Have you ever wondered how class sizes vary around the world?

Student learning and quality of education are often linked to the number of students in a class, with studies showing that smaller class sizes and more beneficial for children's development, attainment and pro-active learning. But which countries around the world put the most pressure on their teachers with bigger class sizes? To draw the light on this, we have created a graphic analysing the average class size across 40 countries.

The graphic below reveals the teacher-student ratio around the world, showing the number of students to one teacher in the average class size in each country.

The UK comes 10th from the bottom with the average class size sitting at 17 students to one teacher despite this, the UK has seen a 46% decrease in class sizes over the past 4 years. Belgium’s class sizes have seen the biggest impact, with the average class increasing by 109% over the past 4 years.
