And it’s working! I got a credential through a program that took people from math and science jobs and gave us a fast track to a credential. Of the 3 engineers in the program, all of us quit teaching in the first year. We were disgusted at how education had deteriorated.
Anyone capable of doing something else eventually quits what passes for teaching these days.
Did you try a private school? I recall something about private schools being more interested in subject matter expertise than ed-school credentials, but my info may be way out of date.
