I very rarely post on these types of threads, but I have been reading this one with interest and just want to give a slightly different view than those on here already.
I home educate 3 children. None have been to school. None have special needs or any bad experience with the "system" that led me to home educate them. I have no axe to grind with schools, those who send their children to school, or any group that educates their children in a way different than I do mine. I chose home education because I felt it offered my children the best possible opportunities and future - the same reason, I am sure, that all parents choose their way forwards.
My eldest is about to enter school for the first time this September at age 16. A 6th form college to do his A levels. He has completed 7 GCSE's as a private candidate. We have the results for all except one (French which we will get this coming Thursday). He has: Maths A, Further Maths A (it does not go up to A and in fact he achieved 92 out of 100), English A, English Lit B, Physics A, Computer Science A*, and we fully expect an A in French next week. He was not tutored or taught any of these subjects. As with all my children, I have facilitated their education, providing them with the right resources and environment but they have taken control of their own learning.
All my children are extremely social and involved in large numbers of clubs and activities both within the home ed community, and as they have got older, outside of that community. Just like schooled children, they have many interests outside of their school work and actively pursue them.
I am not on here to brag about how well my son has done, but to show you another side. There are many families like mine that home educate successfully by choice, not because our children were failed by the system, or because we are "hippies" that want to turn our backs on formal education. We are the unseen/low profile families though. As with all areas of education, and life in fact, there are success stories and failures and lots in between. Home education does not work for all families - I have seen some spectacular failures over the years. But school does not work for all families either. There is no one size fits all approach in life.
