Metal-framed glasses for the exam: Korea answers AI cheating with visual inspections, leaving families to improvise

By Korea JoongAng Daily · November 2, 2026.

With less than a month to go before the CSAT (College Scholastic Ability Test, South Korea's university entrance exam, scheduled for November 19), many families are replacing their children's glasses. According to the newspaper, the reason is to keep their black plastic frames from being mistaken for AI smart glasses, which are banned from the exam. One parent quoted by the outlet spent about 170,000 won (around $130) on metal-framed glasses for his son, a high school senior.

On October 15, the Ministry of Education sent a notice to regional education offices to tighten monitoring and explain how to identify smart glasses. It later presented an additional plan. According to the outlet, it includes criminal complaints against students caught cheating and extending the exam ban penalty from one to three years. It also plans to deploy about 1,300 additional staff at test centers.

The problem is detection. According to the ministry itself, radio-frequency detectors (equipment that picks up the wireless signals emitted by connected devices) will not be available at test centers until next year at the earliest. Until then, checks will depend on proctors' visual inspection. And smart glasses are designed to look like ordinary black plastic-framed glasses, exactly the kind many students wear.

The teachers' union KTU warned, according to the article, that proctors are caught in a bind: if they mistake ordinary glasses for smart ones, the student can complain that their exam was disrupted. If they fail to spot smart glasses, they may be held responsible for poor supervision. A professor at Gyeongin National University of Education noted that the criteria will vary from one center and one proctor to another.

**Our take.** Thesis: this story is not about glasses, but about the gap between the speed of consumer technology and that of institutions. Punishment has been toughened (criminal, and three years) before there is a reliable method to detect the violation. That shifts the risk onto the most vulnerable: students who have done nothing wrong and who, weeks before the most important exam of their lives, must decide whether to change glasses or accept more scrutiny. It is also an unfair burden on proctors, who are asked to make a judgment that neither technology nor the rules support.

In the short term, we are likely to see more episodes like this. Devices with built-in AI (cameras, microphones, assistants) will become increasingly discreet, and in-person "zero-assistance" exams will become hard to guarantee by sight alone. In general, the reasonable solutions are technical (signal detection, jamming in exam rooms) and also about design: tests that assess reasoning and not just memorization, something AI itself is forcing us to rethink in assessment.

In the long term, we see an opportunity. If every student will have an AI tutor within reach, society will have to decide what it wants to measure with an exam and why. It is an uncomfortable transition, and Korea is living through it very visibly, but it will push toward an education system less reliant on a single one-day test. In the meantime, the bare minimum is that the rules be clear, uniform and not penalize those who simply need to see well.
