By 1992, Vahey and his wife moved to the prestigious Jakarta International School in Indonesia, where he again taught social studies, coached basketball and developed a reputation for leading fun overnight trips for students.
When Obama attended school in Jakarta in the 60s and 70s, it wasn't this one.
He attended a couple of local schools.
Obama attended the Indonesian-language Santo Fransiskus Asisi (St. Francis of Assisi) Catholic School around the corner from their house for 1st, 2nd, and part of 3rd grade. ... From January 1970 to August 1972, Obama's mother taught English and was a department head and a director of the Institute of Management Education and Development. Obama attended the Indonesian-language government-run Besuki School, one and half miles east in the exclusive Menteng administrative village, for part of 3rd grade and for 4th grade.
