YSGOL GYFUN GYMRAEG GLANTAF IS A WELSH-MEDIUM SECONDARY SCHOOL IN LLANDAF AND IS ONE OF THREE WELSH MEDIUM SCHOOLS IN CARDIFF
The name 'Glantaf' means 'The bank of the river Taf' in Welsh. Of the three Welsh-medium secondary schools serving Cardiff, it was the first to be established (the others being Ysgol Gyfun Gymraeg Plasmawr and Ysgol Gyfun Gymraeg Bro Edern). Although all students speak Welsh and normally have received Welsh-language primary education, a large percentage come from homes where Welsh is not the first language.
Ysgol Gyfun Gymraeg Glantaf was founded in 1978, initially sharing premises with the English-language Glantaf High School, before expanding to occupy the entire building. Its first Headteacher was Mr. J E Malcolm Thomas, who was succeeded upon his retirement in 1995 by Mr. Huw S Thomas, and then by Mrs. Rhiannon Lloyd until summer 2010. Mr Alun Davies was then headteacher until his retirement in summer 2020.
The current Head is Mr Matthew H T Evans who was appointed to this leadership role in September 2020.
Ysgol Gyfun Gymraeg Glantaf is a Welsh-medium school, which means that all lessons and subjects are studied through the Welsh language. The social use of Welsh is also highly encouraged, in order to ensure the pupils' fluency in the language.
The school's motto is Coron Gwlad Ei Mamiaith, which translates to 'A Country's Crown is Her Mother Language'. The school colours are light and dark blue.
The school's four houses are named after Welsh saints: Dewi (house colour: yellow), Dyfrig (green), Illtud (red) and Teilo (blue). The four houses annually compete in many competitions eg Eisteddfod, athletics, cross country etc.
