The school was originally established in January 1956 as Blacktown High School. However, owing to a growing local population and in accordance with government policy, it was decided that the schools would be split into two single sex schools: Blacktown Boys and Blacktown Girls High Schools. Both were fully split by 1959.
The school also has 4 house groups. Oodgeroo, Chisholm, Reibey and Fraser; named after prominent women in Australian history.
