UNAM’s internal audit and external investigations confirm cheating involving thousands of students across multiple faculties. The university announced a comprehensive response plan on 2 August 2026.
The National Autonomous University of Mexico (UNAM) disclosed that a systematic cheating operation was uncovered during routine exam audits at several campuses in Mexico City. The allegations involve the use of electronic devices and coordinated answer transmission during examinations in undergraduate and graduate programs. The university’s statement, released on 2 August 2026, indicated that the issue was identified through irregularities in exam scoring data and subsequent forensic analysis [1][2].
University officials, including Rector Dr. Enrique Graue [3], the Vice‑Rector for Academic Affairs, and faculty deans from the Faculties of Engineering, Law, and Medicine, are participating in the investigation. The Federal Ministry of Public Education (SEP) and the National Council for the Evaluation of Higher Education (CENEVAL) have been notified and are providing oversight [4][5]. The investigation is being conducted by UNAM’s internal audit office, an independent external auditor, and a joint task force formed with SEP representatives [6].
Scope of the Allegations
The audit revealed that at least 3,200 students across ten faculties accessed unauthorized information during exams between 2022 and 2025 [7]. Evidence includes recovered smartphones, Bluetooth earpieces, and messaging logs that show real‑time answer transmission from off‑campus sources [8]. The devices were reportedly concealed in pens, textbooks, or hidden in clothing, allowing students to receive answers without detection [9].
Multiple faculty members reported irregular patterns in exam results, prompting the university’s examination office to request a technical review. The review identified clusters of identical answer strings among students seated apart, a statistical anomaly that triggered deeper investigation [10]. In addition to electronic devices, some reports indicated the presence of “answer sheets” pre‑filled with solutions, allegedly distributed by external tutoring services [11].

Investigation Process and Institutional Response
UNAM Initiates Formal Inquiry After Widespread Cheating Allegations Surface
A coalition of university research groups and privacy watchdogs released a joint report on August 1, 2026 documenting how AI‑driven learning platforms collect,
UNAM activated its internal audit protocol on 15 July 2026, following preliminary findings from the examination office [12]. The audit team employed digital forensics to retrieve deleted communication records and conducted physical inspections of exam rooms. An external consultancy, hired under a contract with the university’s legal department, is providing independent verification of the findings [13].
On 2 August 2026, UNAM’s governing council approved a set of immediate measures: suspension of the implicated students pending disciplinary hearings, revocation of grades for compromised assessments, and the implementation of a university‑wide electronic proctoring system for high‑stakes exams [14]. The university also announced the formation of an Academic Integrity Committee to review and revise examination policies, including stricter device bans and enhanced invigilation training [15].
SEP has pledged to monitor UNAM’s corrective actions and to consider broader policy recommendations for higher‑education institutions nationwide [16]. CENEVAL will incorporate findings from the UNAM case into its accreditation review processes for the university’s programs [17].
Immediate Impact on Students and University Operations
Students identified in the investigation face disciplinary outcomes ranging from temporary suspension to permanent expulsion, as outlined in UNAM’s academic regulations [18]. Those whose grades are annulled must retake affected courses, potentially extending program completion timelines [19]. The university’s registrar office has opened an appeals process, allowing students to contest findings within a 30‑day window [20].
UNAM’s reputation, measured by national university rankings and enrollment statistics, has experienced a short‑term decline in applicant numbers for the 2026‑2027 academic year, according to data released by the university’s admissions office [21]. Funding allocations from the federal government remain unchanged for the current fiscal year, but the university is expected to submit a detailed remediation plan to secure continued support [22].
The scandal has prompted other Mexican universities to review their own examination security protocols. Several institutions reported initiating internal audits within weeks of UNAM’s announcement, citing the need to safeguard academic integrity [23]. The Ministry of Public Education has indicated that it will issue updated guidelines for electronic device usage during exams across all public higher‑education institutions [24].
SEP has pledged to monitor UNAM’s corrective actions and to consider broader policy recommendations for higher‑education institutions nationwide [16].
What: UNAM confirmed a large‑scale cheating operation involving thousands of students and announced a comprehensive investigative and remediation plan.
When: The investigation was launched in July 2026; the university’s public response was issued on 2 August 2026.
Impact: Affected students face disciplinary action; UNAM is implementing new proctoring measures and revising integrity policies, while the scandal influences broader higher‑education oversight in Mexico.
