Belfairs High School opened in 1955. In 2011 the School was rebuilt under the "Building Schools for the Future" programme. Belfairs High School converted to a stand-alone Academy Trust on 11th May 2012, to be known as Belfairs Academy Trust. In 2014, encouraged by the Department for Education, the trustees of the stand-alone academy trust and the governors of Belfairs Academy agreed to convert to a multi academy trust with a view to working with good and outstanding schools and supporting weaker schools.

With effect from 1st February 2015 Belfairs Academy Trust became Legra Academy Trust, a multi academy trust, incorporating Belfairs Academy. On 1st September 2015 Darlinghurst Academy joined Legra Academy Trust and the two academies now work together in their pursuit of excellence.
