Balanchine insisted that his first project in the United States would be to establish a ballet school because he wanted to develop dancers who had strong technique along with his particular style. Compared to his classical training, he thought they could not dance well. With the assistance of Lincoln Kirstein and Edward M.M. Warburg, the School of American Ballet opened to students on January 2, 1934, less than three months after Balanchine arrived in the U.S. Later that year, Balanchine had his students perform in a recital, where they premiered his new work Serenade to music by Tchaikovsky at Woodlands, the Warburg summer estate. The school of American Ballet became and is now a home for dancers of New York City Ballet as well as companies from all over the world.

Between his ballet activities in the 1930s and 1940s, Balanchine choreographed Broadway musicals written by such notables as Richard Rodgers, Lorenz Hart and Vernon Duke. Among them, Balanchine choreographed Rodgers and Hart's On Your Toes in 1936, where his program billing specified "Choreography by George Balanchine" as opposed to the usual billing of "Dances staged by". This marked the first time in Broadway history that a dance-maker received choreography billing for a Broadway musical. On Your Toes featured two ballets: La Princesse Zenobia and Slaughter on Tenth Avenue, in which a tap dancer falls in love with a dance-hall girl. Balanchine's choreography in musicals was unique at the time because it furthered the plot of the story.
