The Ever-Shrinking Role of Tenured College Professors (in 1 Chart)

For almost 40 years, we've been witnessing the rise of the adjuncts.

Once, being a college professor was a career. Today, it's a gig.

That, broadly speaking, is the transformation captured in the graph below from a new report by the American Association of University Professors. Since 1975, tenure and tenure-track professors have gone from roughly 45 percent of all teaching staff to less than a quarter. Meanwhile, part-time faculty are now more than 40 percent of college instructors, as shown by the line soaring towards the top of the graph.

This doesn't actually mean that there are fewer full-time professors today than four-decades ago. College faculties have grown considerably over the years, and as the AAUP notes, the ranks of the tenured and tenure-track professoriate are up 26 percent since 1975. Part-time appointments, however, have exploded by 300 percent. The proportions vary depending on the kind of school you're talking about. At public four-year colleges, about 64 percent of teaching staff were full-time as of 2009. At private four-year schools, about 49 percent were, and at community colleges, only about 30 percent were. But the big story across academia is more or less the same: if it were a movie, it'd be called "Rise of the Adjuncts."

Why should you care? For one, it's damn tough making a living as a freelance professor (full disclosure: my mother was one for many years). The AAUP reports that the median pay for teaching a single course was $3,200 at a public research university, and just $2,250 at a community college. It's also a reminder that rising college costs aren't necessarily paying for a better quality (or better compensated) faculty. Moreover, unless the burgeoning ed-tech industry finds ways to remake at least parts of college teaching, this chart shows us how schools will attempt to do more with less resources over time. It's not a particularly pretty picture.
