The UK education system is divided into primary, secondary, further, and higher education. Secondary education includes Key Stage 4 (ages 14-16), where students typically pursue GCSEs (General Certificate of Secondary Education), which replaced O Levels in 1988. While O Levels are no longer offered in the UK, they remain an internationally recognized qualification.
For top-performing schools at the GCSE level, which serves a similar purpose to the former O Levels, several schools consistently rank high. These include The Henrietta Barnett School, Queen Elizabeth’s School (Barnet), Wilson’s School, and St O lave’s Grammar School. These are often grammar schools with selective admissions processes and a strong track record of academic excellence.
