Incident reports
In late August 2024, Mongolian media reported a case of suspected food poisoning involving students and staff during an external summer camp activity that was not conducted on the school’s main campus. According to published reports, public health authorities investigated the incident, and affected individuals received medical attention. Subsequent clarifications indicated that the incident was associated with catering services at the camp location. No long-term health effects were reported, and the school cooperated with relevant authorities while communicating with parents regarding student safety and welfare. In early April 2026, a violent altercation ensued between two students of the 2026 class year, particularly from a 7th grade class. This incident took place during the annual artistic showcase, during which the students were preparing for the event. The argument escalated into a physical confrontation when one of the individuals forcefully squeezed a carbonated drink bottle onto the other. The ensuing fight was eventually subdued. The aftermath of the altercation resulted in the scattering of onigiri fragments and sticky soft drink across the floor. Fourteen people were caught in the crossfire of the attack, leading to discontent against the person that caused the mess.
