"Do most homeschool parents have the necessary skills to teach some of the more difficult courses? What about languages, which are often required for entrance to college?"
Not all do, which is why they hire me, I teach advanced math. I know a couple of people who offer both Latin and French clases, as well as kids who take courses at the local community college.
However, most homeschooling parents are college educated themselves, and just teach the language they learned such as Spanish or French.
Is this an actual statistic?
I applaud parents who are this involved with their children!!! I wonder if this kind of parental involvement with publically-educated students might help to correct the sway toward which the system might be heading.
Too often public school teachers hear the likes of, "I take care of them at home, you take care of them at school. Don't bother me with your part of it."
Parental involvement is essential in any good education!
