During World War II, when Paris was occupied by Nazi Germany, Bardot spent more time at home due to increasingly strict civilian surveillance. She became engrossed in dancing to records, which her mother saw as a potential for a ballet career. Bardot was admitted at the age of seven to the private school Cours Hattemer. She went to school three days a week, which gave her ample time to take dance lessons at a local studio, under her mother's arrangements. In 1949, Bardot was accepted at the Conservatoire de Paris. For three years she attended ballet classes held by Russian choreographer Boris Knyazev. She also studied at the Institut de la Tour, a private Catholic high school near her home.
