#32. Departments.#--Every Sunday-school should be divided into departments. Three or four departments are possible in the smallest schools, and more are desirable in larger ones. It is usually possible to maintain the following departments in an ordinary school: (1) _The Cradle Roll_, for children too small to attend the regular sessions. These are usually under three years of age. (2) _The Beginners_, for children from three to six. (3) _The Primary_, for children from six to nine. (4) _The Junior_, for children from nine to eleven or twelve. (5) _The Intermediate_, for boys and girls from twelve to fifteen or sixteen. (In some schools, a Senior Department, coming between the Intermediate and the Adult, is recognized.) (6) _Adult_, for all over fifteen or sixteen. (7) _The Home Department_, for those who cannot attend, but who will study the lessons each week. (8) _The Teacher-Training Department_, for those who are preparing to become teachers. In many schools of several hundred or more, the Adult Department indicated above is divided into a Young Men's Department, a Young Women's Department, and a Senior Department of classes of either sex. An educational test may be required for promotion with honors from one department to the other; but transfer (without honors) may be made upon the age basis. Without departments there can be no thorough grading. #33. Departmental Organization.#--Each department should have some organization within itself, at least a superintendent in general charge. The superintendent of the department determines in what classes new scholars shall be enrolled, and carries into effect the plans of work outlined by the cabinet or the superintendent of the Sunday-school. The teachers should be especially adapted to the work of the department, and should remain in that department as long as they can do their best work there. #34. Classification (or Grading.)#--Proper classification cannot be maintained unless some one especially appointed for this purpose gives it careful attention every Sunday. Neither teachers nor scholars should be allowed to bring new members into their classes without the consent of the officer in charge of the classification, nor should new scholars be permitted to join whatever class they wish, regardless of proper classification. Eternal vigilance is the price of grading. The superintendent of classification will determine to what department the new scholar belongs, and his word should be final. #35. Promotions.#--There comes a time when a scholar ceases to belong in one department, and belongs in another. Promotions should be made regularly, and at a public service. All members of the school up to and including the intermediate scholars should be promoted at the same time, changing seats, as far as possible.
