The Centre for Covid-19 Situation Administration (CCSA) is considering allowing schools in infection-free areas to reopen first in July.
The proposal has been forwarded to Prime Minister Prayut Chan-o-cha for a decision, Education Minister Nataphol Teepsuwan said on Wednesday.
His ministry is conducting inspections to find out whether schools can reopen.
They must prove measures to prevent a new Covid-19 outbreak can be used. Schools are listed among places with the highest risk of disease transmission.
Meanwhile, the government is preparing to send out two million TV signal receivers to fix glitches in its distance learning television (DLTV) broadcasts since Monday.
Many children, mostly in remote villages, have been unable to view the content, which is part of a state plan to hold virtual classrooms in case the Covid-19 situation is still volatile.
The ministry has set July 1 as the start of 2020 academic year but may change this if mass gatherings of students, teachers and parents when schools reopen are considered too risky.
Students must be able to study at home, but "we have found most cannot tune in to DLTV programmes," Office of Basic Education Commission (Obec) secretary-general Amnat Wichayanuwat said.
"There are also some mistakes in DLTV content, but we are looking into it," Mr Amnat said.
