You can access the full reports HERE. The authors use the data to justify some conservative talking points that don't directly follow. But the data alone is really worth thinking about.
Here's some of the summary.
Enrollment at America’s leading universities has been increasing dramatically, rising nearly 15 percent between 1993 and 2007. But unlike almost every other growing industry, higher education has not become more efficient. Instead, universities now have more administrative employees and spend more on administration to educate each student. In short, universities are suffering from “administrative bloat,” expanding the resources devoted to administration significantly faster than spending on instruction, research and service.
Between 1993 and 2007, the number of full-time administrators per 100 students at America’s leading universities grew by 39 percent, while the number of employees engaged in teaching, research or service only grew by 18 percent. Inflation-adjusted spending on administration per student increased by 61 percent during the same period, while instructional spending per student rose 39 percent. Arizona State University, for example, increased the number of administrators per 100 students by 94 percent during this period while actually reducing the number of employees engaged in instruction, research and service by 2 percent. Nearly half of all full-time employees at Arizona State University are administrators.
I wish the authors showed the extent to which these numbers are merely the result of a widening pay disparity between administrators and faculty, and which percentage are the result of hiring more administrators.
