Tudor Grange Grammar School began as an entity at Lode Heath School, Lode Lane, in September 1951, with two mixed classes 1G1&1G2. The formative school continued with these temporary arrangements until the new boys' school in Dingle Lane was opened in September 1956, the official ceremony taking place on Tuesday 23 July 1957. The cost of building the new premises is reported to have been £176,445. Six hundred boys were taught at the school whose motto was 'Omnibus prodesse' - 'to be of service to all men'
