The history of American education shows that the schools have always responded to demands for adjustment of education to the needs of the community. At the time when the high schools came into existence the need was for leaders of society, i.e., doctors, ministers, and scholars. Accordingly, the major function of the high-school teacher was to train pupils for leadership. The curriculum was designed to prepare them for college. Entrance was made intentionally difficult by examinations designed to exclude those not qualified. This made the high-school population a rather select group of pupils. It is interesting to observe that mathematics was a major subject which everybody was required to take.
