Find a co op of homeschoolers. Ask to interview any of them (with parents permissionof course) go as young as 3rd grade. Ask what they are learning. What they like to do when they arent in school... ask how they get along with their siblings. Pick another kid do the same thing. You will find they are smart, respectful, approachable, thoughtful, caring, funny. etc. We have friends that she dropped out of school in tennesee when she was 13. She wanted to homeschool their daughter. Daughter was given free ride to a top west coast school, double majored in business and finance. Was recruited in her Junior year to work at Deloit. Now 5 years later is earning 250,000K all from this mom that dropped out of school in 8th grade. Dont pick the person that is the worst at something to define a movement.
And that isn't even a handicap because the parents can learn as they go.
I did graduate from public school and public college, and I learned more by doing the homeschooling of my kids than any public education taught me.
So the claim that the parents must be educated doesn't hold water because it doesn't allow for the fact that the parents can and will learn too.
