North London Collegiate School claims the top spot based on % of top grades (8/9s) achieved. The highest ranked co-educational school is Latymer Upper School again, this time in #6 (#10 in 2025), followed by Highgate again, this time in #10 (last year #14). Still awaiting the results from a few schools, such as Kingston Grammar School and Tiffin Girls’ School, but the top 10 are unlikely to change. Further schools will be added and the rankings updated as results are released in the coming days.
