The Siarter Iaith is a Welsh Government strategy to target the use of Welsh in schools across Wales. The aim of Siarter Iaith Cymraeg Campus is to promote the use of Welsh in English-medium schools, establishing a Welsh ethos and encouraging pupils and staff to develop their Welsh language skills. The Charter provides a framework for schools to follow in order to achieve the awards. There are three levels of award; Bronze, Silver and Gold.

St Cyres School was awarded the Siarter Iaith Cymraeg Campus Bronze Award in June 2023 and we are now working together to achieve the Siarter Iaith Cymraeg Campus Silver Award.
