My cong. has probably 15 kids up to age 12 or so. One by one they started homeschooling and now they are ALL HOMESCHOOLED. They are all barely literate and are very, very unintelligent. It's quite sad to see the squandered potential. I imagine home schooling is pretty easy to a point, but what do you do when they start getting into advanced math or sciences? You're fucked. You can't teach them. All you can do is rely on the book.
I know ONE person my age who is a home school success. Super smart, near perfect SAT scores, got a college scholarship and took up engineering. Of course he decided to move to South America somewhere and pioneer, but that's besides the point. The only reason he did well is because mom is a retired college professor so she was actually qualified to teach. That's obviously an exception, so he got lucky.
