The University is established since its creation three units, which are located in Iztapalapa, Azcapotzalco and Xochimilco, with the idea of promoting decentralization and allow the full development of each.

Subsequently, it was decided that their internal organization would be composed of divisions and academic departments, creating a contrast with the Schools and Colleges of existing universities. Each division would group different areas of knowledge and related disciplines each department, in order to give a flexible structure that prevents the lag that education has suffered in relation to the progress of science.
