UNAM Suspends Admissions Amid AI-Related Exam Irregularities
Mexico's National Autonomous University (UNAM) suspended admissions and launched an investigation after the first fully online entrance exam for undergraduate programs reportedly showed unusually high scores and potential irregularities involving AI tools. The university established a technical commission to review the exam procedure, results, and whether applicants received unauthorized assistance.
What happened
UNAM's first fully online entrance exam for undergraduate admissions in 2026 produced unusually high scores in high-demand programs such as Medicine, Law, Actuarial Science, and Engineering.
Applicants and specialists identified statistically anomalous score patterns, and UNAM received reports of possible cheating during the online exam, alleged use of AI tools by applicants, and complaints from unsuccessful applicants about cancelled evaluations.
Reported impact
UNAM suspended temporary delivery of documents and new student registration for the 2026-2027 academic cycle while the investigation concludes.
Rector Leonardo Lomelí Vanegas stated that university access could not be compromised by applicants who received unauthorized assistance, and dozens of applicants demanded the exam be repeated in person.
Index analysis
UNAM installed a Technical Commission of 16 specialists to review the exam procedure, results, and factors affecting applicant performance.
The rector gave commission members freedom to request additional information, summon involved officials, and inquire into the procedures conducted.
