The Universidad Nacional Autónoma de México (UNAM) will administer a control exam to validate admission scores after detecting irregularities and possible fraud [1].
This move targets the integrity of the university's selection process. As one of the most prestigious institutions in Mexico, any compromise in the admission standards could undermine the academic credibility of the incoming class.
The university said the measure was announced July 31 [1]. The control exams are scheduled to take place shortly after the release of the initial admission-exam results, which were issued in mid-July [1], [3].
University officials identified cheating and irregularities during the 2026 admission cycle [2], [4]. As a result of these findings, UNAM cancelled the admission exams for two percent of the applicants [3].
While some reports suggest the control exam may be administered to all applicants to ensure a comprehensive validation of scores [1], other data indicates that the most severe penalties were focused on the small percentage of candidates suspected of fraud [3].
Students have also raised concerns regarding the process, with some reporting technical failures in the platform used for the examinations [3]. The university said it is using the control exam to distinguish between those who legitimately earned their scores and those who may have used illicit means to gain entry.
“UNAM will administer a control exam to validate admission scores after detecting irregularities and possible fraud.”
The implementation of a secondary validation exam suggests that traditional proctoring and digital safeguards were insufficient to prevent cheating in the 2026 cycle. By cancelling results for a specific subset of students and potentially re-testing others, UNAM is attempting to maintain its rigorous entry standards against an increasing trend of academic fraud in high-stakes testing.
