How AI Can Spot Exam Cheats and Raise Standards (ft.com)
AI is being deployed by those who set and mark exams to reduce fraud -- which remains overall a small problem -- and to create far greater efficiencies in preparation and marking, and to help improve teaching and studying. From a report, which may be paywalled: From traditional paper-based exam and textbook producers such as Pearson, to digital-native companies such as Coursera, online tools and artificial intelligence are being developed to reduce costs and enhance learning. For years, multiple-choice tests have allowed scanners to score results without human intervention. Now technology is coming directly into the exam hall. Coursera has patented a system to take images of students and verify their identity against scanned documents. There are plagiarism detectors that can scan essay answers and search the web -- or the work of other students -- to identify copying. Webcams can monitor exam locations to spot malpractice. Even when students are working, they provide clues that can be used to clamp down on cheats. They leave electronic "fingerprints" such as keyboard pressure, speed and even writing style. Emily Glassberg Sands, Cousera's head of data science, says: "We can validate their keystroke signatures. It's difficult to prepare for someone hell-bent on cheating, but we are trying every way possible."
School: Student, you are expelled permanently because our AI says you cheated.
Student: I didn't!
School: You have no recourse, we keep your money, you are gone, your life is ruined, goodbye!
Student: 'Tis a fair court!
So are we just labeling every algorithm that detects patterns "AI" now?
If you don't secure the actual test taking, why does anything else matter?
FIRST you must verify that the person taking the test is the person who's supposed to be taking the test.
SECOND you must verify that the person taking the test has only the equipment and materials allowed by the test.
THIRD, you must monitor the actual test taking to verify the rules are being followed and there isn't any communication between test takers going on.
After that, mark the tests as they are and let the rest of this just be. If you want to see how effective your test day security is, sure, use such tools to get an idea if you are missing cheaters, but you won't be able to catch them this way. If you see evidence of cheating, up your security proceedures next time.

I don't think this is a great idea. I mean, all that money to make sure students that pay tens of thousends of dollars aren't cheating mostly themselves.... it's fucking stupid and it says more about the whole idea of modern capitalism, the illusion of meritocracy and the doubtful relevance of superior education, that about the students that would cheat themselves.

ncaa student athlete don't have time for class when the team needs 40+ hours a week and when travel time makes them miss class as well.
they don't really expelled people that much any more some times they just pass them to keep that loan $$$$ coming it.
preston vue testing can do that for $50-$100 a pop. Click hear for student loan ez-pay.
This is going to be like the TSA bullshit. A 95% accuracy rate. 600 million passengers. 30 million false positives. Zero actual terrorists. But God help you if you're one of those 30 million false positives.
Yes, lawmakers and voters not understanding even basic mathematics and statistics is a big problem. They look at the accuracy rate for positives and praise a high one, but not the ratio of false positives, which makes the high accuracy rate completely irrelevant. You don't hear them present it like "if someone is flagged, chances are better than 99.999% that he or she is not a terrorist".
It's easy to create a method with 100% positive accuracy rate. Just flag everyone.
Can AI be used to identify poorly written or "stupid" "ineffective" exams?
