I estimate the higher education access gap among individuals who study in different type of upper secondary school. I use a non linear Binder-Oaxaca decomposition as de-pendent variable is a binary choice. The sample data is a household data that pull out from three waves of Indonesia Family Life Survey (IFLS). The results show that student from public school has higher chances to attend post secondary education as compared to private Islam and private secular group, whereas, private Christian is superior than pub-lic school. The evidence also indicates there are considerable differences between public school, private non-religious and Islamic school graduates in academic achievement and socio-economic characteristics. Parents’ education and academic achievement provides important contribution to a low probability of entering higher education for private non religious school graduates. While father’s education and family income contribute sub-stantially to a low probability of accessing higher education for the private non religious group.
