The complex of buildings is situated on the precipitous bank of the Rotten Calder Water, overlooking a meander named the 'School Bend'.

The school derives its name from the Calder Glen (gorge) which the river occupies, which is a site of special scientific interest (SSSI).

The school has a potential pupil roll of approximately 1800, with 130 teachers, making it one of the largest secondary institutions in Europe.

After consideration by South Lanarkshire Council, it was proposed to merge the two, and rename the new school Calderglen High.
