One way or another, in 1938 Monción was offered a scholarship to the recently established School of American Ballet, founded by the renowned Russo-Georgian-born choreographer George Balanchine, alongside Edward Warburg, and of course, Lincoln Kirstein. The school, which had only opened in 1934, had just begun recruiting male students at a time when few males in America were making their way into classical ballet. The School of American Ballet was looking to fill their roster, and so they accepted Monción as a scholarship student despite his dearth of experience. As a result, Monción only began professional dance training at twenty years old, an incredibly late age for any dancer to be starting out. Nevertheless, he immediately found himself in technique classes taught by the likes of accomplished dancers such as Pierre Vladimiroff, Anatole Oboukhoff, and Balanchine himself. Much like someone thrown into the deep end of a pool without knowing how to swim, Francisco was forced to adapt quickly.
