Accordingly, the Ministry of Education and Training said that on July 2, 2026, a working group was established to inspect and verify the contents related to the exam results at the Tuyen Quang Provincial Math Exam Council.
The working group includes representatives of functional units of the Ministry of Education and Training and the Ministry of Public Security, working under the direct and regular direction of Standing Deputy Minister of Education and Training Pham Ngoc Thuong, Head of the National Steering Committee for the 2026 High School Graduation Exam.

Initially, the Task Force has not detected any unusual signs in the work of printing, copying, transporting, preserving exam papers, exam papers and grading.
