By the mid-1960s, exclusively female universities were declining throughout the nation. The legislature made the school coeducational in 1965, and the school was renamed Oklahoma College of Liberal Arts.[19] The Oklahoma State Regents for Higher Education assigned a new mission to the school: it was to be "experimental in nature" and was to "enroll a select group of students whose aspirations and abilities fit them for an intellectually rigorous and accelerated course of study."[20] Under the direction of the ninth President, Robert L. Martin, the university switched to a system of three equal trimesters. In an attempt to attract students interested in vigorous academics, this offered an opportunity for advanced students to quickly move through their studies and graduate early.[21] During this period the Alumni Association became active, donating funds for the building of an on-campus chapel.
