By taking a child out of school you are, effectively, removing him or her from the education system for the rest of life, with all that that implies. Even if you are a qualified teacher you will not be able to give the in-depth teaching needed in secondary education. The education system may not be perfect but must surely be better than leaving a child at the mercy of one or two opinionated and, perhaps, neurotic parents who are convinced that they know best and, almost invariably, don't - and who will simply be instilling their prejudices into their offspring without giving them the opportunity to form a balanced view, based on their own experiences.

Being part of the education system gives children a far broader, more varied and certainly more balanced education than they can possible ever hope to achieve at home, exposing them to views and activities away from the narrow spectrum of their parents.
