Gwernyfed High School is a mixed, English medium, 11-18 comprehensive school. Located between Brecon and Hay-on-Wye, the school has a large catchment area, extending from Painscastle in the north to Llangorse in the south, with 450 pupil on roll. The heart of the school is a Victorian, grade II listed, mansion house built in 1880. The second half of the school (the New Block) was constructed in 1979. The school has achieved eco school status and pupils get involved in environment activities, particularly as part of their citizenship challenge for the Welsh Baccalaureate.
