140 Perfect Math Scores: Teacher Arrested in Tuyen Quang Exam Scandal

In a dramatic turn of events in Tuyen Quang province, Vietnam, a 28-year-old math teacher, Nguyen Ha Duy, has been arrested on charges of "Abusing position and power while performing official duties." The arrest, executed on July 6 by the Tuyen Quang Provincial Police's Investigative Agency and approved by the Tuyen Quang Provincial People’s Procuracy, stems from an extraordinary phenomenon: an unprecedented surge of over 140 students scoring perfect 10s on the 2026 Mathematics graduation exam. Nguyen Ha Duy, a faculty member at the prestigious Tuyen Quang High School for the Gifted, is now at the center of a widening investigation into what appears to be a significant manipulation of exam results. The sheer scale of the perfect scores, concentrated exclusively at the Tuyen Quang High School for the Gifted testing site, immediately raised red flags. The crisis began to unfold on July 1, the day the 2026 National High School Graduation Exam results were released. During a routine data sweep, the Ministry of Education and Training identified glaring statistical anomalies in Tuyen Quang's mathematics scores, deeming them highly improbable. In response, a federal task force from the Ministry of Education and Training was dispatched to Tuyen Quang on July 2. They immediately embedded with local authorities to conduct a rigorous audit of the exam records and thoroughly dissect the entire testing system according to strict national protocols. Colonel Hoang Van Manh, Deputy Director of the Tuyen Quang Provincial Police, addressed the situation at a high-profile press conference on July 6. He emphasized that the case remains under active and aggressive investigation, with detectives working to uncover the full depth of the manipulation. Senior Lieutenant Colonel Pham Thanh Son, Deputy Head of Internal Political Security (PA03), confirmed that the emergency detention order for Nguyen Ha Duy was deployed the moment clear criminal violations were detected. This incident underscores the Vietnamese government's commitment to maintaining the integrity of its examination system, particularly at a time when the nation is striving for higher educational standards to support its burgeoning economy. The authorities have indicated that the investigation is proceeding under strict, urgent directives from the Ministry of Public Security, the Provincial Party Committee, the Provincial People’s Committee, and top police leadership, signaling the high priority placed on resolving this matter.
