In many Western countries, a considerable number of parents have removed their children from school and are teaching them at home. Such children do all their normal lessons at home, often under the guidance of a parent. The first thing to consider is whether this is legal or not. In most countries it is, so long as parents can prove that their children are receiving an adequate education, equal to that provided by their state educational system. The next consideration is whether the parents have the time, self-discipline, intelligence and patience to teach their own child week after week, day in and day out, for hours on end. Then there is the problem of what will be taught, and how.
