How large are primary school classes in the UK, compared with other countries?

What this table establishes

The table establishes the average class size in public primary schools for the year shown.

It does not establish why countries differ, what any country should spend or provide, or that a rank is a judgement on a health or economic system.

How it is made

Each row is the figure the publisher printed, in pupils per class, public primary schools. Rows are ordered highest first; nothing is estimated, weighted or adjusted by Civometry.

Public institutions, primary level. Class size is not the pupil–teacher ratio, which also counts staff outside the classroom.
