Every kid I knew that was home-schooled fared badly. For most it was just an excuse for lonely moms to keep kids around, for kids to somehow count field service and indoctrination as their school work, and to avoid any worldly association. Many didn't graduate and got a GED at best. They learned that education isn't valuable. I remember looking at the books my sister had as she graduated from Penn Foster's home program and thinking that it was on par with what I did in middle school. I'm glad I got to go through "traditional" programs and wish I had gone to college. From every experience I've seen, home schooling is a joke.
Most lacked social skills too. It isn't just the actual book learning that suffers.
In our area of the United States (Indiana/Kentucky) more and more were turning to home schooling when we left.
