How School Climate Affects Student Performance: A Fuzzy Set Qualitative Comparative Analysis Based on the Perspective of Education System

School climate’s dynamic effect on student is widely explored in the study in different subjects; however, quietly, a few types of research concentrate on comparing different dimensions of school climate’s effect on student and the influence path in different countries. To analyze and compare the school climate’s mechanism in different countries’ basic education system, this article used a comparative method to explore the explanation of school climate on school students’ performance. With the application of 73 countries’ panel data from the PISA database, the author calculated the different school climate combinations’ consistency and coverage in relation to school students’ performance by fs-QCA. The author found that the punctuality of students and the classroom discipline can explain the good performance of students. It also found that the combination of multidimensional school climate has a higher explanatory power than a single factor. Finally, this study ends with countermeasures and suggestions which include improving the school climate of the regional education system and improving the utility of school climate through the appropriate mix of school climate.
