“ If the teacher really teaches, and faithfully watches the mental growth of her pupils through the work of one or more years, she alone is the best judge of their fitness to do the work of the next grade. The examinations of a superintendent should be to ascertain whether the principals under his charge have the requisite ability and knowledge to organize, teach, and supervise a large school. The examinations of the principal should test the teaching power of his teachers. And, lastly, the teachers should test by examinations the mental growth of their pupils. ”
