In Middle Ages, as in  my country China , home schooling was quite common. The majority found their children a private teacher in preparation for national capacity screening(like SAT in the US) slash civil servants election. Seems one went through the entire education all at home, meaning he/she pursued political ascendency. Now it's rare from the microwave of media, because China has made it a compulsory right for children to go to school. By the way, being at home is also OK.
