The school underwent significant expansion during World War II, adding additional programs in the arts and sciences as well as its School of Pharmacy. After brief periods as Southwestern State College of Diversified Occupations and Southwestern Institute of Technology, the name was formally changed to Southwestern State College by the Oklahoma Legislature. The first graduate degree, a Masters of Teaching, was added in 1953, and the school was officially designated as Southwestern Oklahoma State University in 1974.[1]
