The new preparatory school began functioning at the San Ildefonso building with more than 700 day students and 200 live-in students.[3] The complex remained a separate entity until 1929, when the Universidad Nacional gained autonomy, meaning it became independent of the government, though still government-sponsored. The Preparatory School became part of the newly independent university system, being designated as Preparatory #1 for a short time.[4][5]
Following this, because of the increasing demand, nine more schools were built, as well as a new organizational organism called General Direction. These schools were located at the center of Mexico City, but due to the increasing size of the city and the necessity for modern buildings, they were relocated in the vicinity of the city, mainly orientated in the southern neighborhoods like Coyoacán, Xochimilco and Villa Coapa.
The original San Ildefonso College location remained open until 1978, when it closed completely. It is now a museum and cultural museum.[2][4]
Frida Kahlo was one of their many students. She attended the school in 1922.
In 1972, the School's orchestra was founded by Uberto Zanolli.
