Education

Number of Classes and Class Size by Level

Data from Jan 1982 to Jan 2025

Last updated: 02 Jan 2026, 15:56 SGT

MOE (Ministry of Education)

(1) Class size is the average number of students per class, calculated by dividing the number of students enrolled by the number of classes in that level. The classes here refer to form classes only. The actual class size can be smaller for some subjects and lessons, depending on the learning needs of the students or programme considerations. For instance, levelling up programmes such as the Learning Support Programme for lower primary students, School-based Dyslexia Remediation programme and coursework subjects like Design and Technology at secondary level are conducted in smaller classes.

(2) Students in Mixed Level schools are classified according to the level they are in.
