International Mathematical Olympiad
Supported by Google
The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition for High School students and is held annually in a different country. The first IMO was held in 1959 in Romania, with 7 countries participating. It has gradually expanded to over 100 countries from 5 continents. The IMO Board ensures that the competition takes place each year and that each host country observes the regulations and traditions of the IMO.
The IMO Foundation is a charity which supports the IMO. The IMO Foundation website is the public face of the IMO. This is a particularly valuable resource for people who are not necessarily mathematical specialists, but who want to understand the International Mathematical Olympiad.
Data is held at IMO-official in compliance with EU data protection legislation. If a participant wishes to become anonymous (neither photo nor name on public display), then contact the IMO secretary with a request. We will comply with bona fide requests expeditiously.
