An elite mathematics school in south London has topped The Telegraph’s state school A-level league table, taking the top spot for the fourth consecutive year.

The King's College London Maths School, in Lambeth, took the top spot for exams sat in 2023, with A* being the average grade awarded to students.

The school, linked closely to the university, opened in 2014 and admissions are hotly contested. Pupils must get an 8 or 9 in GCSE maths, equivalent to an A*, and a 7 to 9 in physics to secure a place at the school.

Over 90 per cent of pupils go on to study at Russell Group universities, with a quarter studying at Oxbridge.

Queen Elizabeth's School, Barnet, takes the second spot for the fourth year running, having previously placed third in The Telegraph’s GCSE rankings. Wilson’s School, in Sutton, placed third on the list.

Meanwhile, Newham Collegiate Sixth Form Centre jumped seven places to reach fifth place, having sat at 23rd just two years ago.

Similar to the London Maths School, Newham Collegiate is relatively new, founded just 10 years ago and is affiliated with the University College London.

In total, seven of the top 10 schools are grammar schools.

The league table is based on each school's A-level score, which is used to measure the average grade achieved by students. The maximum score a school can gain is a 60 – the equivalent of every grade being achieved an A*.

With a score of 55, this places King's College London Maths School above the likes of top-ranking independent schools including £29,946-a-year St Paul’s Girls’ School and £37,485-a-year Westminster School.

Outside of London, Colchester Royal Grammar School performs the best with an average score of 50.5. The highest non-grammar school is Brampton Manor School in London.
