We have homeschooled our seven children. I have a doctorate, but not in anything you are likely to think certifies me as a teacher. Neither my wife or I are “credentialed” in the government's or NEA’ opinion, but we are credentialed by the One who led us to home school and has blessed our children (three grown and away from home; two married -— ALL serving the Lord) with uncountable blessings.
Correct principles trump credentials any day of the school year.
I seriously considered getting a teaching credential until I looked over the curriculum requirements. Forget it. I could get through it, but who would want to?
I'm getting my masters, and the public schools will have to do without me.
