Outside of university systems, presidents are the functional chief executive officers of most standalone U.S. universities. However, a few universities, such as Syracuse University and the University of Pittsburgh, have a chancellor as their chief executive officer. There are occasional other uses of the title "chancellor." The College of William & Mary uses the term "chancellor" in the British sense, as a figurehead leader, but the actual executive of the school is the "president," not a "vice-chancellor." Some schools, such as Lubbock Christian University, give the ceremonial title of "chancellor" to a retiring university president. The Catholic University of America is headed by a president (formerly "rector"), with the Archbishop of Washington serving as chancellor, a ceremonial position but one which does require the archbishop to represent the university before the Holy See. This scenario, while not always exactly duplicated, is typical in other Catholic universities due to the Catholic hierarchy. In some schools run by Catholic religious orders, the rector of the community supersedes the president when the latter is a member of that religious order.
