I don't know a lot about home school.

But there are several kids in our church are kept in home school by their parents in order to "avoid" bad effects from other kids in public school. When my daughter just came to this church, they were so mean to her. In class when teacher asked kids to color, one of them even grab cryon from my daughter's hand and did not let her do anything. I just thought maybe she did not like my daughter and I did not know she was in home school at that time. Then recnetly a friend in church talked with me about those several girls and told me they were very mean to her daughter too. In class, they didn't permit her daughter sitting near them.
But I am not quite sure that is the problem of home school. :)
