university system may be headed by a chancellor who serves as systemwide chief, with presidents governing individual institutions. This is more commonly seen in university systems which were belatedly formed by grouping together already-extant colleges or universities in the 20th century, such as the State University of New York, the City University of New York, and the California State University. In many state university systems which began with a single flagship campus in the 18th or 19th century and gradually delegated operational authority to satellite campuses during the 20th century, the titles are reversed. This is the case in Arkansas, California, North Carolina, Illinois, Massachusetts, Missouri, and Wisconsin. 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. In some universities, such as Massachusetts Institute of Technology, the chancellor is a high ranking officer below the president and equal to or below the provost, who might have vice-chancellors reporting to her or him. The title "chancellor" is sometimes used in K-12 education in a sense similar to superintendent of schools, particularly in urban school districts. The New York City Schools Chancellor is the chief executive officer of the New York City Department of Education, which manages the city's public school system (the largest in the United States). The leader of the District of Columbia Public Schools system is also referred to as the chancellor. University president University president is the title of the
