Recognized as a living national treasure, American Ballet Theatre annually tours the United States since its founding in 1940, and has performed abroad as the U.S. Cultural Ambassador by Presidential appointment, re-affirming its role as America's National Ballet Company®. As ABT's major education component, the Jacqueline Kennedy Onassis School at American Ballet Theatre serves approximately 300 students and encompasses a pre-professional division (ages 12-18) and Children's Division (ages 3-14). It aims to provide the highest quality ballet training, consistent with the stylistic requirements of American Ballet Theatre, and to provide dancers with a rich knowledge of classical technique and the ability to adapt to all styles and techniques of dance. The curriculum of the Jacqueline Kennedy Onassis School is ABT's National Training Curriculum, which combines scientific principles with elements from the classic French, Italian and Russian schools of training.
