The different roles of public and private schools across the region and resulting educational disparities
Independent research project
Funding: JSPS KAKENHI Grant Number 21K13315
Overview:
Regional and temporal variation in private high school tuition reductions in Japan is exploited.
Attention is directed to regional differences in the academic balance between public and private schools.
In regions where private high schools are academically stronger than public schools, lower tuition is linked to improved middle school performance.
