Stanford Brings Back Proctored Exams After ChatGPT Cheating Surge

Key Takeaways

• Stanford reinstated proctored handwritten exams in April 2026 after banning them for over a century
• 49% of surveyed CS majors said they'd rather cheat on an exam than fail
• A student describes ChatGPT turning pre-existing dishonesty into the campus default

Theo Baker belongs to a unique cohort. He arrived at Stanford in fall 2022. Two months later, ChatGPT launched. His class is the first to spend an entire college career with the chatbot as a constant companion.

In a guest essay for the New York Times, Baker describes what that companionship produced: a campus where academic dishonesty shifted from exception to norm. Stanford's response was dramatic. In April 2026, the university reinstated proctored, handwritten, in-person exams. The practice had been banned for over a century.

"Just a Little Bit of Fraud"

Baker traces the problem to culture that predated ChatGPT. Stanford's reputation had already taken hits from scandals involving Theranos founder Elizabeth Holmes, crypto fraudster Do Kwon, and the Juul founders. The AI tool didn't create dishonesty. It made it easier and more attractive.

“Just a little bit of fraud”

— A Stanford classmate describing the campus atmosphere, as quoted by Theo Baker

The phrase came from a classmate discussing sponsor hardware her student club never returned. Baker adopts it as shorthand for his entire graduating class.

The examples he provides are specific. Students embezzled dorm funds. They faked Covid infections to score UberEats credits. They signed honor pledges swearing they hadn't used ChatGPT while the tool sat open in the next browser tab. One classmate signed such a pledge at a yacht party funded by venture capitalists.

That number comes from a campus-wide survey during Baker's junior year. Nearly half of computer science students preferred cheating to failure.

The Llama3-V Plagiarism Scandal

Baker's most striking example involves a research paper. Stanford students published work claiming an AI breakthrough with something called Llama3-V. It was actually a stolen Chinese model called MiniCPM-Llama3-V2.5. The scandal highlighted how easily academic fraud could scale with AI assistance.

The incident wasn't an isolated lapse. It reflected a broader pattern Baker observed throughout his four years. The tools for cheating had become sophisticated. The detection methods hadn't kept pace.

Back to Blue Books

Stanford's solution was a return to basics. The university brought back proctored in-person exams in spring 2026. Most exams are now handwritten in Blue Books, the traditional paper booklets generations of students used before digital testing.

The original ban on proctored exams was meant to signal trust in students' honor. That trust appears exhausted.

Broken Incentives

Baker doesn't blame his classmates alone. He traces the cheating culture to incentives that reward dishonesty. A Stanford computer science degree no longer guarantees an entry-level job. Junior developers now compete with the same language models students use to cheat.

The economic picture creates a strange tension. AI threatens traditional entry-level positions. Billions of dollars flow into AI startups. Education feels like an afterthought when the fastest path to a venture-backed company doesn't require actually learning the material.

Cutting corners becomes the default when corners are all that separate you from a shrinking pool of opportunities.

What Comes Next

Baker graduates in June 2026. His essay reads less like complaint and more like anthropology. He's documenting a transition he lived through, one that many institutions are only beginning to confront.

The proctored exam solution works for now. It doesn't scale to take-home assignments, research papers, or the countless other contexts where AI assistance blurs into AI replacement. Universities will need new answers. Stanford's century-old approach is a stopgap, not a strategy.
