Adjunct Professor
An adjunct professor is a contract-based, part-time faculty member hired by a university or college on a semester-by-semester basis. Unlike tenure-track faculty, adjuncts are employed primarily to teach specific courses, are paid per class, and do not have long-term job security or research expectations.

Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

Core Duties and Institutional Role
The primary responsibility of an adjunct professor is instruction. This includes preparing course materials, delivering lectures, grading assignments, and holding limited office hours for student queries. Unlike permanent faculty, adjuncts are rarely required or expected to conduct research, publish papers, or serve on university committees. Consequently, their connection to the institution is often transactional, focused entirely on the successful delivery of specific curriculum modules.
Working Conditions and Compensation
Adjunct professors face unique professional challenges, often referred to as the 'adjunctification' of higher education. They are typically paid a flat fee per course, which is significantly lower than the pro-rata salary of full-time faculty. Furthermore, adjuncts seldom receive healthcare benefits, retirement contributions, or dedicated office spaces. Because their contracts are subject to student enrolment numbers and departmental budgets, they experience high job insecurity, with many teaching at multiple institutions simultaneously to earn a living wage.
Professional Background and Motivations
Adjunct faculty generally fall into two categories: industry professionals and aspiring career academics. Industry specialists, such as practicing lawyers, business executives, or artists, teach part-time to share practical insights and give back to their fields. Conversely, many recent doctoral graduates work as adjuncts to gain teaching experience and maintain an institutional affiliation whilst searching for scarce tenure-track positions, though transitioning from adjunct to full-time faculty can be structurally difficult.
Key facts
At a glance
- Adjunct professors are hired on temporary, short-term contracts, often semester-by-semester.
- They are paid per course taught rather than receiving a salaried annual income.
- Most adjunct positions do not offer health insurance, pension contributions, or office space.
- Their responsibilities are strictly limited to instruction, excluding research and administrative service.
- They represent a significant and growing portion of the teaching workforce in modern universities.
Common misconceptions
What people often get wrong
Often heard: Adjunct professors are less qualified than tenure-track professors.
Actually: Many adjunct professors hold the same terminal degrees (PhDs) as full-time faculty and possess extensive professional experience in their disciplines.
Often heard: Adjunct teaching is a reliable stepping stone to a tenure-track job.
Actually: In practice, universities often view adjunct work as distinct from tenure-track profiles, and long-term adjuncting can sometimes make transition harder.
Often heard: Adjuncts are expected to conduct research and publish for the university.
Actually: Adjunct contracts cover teaching duties only; any research they conduct is unpaid and unsupported by the institution.
