Who gets to decide which parents are qualified to teach? You? The government? What if a parent can competently teach every subject but insists on "brainwashing" their kid with Bible stories and moral lessons?
I was homeschooled from day one, mostly by my high school graduate mother. I'm studying computer science in graduate school now. Someday I'm going to teach my own kids. I think I'm qualified and you'd probably agree - but what about some government minion who thinks I should teach my kids about the joys of "diversity"?
Hug your mom! She obviously was a wonderful teacher, and you are living proof of her efforts. You'll be a wonderful mother and teacher. Apples DO fall near the tree. :)
