In 1939 it became a four-year institution, and in 1941 was renamed Pembroke State College for Indians. The next year, the school began to offer bachelor's degrees in disciplines other than teaching. In 1945 the college was opened to members of all federally recognized tribes. A change of name to Pembroke State College in 1949 presaged the admission of white students, which was approved in 1953 for up to forty percent of total enrollment. The "Brown v. Board of Education" ruling the following year by the United States Supreme Court ended race restrictions at the college. Between 1939 and 1953, Pembroke State was the only state-supported four-year college for Indians in the United States.
