Q: Can a student in Singapore register directly for IMDO 2026?
A: No. The organiser describes IMDO as invite-only. Its current rules say competitors are selected through ChinaMDO for China and through USMDO for all other countries. A Singapore student should therefore check the current USMDO route rather than look for open IMDO registration.
Quick facts
IMDO 2026 is scheduled for 23 August 2026. The organiser says it will be a three-hour online competition containing multiple-choice and free-response questions about medicine and disease. Competitors must be selected to represent a country and satisfy the published age, identity, and education conditions.

Last reviewed: 18 July 2026. The official IMDO rules, resources, and results pages were checked as a complete set. Qualification and scheduling can change, so verify the organiser pages before paying a fee or making travel, school, or proctoring arrangements.

What IMDO is

The International Medicine and Disease Olympiad is an international competition focused on knowledge and problem solving related to medicine and disease. The organiser says its content is set around what a student might know after the first year of a US medical school, with a minority of questions potentially going beyond that level.

This is not a general secondary-school science quiz. The stated knowledge level is substantially beyond a normal school syllabus, and the eligibility rule is based on age and college enrolment rather than the label "secondary student".

IMDO 2026 date and format

The official rules currently state:

  • date: 23 August 2026;
  • delivery: online;
  • duration: three hours;
  • question types: a mix of multiple-choice and free-response questions; and
  • focus: knowledge and problem solving related to medicine and disease.

The public rules page does not currently state every operational detail a competitor may need. Selected students should obtain the current instructions for timing, identity checks, permitted aids, platform, and supervision from the organiser or qualifying body.

Eligibility

The current organiser rules require a competitor to:

  • be selected to represent a country;
  • be 20 or younger when IMDO is held, subject to the organiser's stated possible one-month exception requested by the partner organisation;
  • be a citizen, permanent resident, or equivalent of the represented country; and
  • not already be enrolled in college by the competition date.

Countries with populations above 250 million may have eight individual representatives. Countries with populations of 250 million or fewer may have four.
