I could swear this was asked here before (years ago) but I can’t find it at all.
The story is about a man who is preparing to take a test. The narration is about how proud he was when he became a school principal and how much more he can do for the children and society if he passes this test, so you’re led to believe he’s testing to become some sort of superintendent or board of education member. At the end, it’s revealed that he’s testing to become a teacher.
I say this may be a science fiction story because it’s pretty counterfactual and because at the time I read it (30-some years ago) I was mostly reading sci-fi and fantasy.
