44% of College Faculty Are Part-Time. The Median Course Still Pays $3,121.

Walk into a lecture hall at almost any American college and there is close to a coin-flip chance the person teaching it is not a regular employee of the institution.▸ They are paid by the course, rehired — or not — a semester at a time, and in most cases they receive no retirement contribution and no help with health insurance for the privilege. This isn't a fringe arrangement. It is how nearly half of undergraduate instruction in the United States gets delivered.

The part-time share of the professoriate is not exploding — it's actually down from its 2011 peak.▸ What hasn't moved is the price of a course section, and that's the more damning number.

In fall 2011, per NCES Table 315.10, part-time faculty were exactly at parity with full-time — 762,355 of 1,524,469 faculty, or 50.0%.▸ A decade of enrollment declines at community colleges and a sharp pandemic-era drop (part-time headcount fell from 705,004 in 2019 to 652,933 in 2020) pulled the share down to 44.1% by fall 2022, the most recent year NCES has published. That's real movement. But 44% is still 665,234 people — nearly half of the instructional workforce — teaching under an employment status built around per-course pay, not a career-track salary.

And that per-course pay is not keeping up — it isn't even holding steady in nominal dollars, before inflation is even considered.

The AAUP's Faculty Compensation Survey — the largest annual national survey of what colleges actually pay their faculty — asks the same question every year: what's the average per-course rate at the lowest-paying institution category (religiously affiliated master's institutions) and the highest-paying one (private independent baccalaureate colleges)?▸ In the 2023-24 academic year, those rates were $3,226 and $6,481. A year later, in 2024-25, both had fallen in nominal dollars — to $3,200 and $6,320. Neither figure has been adjusted for inflation; a real-dollar comparison would show an even steeper decline. Layered onto that is a new data point the AAUP started collecting this cycle: the median starting rate — the minimum a part-time faculty member can be offered — across 555 reporting institutions was $3,121 per course in 2024-25.

Run the math a full-time course load implies: a person teaching four sections a semester at the median minimum rate earns about $24,968 a year, before any deductions — for work that, at most institutions, doesn't come with an office, a multi-year contract, or a vote in the department that employs them.

Low pay is one half of the story.▸ The other is what doesn't come with it. Among institutions that pay faculty per course section, only 32.7% put any money toward a retirement plan for some or all of them, and only 30.6% contribute to a medical insurance premium, according to the same AAUP survey. That means roughly two out of three institutions that rely on per-course faculty offer them no retirement contribution at all, and about the same share offer no help with health coverage — figures that were nearly identical the year before (34.4% and 31.5%, respectively), so this isn't a one-year blip. It's the standard arrangement.

Figures span two different data collections with different vintages: NCES counts are as of fall of each year cited; AAUP per-course pay and benefits figures are reported by academic year and reflect preliminary survey results as published, which the AAUP may revise in its final annual report.
