The Relationship between High School Sector and Educational Success: Focusing on the Social Background of Private High School Students

Abstract

This study investigates the influence of high school sector on educational success in Japan. A range of previous research on disparities among high schools has revealed that high school rank (based on the academic ability of pupils, etc.) originated from the democratization of high school. However, given that the democratization of high school is supported by private high schools, high school sector may become a factor for high school ranking. The data used for the analysis are the 2005 National Survey of Social Stratification and Social Mobility (SSM) in Japan. The results indicate that students who enter private high schools have lower academic ability than students who enter public high schools. By contrast, private high school students have greater educational success than public high school students. Moreover, this study reveals that private high school students are generally from a higher social class than public high school students. Given that the use of entrance examinations for private junior high schools has been increasing since the 1990s, in the future, the effect of private schools on educational success may become stronger in not only high schools but also junior high schools. This study thus emphasizes the importance of paying greater attention to the relationship between educational success and the private and public school sectors.
