The Royal Academy of Dance (RAD) is a UK-based examination board specialising in dance education and training, with an emphasis on classical ballet. The RAD was founded in London, England in 1920 as the Association of Teachers of Operatic Dancing, and was granted a Royal Charter in 1935. Queen Camilla is patron of the RAD, and Darcey Bussell was elected to serve as president in 2012, succeeding Antoinette Sibley who served for 21 years.
