Cardiff Sixth Form College has retained its spot at the top of the tree when it comes to A-level performance among independent schools.

The college achieved a 88.5 per cent A-A* rate or equivalent, one of only schools to surpass 85 per cent when it comes to this measure according to the Independent Schools Council (ISC).

Our interactive league table allows you to search these results by specific school and compare schools of your choice against one another.

Some independent schools decline to release their results in this fashion so it may be possible that there is a better performing school out there. However, Cardiff Sixth Form College is the best among the roughly 300 schools who entered at least 10 candidates and agreed to have their results published.

Westminster School came second in our table with 88.1 per cent A-A* or equivalent, while North London Collegiate School is third with 84.8 per cent.

This year’s A-level exam results have revealed that 7.4 per cent of pupils from independent schools obtained three A*s.

The percentage of entries getting an A* at A-level is 17.7 per cent, more than twice that of the national average of eight per cent.

At 47 per cent, almost half of A-level entries at ISC schools received either an A* or an A – compared to the national average of 26.4 per cent.

This rate among the 75,470 entries at 325 ISC schools is significantly higher than the national A* attainment of 8.3 per cent.

Barnaby Lenon, chairman of ISC, said: “Ultimately, schools want to provide an education that best meets the needs of each pupil. It is therefore hugely beneficial to students that independent schools are looking at a diverse range of routes for them to take, including vocational.

“Whatever their next steps in life, our Year 13 students and their teachers deserve to be congratulated for another impressive set of exam results – efforts made more noteworthy given their strong performance comes amid major exam reforms.”


The table covers A-levels in addition to the International Baccalaureate (IB) and the Cambridge Pre-U. Results in the IB and Pre-U are converted into A-level equivalents. A previous version of this article only included A-levels.

Higher level 7 and 6 at IB and Distinction 1, 2, 3 and Merit 1 at Pre-U are equivalent to A* and A at A-level. Schools have been ranked by their rate for A*-A grades or equivalent. Schools are tied, marked with “=”, if their score is exactly the same. Otherwise, a tie is decided by differences at two decimal places.
