There are right and wrong ways to home school. We have our teenage granddaughter in a home school support system that is a vast improvement over the local public schools. The program is modeled on some very progressive systems in places like Finland. They are grouped by ability rather than age and very strongly encouraged to take responsibility for their own learning. In the time we've been involved with the school (six or seven years I think) all but one of the graduates has been accepted at every college they applied to. That one student had to settle for her second choice.
There are some good programs out there, don't tar all of them with the same brush.
