The school was accredited by the Higher Learning Commission in 1932. In the 1950s and 1960s, two dormitories and a Fine Arts building were erected. The three dormitories on campus housed 350 resident students. Marymount became coeducational in 1968, which met with mixed reactions from students and faculty. A multi-purpose physical education building was erected in 1971. Basketball coach Ken Cochran was hired for the 1970-71 year and two years after Marymount had begun to admit male full-time students.[citation needed]
Cochran developed a women's program in physical education[1] and built the school into a NAIA powerhouse, racking up a record of 285–56 in eleven seasons. The Marymount team enjoyed a streak of 106 straight home court wins, reached a national ranking in 10 years, and won a third place finale in 1976.[2]
Marymount closed in June 1989,[3] in a year that had an enrollment of 653 students.[4]
