Education Minister Natthapol Teepsuwan said he gave the order on Tuesday to cancel the tests for students in Grade 6 and Grade 9.
The decision to suspend the exams would also reduce anxiety among students, said the order.
Natthapol added that the ministry was also planning to upgrade school curriculums to cater to differences in schools and students’ interests across the country. The O-NET would be changed in future to reflect this more localised approach to education, he said.
