With the entrance of World War II, the college entered into a contract with the Army Air Corps to train aviation students. After World War II, enrollment swelled to more than 700 students and the school diversified and broadened into both a liberal arts and professional curriculum. The school began offering a Bachelor of Arts degree in 1946 and graduate programs by 1953. As a result of the broadened offerings, by 1957 the name was changed to Moorhead State College. In 1969, the school joined a cooperative cross-registration exchange with neighboring Concordia College and North Dakota State University, creating the Tri-College University. The school continued to increase its number of programs and by 1975, the State Legislature that year granted the school university status under the name Moorhead State University. In 1995, Moorhead State became part of the Minnesota State Colleges and Universities system. On July 1, 2000, the school was renamed Minnesota State University Moorhead via a request sent to the Board of Trustees of the system.
