I know a few families that do homeschool, or have homeschooled their kids. It seems to be working out pretty good for them. In being around their kids I’d say they’re sharp and really well mannered. I think the moms did most of the schooling.
I’ve talked with a few adults that were homeschooled as kids over the past few years. Seemed to me the common theme was: the schedule they had was awesome (usually by noon or early afternoon they were out playing/having fun), the school work was more advanced, and they just seem to be pretty sharp people. One ended up transferring to public school in 8th grade, mainly for sports i think, she said the school work in school was easy. She actually ended up playing sports in college. I personally haven't recognized any awkward social skills, but I’m not around them enough to have a strong opinion on that.
