The Top IB schools in the UK are listed here based on the average points achieved by all students taking the IB Diploma in 2024.

There are two league tables - the first for schools with a cohort of 20 or more IB students and the second with cohorts of 10-19 students. Schools entering fewer than 10 candidates are not included.

Most IB schools also offer A-levels as an alternative, in which case the IB cohort is often in the minority. This is especially true of the smaller cohort IB schools. Speak to us on +44 1622 813870 for advice on choosing the best IB school for your child.
