In 1972 the local authority in Glasgow abolished the selectivity process and the school gradually became a comprehensive school serving its geographical catchment area of Glasgow's West End, and serving many pupils from wider afield who had attended the primary school.

It also uses the nearby Wellington Church for mass assemblies at October, Christmas, Easter and Summer.

Also in the Main Building is the library, where a career and exam advisor makes biweekly appearances.

The main building was designed by E G Wylie in 1921, and construction finished in 1929.
