(1) _Appearance._ It is the testimony of every superintendent and pastor who has graded his Sunday school that the appearance of the school is greatly improved by the graded system. The older scholars are assembled in one body, instead of being scattered throughout the room; scholars of the same size and age are brought together in classes. The school will also actually seem larger than it was before the grading. (2) _Order._ The order of the school will be more easily maintained. The big boys and the giggling girls, both at the self-conscious, awkward age, will be in a new environment, no longer the leaders over smaller and younger pupils, but in classes by themselves, and with responsibilities appealing to their self-respect. (3) _Social Relations._ It will be a benefit to the scholars of each age to be associated in groups of the same period in life, with the same interests and similar mental acquirements. Many scholars will find their new associations more congenial than their former ones in the ungraded classes, where older and younger people have been brought together. The class will now become, far more than it was before, a social power. (4) _Teaching Work._ In the ungraded class, with older and younger pupils together, the teacher met with his greatest difficulty in finding a common ground of interest. In the graded class, with pupils of uniform age and equal intellectual understanding, the teaching can be better adapted to the needs of the pupils. (5) _Incentive to Interest._ The prospect of promotion awakens an interest in the classes. Each scholar looks forward to the time when he will attain to a higher grade with its enlarged privileges. (6) _Obtaining Teachers._ The grading of the school greatly aids in the solution of the ever-present problem of obtaining new teachers, (a) The graded school requires a smaller number of teachers than the ungraded school, since it provides for the consolidation of skeleton classes in the Senior Department. This sets at liberty a number of experienced teachers for service in other grades. (b) Whenever a new class comes from the Primary Department, a teacher is already at hand in the Junior Department whose class at the same time has advanced to the Intermediate Department. The teacher goes year by year with his class until it leaves the department, and then he returns to a new class beginning the studies of the same department. (c) After the results of a teacher-training class are available there will always be trained teachers waiting for classes.
