He said the semester start could be postponed further if the inundation persists.
Woravat said the massive flooding had caused huge losses and that about Bt1.4 billion was needed to repair these schools. The ministry will ask the Cabinet to allocate the funds.
Schools where the floods have receded can start repairs and seek reimbursement later, he advised.
Meanwhile, more than 100 schools in flooded areas are providing shelter to evacuees, while some schools have set up kitchens to provide meals to those affected.
Woravat has urged people who need assistance to call the 24-hour 1579 hotline or contact schools nearby.
