Sandfields Comprehensive School was an eleven to sixteen mixed county maintained secondary school that could accommodate 1,200 pupils. It opened in 1958 in purpose-built buildings designed by County Architect E. A. E. Evans and built from 1955 by John Morgan Ltd. (Cardiff), with the official opening taking place 7 years later in 1965. Building costs for the school amounted to £330,342. Pupils were drawn from the surrounding area of Sandfields Port Talbot. The school consisted of two main buildings on the same site, surrounded by extensive grounds and adjacent to its own playing fields.

At the time of opening, Sandfields Comprehensive School was 'the first of its kind and the largest school to be erected in Glamorgan'. Built on levelled sand in the extensive Sandfields Housing Estate at Aberavon, Port Talbot, external cladding of the school was of traditional brickwork and aluminium curtain walling, with a small amount of plastered surface and stonework. The interior was designed on traditional lines, with internal partitions being of plastered breeze concrete and a combination of polished wood block flooring and thermoplastic tiles. A notable feature of the school was the large assembly hall, designed as the focal point with terraceing for seating at the back of the ground floor and a large gallery overhead.

The school had an enhanced learning unit on site that catered for pupils with multiple learning difficulties. As part of Welsh Government's 21st Century Schools Programme, the school closed in July 2016 and was later demolished, with pupils transferring to the new Ysgol Bae Baglan School as of September 2016.
