Statistics show that home schoolers do as well or sometimes better than others in college testing, and so forth. I myself am not for home schooling, I think it puts kids at a social disadvantage, but that can have an upside too. What I didn't realize, well in this area anyway, is that if a child is home schooled, he can participate in some activities in his school district. When my daughter was in high school, there was a home schooled JW (I knew the family from back in the day when I was in) and he was in the high school band with my daughter. They were really good friends, although his mother didn't like it when she found out I was an inactive JW! Anyway, when he turned 18, he moved out and came out as gay. He is still good Facebook friends with my daughter, he has moved away, I think to get away from his mother, HA!( By the way, I never did understand how a JW could be in the school band, playing the alma mater, national athem, and holiday programs. Dont know why I never asked him that.)
I think the big problem with JW home schooling is that they would not get as rounded and as an inclusive education of all theories, science, etc, that "normal" home schooled kids would get. I am sure JW parents would exclude a lot from the curriculum, as well as promote some things that are just not correct. Can you imagine, for some JW kids, contact with school mates is the only normal interaction they have, and if that is taken away, imagine how unprepared for anything they will be.
