1. Primary schools of Kristiana exclusive of schools for abnormal children. 2. Classes requiring special individual attention. This table speaks for itself and needs no explanation. It is worthy of note, however, that in comparatively few instances do the ages vary more than two or three years, and that six years is the widest difference in age to be found among all the pupils of any given grade of work. Furthermore, we call attention to the fact that those above normal age in no year aggregated as much as ten per cent of the entire number in attendance. 10.1 per cent represents the entire number outside the normal age--those above plus those below--for the year 1908. During the three former years the percentage was still smaller. The reduction in numbers of pupils in the sixth and seventh grades is due in large part to the fact that so many pass from the fifth grade into the middle school. The same conditions of uniformity exist in the secondary schools. Having entered at the age of seven and having spent five or more years in the primary school, the pupils upon entrance to the middle school are generally twelve or more years old. In some middle schools the average age of those entering will at times be less than twelve years. This latter condition is usually due to some local situation or rule regarding age at entrance upon school work. In order to follow the age question to nearer its limits we will present Table IV.
