(WASHINGTON) -- Stagnant faculty salaries for teaching professionals across the U.S. belie the common belief that professors' incomes are driving increased costs of higher education, the American Association of University Professors (AAUP) reported in a study released on Monday.
In a report called, "A Very Slow Recovery: The Annual Report on the Economic Status of the Profession, 2011–12," the AAUP says the overall average salary for full-time faculty members, on average, rose 1.8 percent in the 2011 to 2012 academic year.
In the past decade at public two-year colleges, published tuition and fees, excluding scholarship aid and adjusted for inflation, have increased by 44.8 percent. Faculty salaries, meanwhile, have decreased by 2.5 percent, according to the report.
Over the past decade at public four-year colleges and universities, tuition and fees have increased by 72 percent, the association said.
The cost of higher education continues to soar, rising 8.3 percent at four-year public colleges in the fall, the College Board reported.
Colleges and universities are also relying less on tenured faculty to teach classes and more on part-time faculty who may be paid as little as $2,000 to teach a course. Over 60 percent of instructional staff in 2009 were either part-time faculty or graduate students.
The average salary is $82,556 for professors, many of whom have invested years and hundreds of thousands of dollars in their own education.
The gap between the pay of college presidents and professors widens meanwhile, said the AAUP, which has 47,000 members at colleges and universities in the U.S. Between the 2006-2007 academic year and the 2010-2011 year, median presidential salaries increased 9.8 percent when adjusted for inflation.
With a three percent rate of inflation, faculty salaries actually fell by an average of 1.2 percent, the group said. The average salary increase for faculty members who remained employed at the same institution -- 2.9 percent -- barely kept pace with inflation, the group said.
Saranna Thornton, professor of economics and department chair at Hampden-Sydney College in Virginia and chair of the AAUP's Committee on the Economic Status of the Profession, was the primary author of this year's report. She said data for the last 10 academic years, 2001-2002 to 2011-2012, shows that, adjusted for inflation, the research "demonstrates unequivocally that faculty salaries are not driving up the costs of higher education."
John Curtis, director of research and public policy with the American Association of University Professors, said there are frequent assertions from legislators and others that say otherwise.
When a parent asked Vice President Joe Biden in January why college costs continue to rise, one of the reasons he pointed to was faculty pay, The Chronicle of Higher Education reported.
"Salaries for college professors have escalated significantly," Biden said during a town hall in Pennsylvania. "They should be good, but they have escalated significantly."
Curtis said the data in this year's report demonstrate that is not true.
"Over the course of a number of these annual reports, we've been making the case that the real issue is priorities," Curtis said. "Full-time faculty salaries have been stagnant, and an increasing proportion of instruction is being shifted to part-time faculty members who are poorly paid, not provided with benefits, and not provided with the support they need to do the jobs they are capable of."
As a result, he said, the proportion of higher-education spending that goes to instruction has been declining.
