Academic staff
Additional North American usage
In North American English, the word faculty is also used as a collective noun for the academic staff of a university: senior teachers, lecturers, and/or researchers. The term is most commonly used in this context in the United States and Canada, and generally includes professors of various rank: assistant professors, associate professors, and (full) professors, usually tenured (or tenure-track) in terms of their contract of employment.
Members of university administration (e.g., department chairs, deans, vice presidents, presidents, and librarians) are often also faculty members, in many cases beginning (and remaining) as professors. In some universities, the distinction between 'academic faculty' and 'administrative faculty' is made explicit by the former being contracted for nine months per year, meaning that they can be absent from the campus during the summer vacation, while the latter are contracted for twelve months per year. These two types of faculty status are sometimes known as 'nine month faculty' and 'twelve month faculty'.
Most university faculty hold a Ph.D. or equivalent doctorate degree. Some professionals or instructors from other institutions who are associated with a particular university (e.g., by teaching some courses or supervising graduate students) but do not hold professorships may be appointed as adjunct faculty.
Other than universities, community colleges and secondary or primary schools also use the terms faculty and professor to describe their instructors, but this does not hold the same status as a professor in a university. Other institutions (e.g., teaching hospitals) may likewise use the term faculty.
Faculty is a distinct category from staff, although members of both groups are employees of the institution in question. This is distinct from, for example, the British or Australian usage, in which all employees of the institution are staff, of two types: academic staff (North American faculty) and general staff (North American staff).
