Education Minister Ali Asghar Fani received his third official warning, known as "yellow card", from the parliament on Monday.
Fani reportedly failed to provide satisfactory responses to lawmakers' questions about the employment of incompetent personnel, the ministry's "disregard" for human resources and teachers' healthcare and salaries, IRNA reported.
Of the 169 lawmakers who voted in the session, 83 MPs said they were not satisfied with the minister's explanations, 78 were satisfied and eight abstained.
