TABLE IX.-Distribution, by grades and ages, of pupils enrolled during the year 1914–15— Continued.

TABLE X.-Promotion of pupils enrolled during the year 1914-15.

ELEMENTARY URBAN DAY SCHOOLS.

NOTE.-In the foregoing tables on the promotion of pupils in the elementary day schools the number of pupils enrolled (column 2) is the total of pupils enrolled during the year, exclusive of duplicates. They are classified according to the grade each pupil belonged to on entering school. The promotions include those made during the year as well as at its close. In some cases pupils were promoted twice, once during the year, and again at its close. These are indicated in column 7. Their first promotion is included in the columns 3 to 6. Their second promotion was evidently made after less than a year spent in the grade. The whole number of pupils, including these duplicate promotions, found in each grade during the year is found by adding to the number originally enrolled in the grade the number of twice-promoted pupils in the next lower grade. The twice-promoted pupils must also be added to the pupils promoted after less than a year in the grade. These changes have been made in the following table, which shows the number and per cent of promotions from each grade according to the time spent in the grade.
