Queen Elizabeth's was founded by Lady Margaret Beaufort, the mother of Henry VII. Her father, John Beaufort, 1st Duke of Somerset, occupied the Kingston Lacy estate in the mid-15th century and Lady Margaret was brought up there. When John Beaufort died he was buried at Wimborne Minster and his daughter set up a chantry to say masses for his soul in perpetuity. Later, in her will, she included a provision that the chantry priest "should teach Grammar freely to all who come thereto". Tithes on properties belonging to her estate were assigned for the payment of the Grammar School's expenses. In 1563 Queen Elizabeth I reconfirmed the provisions of Lady Margaret’s will on condition that from then on the school be known as Queen Elizabeth's Free Grammar School in Wimborne Minster.
Grammar to Comprehensive
Until Victorian times the curriculum continued to centre on Greek and Latin. Student numbers were low until the beginning of the 20th century. At the first inspection by the new Education board in 1905 there were 27 boarders and 37 day boys. By 1929 there were 150 pupils; by 1939, 272; by 1960, 500. In 1945 QE became a voluntary controlled school under the Department of Education. The first 30 girls joined in 1953. Between 1965 and 1975 about 90% of state secondary schools in England abandoned selection and became comprehensives. As part of this sweeping change Queen Elizabeth’s Grammar School merged with Wimborne Secondary Modern and moved to the present site.
New buildings
In February 2006 it was announced that QE School would be completely rebuilt under the Building Schools for the Future programme. Additional funding was secured by making the new building a demonstration project for sustainable schools - features included a ground-air heat exchanger system and biomass boilers. The school was designed by architects Feilden Clegg Bradley in partnership with Mouchel, and constructed by Carillion. Students influenced the design from the start, working alongside the planners. The new buildings went up next to the old ones and were occupied in October 2011.
Academy
On 1 November 2014 QE converted to an academy. The managing company, Queen Elizabeth’s School, is registered in England and Wales: Company Number 8696394. When it became an academy, the school's changed to . The old URN should be used to find historical data such as performance tables.
