If you're asking "what are non-tenured professors called?", you've hit on the core reality of modern academia. The answer isn't one title, but a confusing alphabet soup of them: adjunct, visiting, lecturer, instructor, postdoc. Each comes with its own subtle—and often stark—differences in pay, security, and respect. Forget the idealized image of the tenured scholar; today, over 70% of instructional staff in U.S. higher education are in these contingent positions, according to data from the American Association of University Professors (AAUP). This isn't a niche topic; it's the dominant employment model.
I spent years as a visiting professor before landing a tenure-track role. The confusion around titles isn't just academic; it impacts careers, livelihoods, and the quality of education itself. Let's cut through the jargon.

The 5 Most Common Non-Tenured Titles (And What They Really Mean)
These titles are not interchangeable. Universities use them precisely to denote specific hiring conditions and expectations. Mistaking one for another can lead to major career missteps.
1. Adjunct Professor / Adjunct Instructor
This is the most prevalent and, frankly, the most precarious title. An adjunct is typically hired on a per-course, per-semester basis. No benefits, no job security beyond the current term, and often shockingly low pay—sometimes as little as $3,000-$5,000 per course. Their primary role is teaching, with little to no expectation or support for research or service. Many adjuncts piece together a living by teaching at multiple institutions simultaneously. It's the gig economy of academia.
2. Visiting Professor / Visiting Assistant Professor (VAP)
A visiting position is usually a full-time, temporary appointment meant to fill a gap. This could be because a tenured professor is on sabbatical, a department has a sudden need, or they're trying out a potential tenure-track candidate without commitment. Contracts are often for one to three years. The pay and benefits are usually better than adjuncting, and the role may include a mix of teaching and research. It's a common post-PhD step, but it's still a dead-end if not converted into a permanent role.
My own VAP contract was for two years. It felt like a real job, but the "visiting" tag meant everyone knew I was temporary.
3. Lecturer or Instructor
These titles often denote a full-time, teaching-focused position that may be renewable. Unlike adjuncts, lecturers might have multi-year contracts, benefits, and a higher salary. However, the emphasis is almost exclusively on teaching a high course load. Career advancement is limited—there's usually no promotion ladder to a tenured role. At some universities, "Lecturer" can be a stable, long-term career, but at others, it's just a slightly more secure version of adjuncting.
4. Postdoctoral Researcher / Fellow (Postdoc)
Strictly speaking, a postdoc is a training position, not a teaching one. It's a temporary research appointment held after earning a PhD but before securing a tenure-track job. The goal is to build a stronger publication record. However, many postdocs end up teaching as part of their fellowship or to supplement income, blurring the lines. Postdocs can be critical for STEM fields, but in the humanities, they are becoming a prolonged, underpaid holding pattern.
5. Clinical or Professor of Practice
Common in professional fields like business, law, nursing, and the arts. These individuals are hired primarily for their professional expertise rather than a research pedigree. Contracts can be stable and well-compensated, but the path almost never leads to tenure in the traditional sense. Advancement is within a separate, teaching-focused track.
The key takeaway? The title tells you about the university's commitment. "Adjunct" signals minimal investment. "Visiting" or "Postdoc" signals a temporary trial. "Lecturer" might signal a dedicated teaching role with some stability. Always, always read the fine print of the contract, not just the title on the offer letter.
The Stark Reality: Contract Length, Job Security & Pay
Titles are one thing. The material conditions are another. This table lays bare the typical spectrum, but remember, there's huge variation between elite private universities and underfunded public colleges.
| Title | Typical Contract Length | Primary Duties | Job Security & Benefits | Approx. Annual Pay Range* |
|---|---|---|---|---|
| Adjunct Professor | 1 Semester / Course | Teaching only | None. No guarantee of future work. | $20,000 - $45,000 (if piecing together 6-8 courses) |
| Visiting Professor | 1-3 Years | Teaching & Some Research | Low. Ends with contract. Often includes benefits. | $45,000 - $65,000 |
| Full-Time Lecturer | 1-5 Years (Renewable) | Heavy Teaching Load (4+ courses/sem) | Moderate. Depends on renewal. Often includes benefits. | $50,000 - $75,000 |
| Postdoctoral Researcher | 1-3 Years | Primarily Research | Very Low. Training position. Usually includes benefits. | $50,000 - $65,000 (NIH guidelines influence) |
*Pay ranges are broad estimates. Geography, institution wealth, and field cause massive swings. An adjunct at a community college in the Midwest and one at NYU are in different financial universes.
The most common mistake new PhDs make? Assuming a "Professor" title, even with "adjunct" or "visiting" in front of it, comes with a middle-class salary. It frequently does not. The AAUP has extensively documented the trend toward contingent labor and its negative effects. You're often paid for contact hours only, with no compensation for grading, prep, or student advising—the bulk of the actual work.
Is There a Path Forward? Career Trajectories for Non-Tenured Faculty
This is the million-dollar question. The system often presents these roles as stepping stones, but for many, they become quicksand.
The Bridge Role (The Ideal Path): For some, a VAP or postdoc successfully bridges the gap to a tenure-track job. This works if you use the time aggressively: publish that book chapter, secure a small grant, network intensely within the department, and get stellar teaching evaluations. The department gets to "try before they buy."
The Career-Limiting Trap (The Common Reality): Multiple back-to-back visiting or adjunct positions start to look like a pattern on your CV. Search committees for tenure-track jobs may wonder why you haven't "landed" a permanent spot yet, unfairly viewing the contingent nature of the work as your shortcoming. The lack of research support and crushing teaching loads make publishing difficult, further eroding your competitiveness.
The Alternative Academic ("Alt-Ac") Pivot: Many smart people use these roles as a way to transition out of the traditional academy. The skills gained—teaching, public speaking, curriculum design, mentoring—are highly valuable. I've seen former VAPs move successfully into university administration, student affairs, educational technology, nonprofit work, or corporate training. The key is to consciously build a narrative that connects your academic experience to the new field.
The Stuck Scenario: This is the harsh truth nobody wants to talk about. Some faculty, especially adjuncts, become institutionally essential but professionally invisible. They teach core courses year after year but are denied the pay, security, and voice of their tenured colleagues. It's a exploitative equilibrium that hurts everyone, especially students who have less access to stable mentors.
My advice? Set a hard time limit for yourself if your goal is a tenure-track job. Two VAPs or postdocs, maximum. After that, the odds drop precipitously, and it's time to seriously pivot to an alt-ac path for the sake of your financial and mental well-being.
