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.

高中部门与教育成功的关系：关注民办高中生的社会背景

本研究调查了高中部门对日本教育成功的影响。此前一系列关于高中差异的研究表明，高中排名（基于学生的学习能力等）源于高中的民主化。然而，鉴于高中民主化得到私立高中的支持，高中部门可能会成为高中排名的一个因素。用于分析的数据是日本 2005 年全国社会分层和社会流动性调查 (SSM)。结果表明，进入私立高中的学生的学习能力低于进入公立高中的学生。相比之下，私立高中学生的教育成功率高于公立高中学生。而且，这项研究表明，私立高中学生的社会阶层普遍高于公立高中学生。鉴于自 1990 年代以来私立初中入学考试的使用一直在增加，未来私立学校对教育成功的影响可能不仅在高中而且在初中也会变得更强。因此，本研究强调了更加关注教育成功与私立和公立学校部门之间关系的重要性。私立学校对教育成功的影响不仅在高中而且在初中可能会变得更强。因此，本研究强调了更加关注教育成功与私立和公立学校部门之间关系的重要性。私立学校对教育成功的影响不仅在高中而且在初中可能会变得更强。因此，本研究强调了更加关注教育成功与私立和公立学校部门之间关系的重要性。
