BOSTON ( TheStreet) -- The average rate of college tuition and fees in the United States has increased 440% in the past quarter-century, with an increase of 70% in just the past decade. There has been a lot of speculation about causes, and a report released this month by the nonprofit Delta Cost Project tries to shed some light.
According to the report, Labor Intensive or Labor Expensive: Changing Staffing and Compensation Patterns in Higher Education , the exponential growth of the higher ed workforce is at least partly to blame for the rising cost of college.
The report finds that the number of non-faculty staff positions at colleges and universities rose 28% between 2000 and 2012. The bulk of these positions (accounting for 20% to 25%) have been administrative, with the biggest growth in student services. The report contends that the increasing cost of college can also be correlated to the associated benefits packages for these staff positions and declines in state funding.
"When we look at the growth in administrative staff, it's the hiring for new professional support positions -- such as business analysts, counselors, admissions staff -- rather than executive positions that's driving the increase in these types of jobs," says Donna Desrochers, principal researcher at the Delta Cost Project and an author of the report.
What is not driving up the price of college: faculty wages. The project found that over the past decade faculty wages have remained essentially flat. Not only that, but many full-time faculty positions have been replaced by part-time adjuncts, who now make up about 76% of college-level instructors in the U.S. This is especially the case at public colleges.
