Perfect homework, blank stares: Why colleges are turning to oral exams to combat AI

A growing number of U.S. college instructors are turning to oral exams to help combat an AI crisis in higher education

The assignment involves no laptop, no chatbot and no technology of any kind. In fact, there's no pen or paper, either.

Instead, students in Chris Schaffer’s biomedical engineering class at Cornell University are required to speak directly to an instructor in what he calls an “oral defense.”

It's a testing method as old as Socrates and making a comeback in the AI age. A growing number of college professors say they are turning to oral exams, and combining a variety of old-fashioned and cutting-edge techniques, to help address a crisis in higher education.

“You won’t be able to AI your way through an oral exam,” says Schaffer, who introduced the oral defense last semester.

Educators are no longer naively wondering if students will use generative AI to do their homework for them. A big question now is how to determine what students are actually learning.
