"Being the Union President likely she hasn't taught in school in years.
Even then - teachers are not Degreed on all subjects.
You have Math, English, History, etc.
Then you have the specific Education 'Level' the teacher is Degreed for. Like Elementary K-3, 4-8 or Secondary (High School)."
My bachelors degree (music) was awarded in 1979, and I haven't taught school since 1981. The problem is easy...even for me.
That being said, I saw in a latter post she's a Dem, so the 'heck' with her.
