Queen Mary's High School, situated on Upper Forster Street, just outside Walsall town centre, is an all-female grammar school, with entry in Year 7 decided by the 11+ and entry into the Sixth Form decided by GCSE results.

[1] It is twinned with Queen Mary's Grammar School, and like the Grammar School is part of the Queen Mary's Foundation.

[3] The school gained an outstanding level in the Ofsted report when it was last inspected in 2021.

The school is divided into houses named after famous 19th-century female authors – Austen (after Jane Austen), Bronte (after Emily Brontë), Eliot (after George Eliot) and Shelley (after Mary Shelley), the latter being a new house in the 2012/13 academic year.

Each house has a member of staff in charge of it, a captain from Year 13 (upper sixth form) and a vice-captain from Year 12 (lower sixth form).
