Entry information reviewed 23 September 2026. A published proposal for future rule changes is not treated here as an adopted entry rule.
Vietnam’s route runs through the national excellent-student examination in mathematics and a later Olympic team-selection examination. The national mathematics paper is often called VMO in English. Registration begins with the school and the responsible education unit, rather than a direct application to the IMO.
Start with your school’s mathematics department
Ask how students are selected for the team entered by your provincial education department or your school’s responsible university unit. Find out the local selection date, training arrangements and nomination requirements. The Ministry’s national 2025–26 results notice addresses provincial departments and institutions with participating specialist schools.
Do not assume that being in a particular grade or winning a local prize automatically secures a national entry. The school can identify the current regulations and the notice governing its selection.
National examination and team-selection examination
The national excellent-student examination, Kỳ thi chọn học sinh giỏi quốc gia THPT, comes before the separate Kỳ thi chọn đội tuyển Olympic. In the completed 2025–26 cycle, the Ministry listed a mathematics score of 26.00 or more for invitation to the March 2026 selection examination. That threshold is a historical example, not a forecast for the next cycle.
The 2026 Olympic selection results were announced on 2 April 2026. Read the mathematics attachment for that stage. A national prize list and the final international team list answer different questions.
Which rules should you use now?
The ministry published proposed changes in August 2026. A proposal does not by itself establish the rules for the next examination. Ask your school for the final regulation and annual instructions before relying on a new quota, eligibility condition or timetable.
Past papers and solutions
The Ministry released the 2025–26 national examination papers and answers on 19 January 2026. Its announcement links a multi-subject collection: choose mathematics (Toán) and check the day and year on each file. The national exam and the later Olympic team-selection exam are different papers.
