Proctored exams score 10-15% lower than unproctored ones
That gap isn't because proctored exams are harder. A study in Computers in Human Behavior Reports found that students scored significantly lower on proctored online exams than unproctored ones. The researchers interpreted this as direct evidence that cheating was happening in the unproctored condition. For any online exam platform handling high-stakes certifications or hiring decisions, the implication is clear: some form of integrity control isn't optional. It's what separates a meaningful score from a meaningless one.
