On June 14, two days after the 2026 high school graduation exam, a candidate posted on social media alleging that an invigilator at Cam Pha High School in Quang Ninh Province had suggested allowing another candidate in the same examination room to look at their answers, while also putting the candidate under psychological pressure during the exam.

The Quang Ninh Department of Education and Training subsequently investigated the allegation and disciplined three teachers involved.

To Van Tien, the second invigilator in the examination room, received a warning for failing to properly perform his assigned duties. Tran Thi Bich Hao, who as a teacher was fully aware of examination regulations but nevertheless asked Tien to commit a violation, was also given a warning. Vu Ngoc Ha, the first invigilator, received a reprimand for failing to stop Tien’s violation and failing to report it to the head of the examination site.

Several days after the Ministry of Education and Training announced the graduation exam results, authorities analyzing the data detected unusual results at the Tuyen Quang Provincial Examination Council.

At the examination site at Tuyen Quang High School for the Gifted, 328 candidates sat the exam, including six independent candidates. Yet as many as 147 Mathematics papers received a perfect score of 10, accounting for more than 95% of all perfect Mathematics scores in the province.

The results were considered unusual when compared with the province’s educational performance over many years. In addition to the 147 perfect scores, candidates with consecutive or closely numbered candidate IDs mostly achieved high marks, with only three scoring below 8.

Following a review and investigation, on July 8, Tuyen Quang Provincial Police launched criminal proceedings against and detained Nguyen Ha Duy, born in 1998 and a teacher at Tuyen Quang High School for the Gifted, on charges of abusing his position and authority while performing official duties under Article 356 of the Penal Code.

To date, the Tuyen Quang Provincial Police Investigation Agency has initiated proceedings against 27 defendants in connection with the case involving alleged abuse of position and authority while performing official duties at the Tuyen Quang High School for the Gifted examination site during the 2026 graduation exam.

The Ministry of Public Security’s Security Investigation Agency has since decided to take over the case for further investigation and handling.

In Quang Tri Province, social media posts appeared on July 10 alleging misconduct at the Le Truc High School examination site.

According to the posts, several invigilators and members of the examination council allegedly guided or provided answers to certain candidates, including the child of the school principal and the children of two other teachers at the school. The posts also alleged that some candidates communicated with one another while taking the exam.

On July 19, the Security Investigation Agency of Quang Tri Provincial Police launched a criminal case and initiated proceedings against two teachers in connection with misconduct at the Le Truc High School examination site. They are being investigated for abusing their positions and authority while performing official duties.

According to the Quang Tri Department of Education and Training, preliminary investigation results identified two teachers and nine candidates as directly connected to cheating during the 2026 high school graduation exam.

The two teachers facing criminal proceedings are Tran Duc Luc, head of the Mathematics department and deputy head of the Le Truc High School examination site, and Doan Thi Thanh Binh, head of the Literature department and secretary of the examination site.

In Khanh Hoa Province, the provincial Department of Education and Training said on July 15 that it had investigated a report alleging that a candidate at the Ngo Gia Tu High School examination site used unauthorized materials and a mobile phone during an exam but was not dealt with in accordance with regulations.

The investigation team determined that the candidate had brought a mobile phone into the examination room. An invigilator discovered and confiscated the device while the exam was underway.

However, investigators found insufficient grounds to conclude that the candidate had brought paper cheat sheets into the examination room, as had been alleged on social media.

Based on the findings, the Khanh Hoa Provincial Council for the 2026 High School Graduation Exam decided to cancel all of the candidate’s examination results for violating regulations.

The Khanh Hoa Department of Education and Training will meet to consider disciplinary measures for personnel involved in invigilation at the Ngo Gia Tu High School examination site after the completion of the exam re-marking process.

In Ca Mau Province, a social media post appeared on July 11 alleging that a candidate from Ho Thi Ky High School had used a mobile phone inside an examination room during the 2026 graduation exam.

On July 20, a leader of the Ca Mau Provincial People’s Committee confirmed that authorities were aware of the case and were reporting it to seek further instructions on how to proceed.

According to a VietNamNet source, during preliminary discussions with provincial authorities, the candidate, identified as T.T.Q., a Grade 12 student at Ho Thi Ky High School, admitted using a mobile phone during the Mathematics exam.

A leader of the Ca Mau Department of Education and Training said the candidate’s examination results would be canceled and that relevant organizations and individuals would also be dealt with in accordance with regulations.

In Bac Ninh Province, numerous social media posts have circulated in recent days alleging that a candidate from Luong Tai High School received direct assistance from invigilators in solving Mathematics and English questions during the 2026 high school graduation exam.

According to the posts, the candidate scored 10 in Mathematics and 9.75 in English despite claims that the student’s previous academic performance had not been particularly strong.

Speaking to VietNamNet on July 21, Hoang Van Quy, Principal of Luong Tai High School, said the information circulating on social media was untrue.

Earlier, social media posts had also raised questions about another candidate at the Luong Tai High School examination site who scored 9.5 in Mathematics despite receiving only 2.7 in the first mock exam.

Authorities in Bac Ninh are continuing to verify the information before reaching an official conclusion. They have also said action will be taken in accordance with regulations if anyone is found to have spread false information that damages the credibility of the examination.
