The Medicine Olympiad
USMDO
The US Medicine & Disease Olympiad
​
The USMDO, the US Medicine and Disease Olympiad, is America’s qualifying competition for the IMDO, the International Medicine and Disease Olympiad. The first USMDO was held in 2022 and qualified 8 students for the 2022 IMDO, almost all of whom won gold medals at the international competition. The fifth annual USMDO will take place in August of 2026.
The USMDO consists of one online exam that tests knowledge in the following three general areas of medicine-related Biology: 1) Cell Biology and Genetics, 2) Human Physiology, 3) Human Disease. The exam contains 160 multiple-choice questions, to be finished within 2 hours. Participants have a 12-hour exam period to login and begin taking the exam. This ensures that all US students who wish to compete in the USMDO can participate, regardless of their location in the world.
​
The USMDO is open to all US high school students interested in human biology, medicine, health, and disease. It is a great competition for those students who are considering careers in biomedical sciences and healthcare.​​​
