The Office of the Basic Education Commission (Obec) is standing by its plan to merge some small schools nationwide and says it will move students in these schools to bigger ones.
Obec secretary-general Chinnapat Bhumirat said he had asked all educational zone directors to work out a plan to move students from schools with less than 120 pupils to study at larger ones.
Mr Chinnapat said the directors must conduct a survey on how many small schools in their areas could be merged.
He said the merger is necessary to improve the quality of education at smaller schools.
Schools with fewer than 120 students were suffering due to a shortage of teachers and learning tools.
He said students from some small schools should be moved to study at bigger schools which boast experienced teachers and better instructional materials.
"But not all small schools will have to be merged and not all students will have to be transferred," he said.
