Blue Mountains Grammar School was established in Springwood, in 1918, as the Blue Mountains Church of England Grammar School for Boys and in 2018 will proudly celebrate its Centenary.
In 1951 the School, with enrolments of 17 students, moved to its current site in Wentworth Falls and merged with the MacLaurin School for Boys (Leura). The MacLaurin tartan remains a major feature of the School's uniform and elements of the MacLaurin family crest have been incorporated into the School crest.
In the mid- to late-1970s, BMGS became a co-educational School and today has more than 600 students enrolled.
In 2003, the School opened its Valley Heights Campus (Preparatory School, Years Pre-K to 4) approximately one kilometre from the original Springwood site ("Homedale").
The School has an excellent archive at Coorah House, which can be optimised and viewed by appointment.
