[4] The Penarth Learning community is a key element to the schools investment program[clarification needed] with the funding scheme provided by the Welsh Government and Vale of Glamorgan Council under the Government's 21st century program.

The site is located on the western edge of Penarth and the new build spreads onto the old St Cyres playing fields.

In 2008, St Cyres was granted "Fairtrade status" by Fair Trade Wales and became the first secondary school in Penarth to be so recognised.

[7] The competition started in October 2007 and ran until June 2008, organised and partially sponsored by The Share Centre.

The idea was conceived by ex- Real Radio Wales Richard Hopkin, who is now a music teacher at the school.

The channel also uploads the occasional humorous video, notably the St Cyres Teachers Baked Bean Challenge, which helped raise money for the Children In Need Foundation 2019.

St Cyres was also one of the first schools to offer the qualification at Intermediate level (GCSE).
