The eight best secondary schools in Wales and why one came out on top

Cowbridge Comprehensive School has been officially named the best in Wales. The education establishment topped the annual Sunday Times Parent Power Guide by their exam results in summer, 2024.

Parents can also compare schools in towns, local authorities and nationally with links to information such as inspection reports, which are routinely posted online by Estyn. The 'Parent Power' guide compares state and independent secondaries in England, Wales and Northern Ireland.

Schools are ranked by performance at A-level and GCSE in summer, 2024, and IGCSEs sat in independent schools. If a school does not appear on the league table the publishers say "it is most likely because it did not respond to requests for its A-level and GCSE results, and the results could not be found in the public domain".

“As well as celebrating the academic excellence of the top schools it is fantastic to see how they are shaping their students to be ready for the 21st century."
