What is the ruling on guarding music exams scheduled by the Ministry of Education?

It is not permissible for a Muslim to invigilate music exams or work in them, for that entails an affirmation of forbidden music and cooperation in sin and transgression. Allah Almighty said: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." There is no difference in this regard between what is decreed by the Ministry of Education or any other entity.
