Siddal Moor School opened in September 1968. It was formed from Heywood Grammar School and the Bamford Road and Hornby Street secondary modern schools. It was originally to be the new site of the grammar school. The former site of the grammar school on Hind Hill Street became the Hind Hill Centre. It was demolished in 2006 and is now the Phoenix Centre.
As part of the specialist schools programmes, Siddal Moor School was awarded Sports College status and was renamed Siddal Moor Sports College.
The school was allocated money for the refurbishment and rebuild. The project included a new building at the front for teaching and administration with the rest of the school being refurbished. The project was finished in 2011.
