The students are taking part in a controversial experiment to get the day off to a much earlier start.
The pilot project in Kupang, the capital of East Nusa Tenggara province, has twelfth-graders at 10 high schools starting classes at 5:30am.
Authorities say the scheme, announced last month by Governor Viktor Laiskodat, is intended to strengthen children’s discipline. According to parents, though, children are exhausted by the time they get home. Schools in Indonesia generally start between 7 and 8am.
