U.S. academic ranks of assistant professor, associate professor, or professor
Professors in the United States commonly occupy any of several positions of teaching and research within a college or university. In the U.S., the word "professor" is often used to refer to anyone who teaches at a college of university level at any academic rank. This usage differs from the predominant usage of the word professor in other countries, where the unqualified word "professor" only refers to "full professors" (i.e., the highest rank among regular faculty), nor is it generally used in the United States for secondary education teachers. Other tenure-track faculty positions include assistant professor (entry level) and associate professor (mid-level). Other teaching-focused positions that use the term "professor" include Clinical Professor, Professor of Practice, and Teaching Professor (specific roles and status vary widely among institutions, but usually do not involve tenure). Most faculty with titles of "Lecturer" and "Instructor" in the U.S. are not eligible for tenure (as of 2015[ [update]]), though they are still often referred to as "professors" in a general sense and as a courtesy form of address. Non-tenure-track positions may be full or part time, although the qualifier "adjunct" always denotes part-time (whether combined with the word "professor" or not).
Research and teaching are among the main tasks of tenured and tenure-track professors, with the amount of time spent on research or teaching depending strongly on the type of institution. Publication of articles in conferences, journals, and books is essential to occupational advancement. In 2011, a survey conducted by TIAA-CREF Institute senior researcher Paul J. Yakoboski estimated that 73% of professors with senior tenure ranged between the ages of 60 and 66 and that the remaining 27% were above the age of 66. Yakoboski estimated that 75% of these professors have acknowledged that they have made no preparations for retirement due to the ongoing financial crisis and reluctance to leave their profession. A 2013 survey conducted by Fidelity Investments would echo similar results when the question about retirement came up.
In 2020, the National Center for Education Statistics counted 189,692 professors, 162,095 associate professors, 166,543 assistant professors, 96,627 instructors, 44,670 lecturers, and 164,720 other full-time faculty.
Overview.
The term "professors" in the United States refers to a group of educators at the college and university level. In the United States, while "Professor" as a "proper noun" (with a capital "P") generally implies a position title officially bestowed by a university or college to faculty members with a PhD or the highest level terminal degree in a non-academic field (e.g., MFA, MLIS), the common noun "professor" is often used casually to refer to anyone teaching at the college level, regardless of rank or degree. At some junior colleges without a formal ranking system, instructors are accorded the courtesy title of "professor".
Although almost all tenured professors hold doctorates, some exceptional scholars without them are occasionally granted tenure: Jay Forrester (electrical engineering, M.I.T.) had only a master's degree; Saul Kripke (philosophy, Rockefeller) and Andrew Gleason (mathematics, Harvard) had only a bachelor's degree; Edward Fredkin (computer science, M.I.T.) and Erik Erikson (psychology, Harvard) did not even have bachelor's degrees. Tenure without a doctorate is somewhat more common in fields with an artistic component, as with Howard Nemerov (poetry, Washington University in St. Louis) and Colin Rowe (architectural history and theory, Cornell). Until the middle of the 20th century, professors without doctorates were more common.
Tenured and tenure-track positions.
These full-time faculty members with PhDs or other highest-level terminal degrees (designated as acceptable by a university or college, including the "professional equivalent" to the doctorate at institutions such as Columbia University), engage in both undergraduate and graduate teaching, mentoring, research, and service. Only faculty in these positions are eligible for tenure.
The top administrative post in many academic departments is the "department chair." Prior to the 1970s, such administrators were called "chairmen" or "chairwomen", but the term in most institutions has since been the gender-neutral "chairperson", or shortened to "chair". While many department chairs also hold endowed chair positions, the two positions are distinct.
Educators who hold a formal title of "Professor" (referred to as tenured/tenure-track faculty) typically begin their careers as "assistant professors" (or "lecturers" and "senior lecturers"), with subsequent promotions to the ranks of "associate professor" and finally "professor". The titles are historical traditions; for example, it is not implied that an assistant professor "assists" more senior faculty. There is often a strict timeline for application for promotion from assistant to associate professor, most often 5 or 6 years following the initial appointment. Applicants are evaluated based on their contributions to research, teaching, and administration. The relative weightings of these contributions differ by institution, with PhD-granting universities usually placing more emphasis on research and liberal arts colleges placing more emphasis on teaching. The decision to grant tenure and promotion from assistant to associate professor usually requires numerous levels of approval, with a common sequence being:
A decision to reject a candidate for tenure normally requires that the individual leave the institution within two years (under the AAUP tenure guidelines). Otherwise, tenure is granted along with promotion from assistant to associate professor. Although tenure and promotion are usually separate decisions, they are often highly correlated such that a decision to grant a promotion coincides with a decision in favor of tenure, and vice versa. Promotion to associate professor usually results in an increased administrative load and membership on committees that are restricted to tenured faculty.
Some people remain at the level of associate professor throughout their careers. However, most will apply for the final promotion to full professor; the timeline for making this application is more flexible than that for assistant to associate positions and the associate professor does not normally lose his/her job if the application is rejected. As with promotion from assistant to associate professor, promotion from associate to full professor involves review at multiple levels, similar to the earlier tenure/promotion review. This includes external reviews, decisions by the department, recommendations by members of other departments, and high-ranking university officials. Usually, this final promotion requires that the individual has maintained an active research program and excellent teaching, in addition to taking a leadership role in important departmental and extra-departmental administrative tasks. Full professor is the highest rank that a professor can achieve (other than in a named position) and is seldom achieved before a person reaches their mid-40s. The rank of full professor carries additional administrative responsibilities associated with membership on committees that are restricted to full professors.
Two-year community colleges that award tenure often use the "professor" ranking system as well. Candidates for tenure at those institutions would not normally need to hold a PhD, only the degree necessary (usually a master's) for employment as an instructor.
Non-tenure-track positions.
Individuals in these positions who typically (though not always) focus on teaching undergraduate courses do not engage in research (except in the case of "research professors"), may or may not have administrative or service roles, and sometimes are eligible for job security that is less strong than tenure. They may still be referred to casually as "professor" and be described by the common-noun "professor", whether or not they officially designated that position title by the university or college. Likewise, the term "instructor" is very generic and can be applied to any teacher, or it can be a specific title (tenure or tenure-track) depending upon how an institution chooses to use the term.
Positions typically temporary and/or part-time:
Retired faculty.
Retired faculty may retain formal or informal links with their university, such as library privileges or office space. At some institutions, faculty who have retired after achieving the rank of professor are given the title "professor emeritus" (male) or "professor emerita" (female).
Tenure-track faculty ranks.
Although the term "professor" is often used to refer to any college or university teacher, there are different 'tiers' of professorship ranging from an entry-level position as an "assistant professor" to "full professor", a rank reserved for professors who have established themselves as experts within their academic fields. Contrary to some beliefs, assistant professors, associate professors, and full professors are all, in fact, technically professors. Usually students who have completed their doctoral studies seek positions as assistant professors in colleges and universities. As they progress in their established fields through research, teaching, and service, they can make bids for promotion and tenure, which typically elevates them to the rank of associate professor. Associate professors who continue to establish high profiles and become experts in their fields of study may bid for a promotion to full professor, which is considered an esteemed position reserved for the most successful professors working in their fields. College and university teachers who hold the rank of "lecturer" or "instructor" are typically not tenured/tenure-track faculty, usually focus on teaching undergraduate courses, and are generally not involved in research, nor are they typically involved in department and university decision-making. (Note that in other English-speaking countries, the term "lecturer" might have a different meaning. For example, in the United Kingdom and in Ireland, the position of lecturer is equivalent to that of assistant professor in the US system.)
Assistant professor.
The rank of assistant professor generally is held for a probationary period of five to seven years, after which the individual will either be promoted to associate professor and granted tenure (i.e., cannot be fired without cause and a formal hearing process) or will be terminated from employment. As of 2007, 23.1% of academics held the rank of assistant professor.
Competition for assistant professor positions in many fields is rapidly growing; the number of PhD graduates is rising, while the number of assistant professor openings remains roughly constant. The opposite is true, however, in business disciplines, where the anticipated shortfall of business faculty may reach 2,400 openings by 2012. The U.S. Occupation Outlook Handbook notes that a significant proportion of any growth in academic professor jobs will be due to "part-time and non tenure-track positions". As of 2003, the average age at which scientists received tenure in the United States was 39, which can make it difficult for professors to balance professional and family obligations.
The tenure process.
After several years at the rank of assistant professor, individuals are considered for a promotion and tenure. Tenure generally constitutes a lifetime employment agreement and could also serve as a means of protecting faculty whose research may be socially, politically, or scientifically controversial. Rates for achieving tenure vary, depending on the institutions and areas of study; in most places at least 50% of assistant professors will eventually become tenured and promoted to associate professors; however, this number can be as low as 10% in natural sciences departments of top universities or in non-PhD-granting schools. In unusual circumstances, it is possible to receive tenure but to remain as an assistant professor, typically when tenure is awarded early.
Associate professor.
Upon successfully receiving tenure, an assistant professor usually is promoted to the rank of associate professor. The mid-level position is usually awarded after a substantial record of scholarly accomplishment (such as the publication of one or more books, numerous research articles, a successful program of external research grant support, successful teaching, and/or service to the department); however, the specific requirements vary considerably between institutions and departments. As of 2007, 22.4% of academics hold the rank of associate professor.
Alternatively, a person may be hired at the associate professor level without tenure (which is a typical practice at some universities, often done as a financial inducement to attract someone from outside the institution, but who might not yet meet all the qualifications for tenure). If an applicant is appointed to the rank of associate professor without tenure, the position is usually tenure-track with an expectation that the person will soon qualify for tenure.
At some institutions, individuals are promoted to the rank of associate professor prior to receiving tenure. In these situations, the individual may eventually apply for tenure at that institution or, optionally, seek a tenured position elsewhere.
Professor.
Upon a sustained and distinguished track record of scholarly achievement within one's university and academic discipline, an associate professor may be promoted to professor (sometimes referred to as "full professor"). In most traditional colleges and universities, this position is always tenured; however, this may not be the case in a for-profit private institution or certain church-affiliated universities and colleges.
The rank of professor is the highest of the standard academic ranks in the United States, and is held by 29.5% of U.S. academics. Advancement
