Class Size

Class Size:

Class size is the average number of students per class, calculated by dividing the number of students enrolled by the number of classes. In order to ensure comparability between countries, special needs programmes have been excluded. Data include only regular programmes at these two levels of education and also exclude teaching in sub-groups outside the regular classroom setting.

The class size of an overlapping or non overlapping class interval

                                    = Actual upper limit – Actual lower limit

                                    = Difference of class boundaries.

 

Illustration: The class size of the overlapping interval 10 - 20

                                    = Actual upper limit – Actual lower limit

                                    = 20 – 10

                                    = 10.

The class size of the non overlapping class interval 1 – 10  (when the intervals are 1 – 10, 11 – 20, 21 – 30, etc.)

                                    = Actual upper limit – Actual lower limit

                                    = 10.5 – 0.5

                                    = 10.
