On Tuesday, 773 law graduates in Michigan were locked out while taking the state’s first-time online bar exam due to a sophisticated cyber attack. Two hundred of these exam takers were able to resume the exam within 10 minutes, but the remaining students had to wait up to 37 harrowing minutes in order to regain access to the online exam.

The situation in Michigan appears to be far from unique. Last week, only four days before law graduates were scheduled to take their bar exams online, Nevada and Indiana were forced to postpone scheduled exams due to software problems. Similar stories have emerged with respect to other online tests, affecting 10,000 high-school students taking advanced placement exams and even 1,000 physicians taking their qualifying surgery exams. More generally, the restrictive anti-cheating measures—which prohibit test-takers from looking away from the screen for too long, from talking or having extraneous noise in the room and even from using scratch paper—remain largely untested.
