the possible effects of this process during the privatization of education in Turkey. As a result of the research, it was revealed that exam scores and the distance from the school to home were the most determining factors in school choice for students studying in public high schools. Therefore, it can be said that there is a compulsory school choice process for students studying in public high schools. It is seen that students and parents studying in private high schools choose qualified private schools with high academic success due to the aim of accessing a qualified education. Parents' view of education as an investment and deficiencies in public education are other important factors in choosing a private school. Among the important results revealed by this research study is that school choice leads to students accessing schools of different qualities, deepening educational disparities depending on class position and educational inequalities.
