Below is a ranking of London schools based on their 2018 IB Diploma results. Please keep in mind that some of these schools are fiercely selective, while others are non-selective and admit a broad range of students with varying level of English and other skills, so higher ranking schools are not necessarily “better”, but you can get an idea of the overall academic profile of students at each school.
The maximum possible score is 45.0.
