The Office of Basic Education Commission (Obec) has decided to let each school decide whether they should reopen on July 1 or use distance-learning television (DLTV) and online learning.

"There are schools in urban, rural and remote areas. Since we believe one size doesn't fit all, we have decided to let each school make its own decision, with students' safety as the bottom line," said Obec secretary-general Amnat Wichayanuwat.

Mr Amnat said that schools wishing to open must first get permission from their provincial governors.

"If the risk of Covid-19 is very low in their area, normal classes may be possible," he said, adding that education officials would assess risks before the new semester.

"For instance, if the virus still poses a risk, we may arrange for students to take turns attending school. If there are 30 students per room, only 10 may be allowed to attend class at a time, while those at home can work on assignments," he said.

Moreover, the schools will have to screen body temperatures and clean frequently, adding that teachers and students will also have to strictly follow the ministry's guidelines such as wearing masks and washing their hands.
