The size and organization of a student affairs division or department may vary based on the size, type, and location of an institution. The title of the senior student affairs and services officer also varies widely; traditionally in the United States, this position has been known as the "dean of students", as distinguished from the academic dean or the deans of individual schools within a university. In some institutions today, student affairs departments are led by a vice president or vice chancellor who then reports directly to the president/chancellor of the institution. In other cases the head of student affairs may report to the provost or academic dean.
