Of the different trustees, the governor is usually required to appoint eight trustees "for the public interest" with the advice and consent of the Senate. It is through these trustees, along with the incumbent political officeholder which serves as exofficio, the way in which the governor and the political party in power effectively control the state university. The faculty and student trustees are appointed by the community of the university system. Two of the "public interest trustees" are appointed to nine-year terms, another two are appointed to seven-year terms, and the remaining four are appointed to five-year terms. The faculty and student trustees serve one-year terms. Trustees "representing the public interest" may be reappointed to additional terms as long as the total time served does not exceed eight years. Trustees representing faculty or students may be reappointed to additional terms as long as they remain being a faculty or student within the system while serving.
