In 1972, National Center of Technology was renamed as National Institute of Technology, which was the only center of South Vietnam to train technical engineers and experts. According to the decree 010/SL/VNGDTN signed on January 11, 1974, the National Institute of Technology was merged into Thu Duc Institute of Technology and renamed as University of Technology. In the same year, Thanh Hoa Post Graduate Department (the current Environmental Engineering Faculty) was established in the College of Civil Engineering. It was the first time when the university conducted post graduate training program. After the national reunification, the university was renamed as Ho Chi Minh City University of Technology as Saigon was renamed to Ho Chi Minh City (according to the Decision 426/TTg signed by The President of the Cabinet on October 27, 1976). Being one of the three largest universities of technology in Vietnam, Ho Chi Minh City University of Technology has the mission of training engineers majoring in the fields of capital construction, industry, resources exploration and exploitation, and environment preservation to provide a force of manpower mainly for the southern areas of Vietnam.
