So how did Purdue do it?“I always say it’s easier to explain what we didn’t do,” Daniels told me. “We didn’t try to get more money from the state. We didn’t shift from full-time faculty and fill the ranks with cheaper, part-time adjunct faculty. We haven’t driven up our percentage of international or out-of-state students,” who pay more than in-staters. Each of these measures has been taken up by other public universities, even as most have increased their in-state tuition.
