In 1968, incoming university president Gregory Wolfe commented that the buildings were distressing evidence of Stalinist cubism on campus, although urban renewal chairman Ira Keller found them to be "perfectly lovely."[14] Portland State University's growth for the next couple of decades was restricted under the Oregon University System's 1929 ruling that no public university or college in Oregon could duplicate the programs offered by another, with grandfathered exclusions for the University of Oregon and Oregon State University.[15] Nevertheless, graduate programs were added in 1961 and doctoral programs were added in 1972.[3] The institution was granted university status by the Oregon State Board of Higher Education in 1969, becoming Portland State University.
