I have the unpopular idea that Math, and in a broad sense, STEM, is mandatory for EVERYONE, especially teachers, regardless what they teach. Can a teacher teach well if his language skill is poor? Probably not, same for STEM.
Of course how much mandatory Math needed and IF a previous test has been passed is good enough is up to debate.
