During the same period, the staff of full-time instructors, or equivalent personnel, rose about 50 percent, while the number of managers increased slightly more than 50 percent.
The data, based on United States Department of Education filings from more than 2,782 colleges, come from 1987 to 2007, before the current recession prompted many colleges to freeze their hiring.
Neither the report nor outside experts on college affordability went so far as to argue that the increase in support staff was directly responsible for spiraling tuition. Most experts say that the largest driver of tuition increases has been the decline in state financing for higher education.
Still, the findings raise concerns about administrative bloat, and the increasing focus on the social and residential nature of college life, as opposed to academics.
The growth in support staff included some jobs that did not exist 20 years ago, like environmental sustainability officers and a broad array of information technology workers. The support staff category includes many different jobs, like residential-life staff, admissions and recruitment officers, fund-raisers, loan counselors and all the back-office staff positions responsible for complying with the new regulations and reporting requirements college face.
“A lot of it is definitely trying to keep up with the Joneses,” said Daniel Bennett, a labor economist and the author of the center’s report. “Universities and colleges are catering more to students, trying to make college a lifestyle, not just people getting an education. There’s more social programs, more athletics, more trainers, more sustainable environmental programs.”
In the 20-year period, the report found, the greatest number of jobs added, more than 630,000, were instructors — but three-quarters of those were part-time. Converted to full-time equivalents, those resulted in a total of 939,00 teaching jobs, up from 614,000 in 1987.
The largest number of full-time jobs added, more than 278,000, were for support staffs, and grew to more than half a million positions in 2007, from 292,000 in 1987. Colleges also added some 65,000 management positions, almost all of them full time; all told, they had 185,000 managers in 2007, up from about 120,000 managers 20 years earlier.
