29. A Sunday-school is organized for work when (1) the official positions are filled; (2) there are teachers for all the classes; (3) the scholars are properly enrolled and classified; (4) and it has intelligently set itself thoroughly to accomplish, in a definite way, that for which a Sunday-school stands.
30. Enrolment.—The name of every member of the school should be enrolled either in a book or by the card system. The enrolment should show not only name and address, but date of entry, birthday, date of promotion from one department to another, date of uniting with the church, date and cause of leaving the school; date of death, if necessary.
31. Classification (or Grading).—Classification consists in placing the scholars in such departments and classes as will secure for them and for the whole school the best results in the best manner. This will require that the scholars be advanced from one department to another at proper intervals, in order to meet their changing needs.
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.
