Olchfa School

Olchfa School (Welsh: Ysgol Gyfun yr Olchfa) is the largest secondary school in Swansea, South Wales, with approximately 1,900 pupils, including a sixth form of over 400 students. Situated in Sketty Park to the west of Sketty, it provides secondary education for GCSE and A-Level qualifications. In 2024, it was named one of the top 100 state secondary schools in the UK. Olchfa (part of the Sketty Swansea suburb) means 'washing place' in the English language.

Around 12% of pupils have a special educational need and 1.7% have a statement of special educational needs. Both of these figures are below the Welsh averages of 21.5% and 2% respectively. Nearly a quarter of pupils come from an ethnic minority background and just over 20% speak English as an additional language.

The headteacher is Julian Kennedy, who has been in post since 2023. The Welsh Government has selected the school as a Pioneer School to participate in the development of its curriculum.
