The School of American Ballet (SAB) is an American classical ballet school and is the associate school of the New York City Ballet, a ballet company based at the Lincoln Center for the Performing Arts in New York City. The school trains students from the age of six, with professional vocational ballet training for students aged 11–18. Graduates of the school achieve employment with leading ballet companies worldwide, most notably in the United States with New York City Ballet, American Ballet Theatre, Boston Ballet, and San Francisco Ballet.
The school was founded by the renowned Russo-Georgian-born choreographer George Balanchine, and philanthropists Lincoln Kirstein and Edward Warburg in 1934.  Balanchine's self- prescribed edict, "But first, a school", is indicative of his adherence to the ideals of the training that was fostered by the Imperial Ballet School where he received his training. He realized that most great dance companies were fed by an academy closely associated with it. This practice afforded scores of dancers, well versed in the specifics of his technique and choreographic style. Among the teachers there were many Russian emigres who fled the Russian Revolution: Pierre Vladimiroff, Felia Doubrovska, Anatole Oboukhoff, Hélène Dudin, Ludmilla Schollar, Antonina Tumkovsky, and Alexandra Danilova. Their intention was to establish a major classical ballet company in America, which would lead to the formation of today's New York City Ballet. The school was formed to train and feed dancers into the company. It opened at 637 Madison Avenue with 32 students on January 2, 1934, and the students first performed that June. Seventy-five years later, the School was awarded the National Medal of Arts by President Barack Obama. 
Students are chosen through audition. Children's division auditions for the 2007-08 school year included six-year-olds for the first time; previously, the youngest students were required to turn eight in the year they began their studies. Children in the younger divisions are able to perform in various ballets with the company including George Balanchine's famous The Nutcracker , A Midsummer Night's Dream , Peter Martins's Swan Lake , and The Sleeping Beauty . The most advanced students perform in a workshop at the end of each year where the heads of many prestigious ballet companies choose several of them to join their companies, including New York City Ballet. This started in 1965, when Alexandra Danilova sought and received approval from Balanchine to produce a spring workshop performance for the students. These workshops have become an important preview for many outstanding dancers.
The school also hosts a summer program, where it selects about 200 dance students from across the country to train for five weeks. This summer program is one of the most selective ballet summer programs in the country. During the summer program, students are divided into six girls' classes and two boys' classes:
- first division through fifth
- boys one through four (boys stay in the same level for two years before moving to the next)
- intermediate men
- advanced men
- second advanced men
A small group of students from the summer program may be invited to enroll in SAB's winter term.
As of June 2016, the faculty of School of American Ballet includes Peter Martins (artistic director/chairman of faculty), Kay Mazzo (co-chairman of faculty), Susan Pilarre, Suki Schorer, Sheryl Ware, Arch Higgins, Katrina Killian, Darci Kistler, Andrei Kramarevsky, Dena Abergel, Lisa de Ribere, Andrew Scordato, Allen Peiffer, Jock Soto, and Jonathan Stafford.
