The Vocational Education Commission (VEC) has begun an investigation into accusations that a teacher at Roi Et Technical College gave every student in his class an F in a test and demanded money to change it.
A student claimed in a post on social media that the teacher failed everyone on Wednesday and demanded 400 baht to fix it. However, the price was later reduced to 200 baht, the post said.
The post said everyone ended up paying 200 baht each and uploaded pictures of transaction receipts.
It claimed that the teacher gave As and Bs to students who paid in previous tests.
Yotphon Wenukoset, VEC secretary-general, said a fact-finding panel was formed after it received information from the college about the allegation against the teacher on Thursday.
Regarding administrative measures, the VEC has cancelled a course supervised by the accused and consulted with relevant officials, including a deputy director, department head and adviser at the college, to seek solutions, he said.
Students in the class were questioned over the matter, he said.
He said the VEC had instructed officials to finish the probe in seven days.
