Yeah, but Ironwood is simultaneously a General in the Atlesian Army and the headmaster of the Kingdom's Upper Level Hunting Academy. So he is at the very least qualified to oversee hunters training.

Also, I don't know how it is in the USA, but in Argentina, most headmasters have been teachers before being made headmasters (it is an unnoficial requirement).

So if Ironwood is qualified to execute work in both areas, I do not see why Glynda wouldn't. Particularly since Glynda seems to teach the class where students fight with each other rather than against Grimm.
