I haven't seen any studies on children who were raised with un-schooling and their success in the "real world".

If someone can point to a study showing that this method is NOT detrimental to future success, I may consider it a legitimate course of study. But my gut reaction is one of, "This is semi-neglectful."

Would you consider un-schooling your child from K-12? Really?? What if you are not highly educated and able to identify any "gaps"?

What of social issues, especially in the teen years?

Where are the testimonials of wholly un-schooled children who have made a success of themselves (able to self-sustain)?

This is interesting:
