Pencoedtre High School, formerly called the Bryn Hafren Comprehensive School,[1] is in Merthyr Dyfan on the outskirts of the town of Barry near Cardiff in Wales.

[3] The school's catchment area is the Vale of Glamorgan, stretching from Rhoose in the west to Wenvoe in the north, and to Ely in west Cardiff, with the town of Barry in the centre.

When comprehensive schools were introduced to Barry in September 1966, this was delayed for girls because of the lack of buildings.

The school ground covers 36 acres (150,000 m2), with sports fields, tennis courts, a gymnasium, a swimming pool and a recently developed fitness gym.

The school also houses a dedicated 6th form block and over 14 networked computer rooms.
