Chang'an University is directly under the Ministry of Education and is one of the first batch of key universities under the national "211 Project", a university under the national "985 Advantageous Discipline Innovation Platform" construction, and a university under the national "Double First Class" construction. It is an important base for cultivating high-level talents, conducting high-level scientific research, and providing high-quality social services in the three major industries of transportation, land resources, and urban-rural development in China.

Chang'an University's graduate education began in 1978 and is one of the first batch of national master's degree granting units and the second batch of doctoral degree granting units. We started recruiting doctoral students in 1984. In 2007, the management of graduate students was reformed from a first level management model to a two-level management model between the university and the college. In 2012, we established the Graduate School, and in 2015, we established the Graduate Work Department, which shares offices with the Graduate School.
