Founded in 1929, Urmston Grammar was initially co-Ed but in the early 60s a new Urmston Grammar School for Boys was built due to overcrowding at Newton Road.

These include the Reading Room, the Theatre and the Fitness Suite as well as a state of the art Music Room which was opened by George Fenton. The school offers a secure environment with access to the very latest facilities, including cloud access and campus wide WiFi. Urmston Grammar was awarded specialist Science College status in 2004 and later, in 2007 it was awarded High Performing Specialist College status, and as from April 2008 Language College status as a second specialism. Urmston Grammar School converted to academy status as of September 2010, where it was 1 of the first 32 schools to convert, since then it has been known as Urmston Grammar.
