Average secondary school class size Singapore 2013-2021

According to the source: "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 program considerations. For instance, levelling up programs such as the Learning Support Programme for lower primary students, School-based Dyslexia Remediation program and coursework subjects like Design and Technology at secondary level are conducted in smaller classes."
