The Ministry of Education and Training has decided that ceremonies to launch a new academic year will take place on September 5 across the country.
It said schools are strictly forbidden to hold classes before this date.
The ministry is also planning to reduce the curriculum of the 2020-2021 school year to 35 weeks for all levels of education in order to increase the time for extracurricular activities and summer breaks.
As of June 30, about 888,000 high-school seniors had registered to sit graduation examinations scheduled for early August, of which 636,000 will use their results from the exams to apply for university and college positions.
