This summer, nearly 160,000 candidates participated in the entrance exam for the National Autonomous University of Mexico (UNAM), the country’s largest educational institution. For the first time ever, this exam was conducted entirely online, utilizing a "lockdown" browser alongside AI-driven webcam monitoring over several weeks from late May to early June.
The outcome was chaotic.
Results revealed a drastic deviation from historical performance, particularly among the highest scorers. Between 2021 and 2025, only 3.5% of test participants achieved a score of 100 or above on the 120-question UNAM exam. This year, however, that percentage skyrocketed to 16.3%.
The situation was even more alarming at the very top tier. Historically, 0.9% of examinees scored 110 or more during the 2021-2025 period, but this year's results saw that figure climb to 5.5%.
This unexpected surge in high scores sparked allegations of widespread cheating, prompting UNAM to establish a panel of experts to thoroughly examine the issue.
The panel has been tasked with the complex title "Technical Commission of Expert Individuals for Reviewing the Admission Process for the 2026-2027 Academic Cycle" and has recently delivered its findings. The commission recommends implementing a “control exam,” requiring applicants to take an additional test in person.
This control exam will not only affect those who gained admission based on this year's results but also anyone who would have qualified for entry using minimum successful scores in their respective programs since 2021. Approximately 58,000 individuals may be impacted, and admission to UNAM will now hinge on the outcomes of this new examination. Additional details regarding the control exam are expected soon, as classes are slated to commence on August 10, necessitating rapid action unless the university opts to postpone the start date.
As reported by Gaceta UNAM, the university's official publication, the rector has issued an apology to honest applicants who will now have to retake the exam despite having committed no wrongdoing. However, the rector emphasized that the control exam is essential to ensure fairness and equity in the admission process.
