It was opened on 18 September 1929 as Sutton Coldfield High School. Plans for a school had begun in 1906 with sites behind Sutton Coldfield Town Hall, in Sutton Park and Rectory Park all being considered before a 6-acre (2.4 ha) field behind Beeches Walk was selected. It became Sutton Coldfield Girls School in 1962 and then changed its name to Sutton Coldfield Grammar School for Girls in the late 1990s. It is a partner school to Bishop Vesey's Grammar School which was founded in 1527.
