The regular method of classifying pupils in grades separated by intervals of one year or a half-year each, requiring all pupils to do a certain amount of work in a given time, regardless of the wide difference of abilities is common in most school systems. But because of the fact that all children have not the same brain capacity, this system has proven to be entirely inadequate, and falls far short of adapting itself to the needs of individual pupils. While many do not wish to depart from the ironclad, lock-step system, at the same time it is agreed among school men that such a system as would establish shorter intervals between grades, so that individual pupils may be transferred from one grade to the next higher without omitting any part of the course, would eliminate the difficulty and make our graded schools more effective.
