The International Physics Olympiad (IPhO) is an annual physics competition for high school students. It is one of the International Science Olympiads. The first IPhO was held in Warsaw, Poland in 1967.

Each national delegation is made up of at most five student competitors plus two leaders, selected on a national level. Observers may also accompany a national team. The students compete as individuals, and must sit for intensive theoretical and laboratory examinations. For their efforts the students can be awarded gold, silver, or bronze medals or an honourable mention.

The theoretical examination lasts 5 hours and consists of three questions. Usually these questions involve more than one part. The practical examination may consist of one laboratory examination of five hours, or two, which together take up the full five hours.

In 1978 and 1980, the IPhO was not organized. This was due to the accession of the Western countries. The first western country to participate was France.[1] At first, the few Western countries participating declined to accept the principle that the IPhO be organized every second year in a Western and Eastern bloc country. Thus the Eastern block countries declined from organising the 1978 and 1980 olympiads. From 1982 onwards, the yearly competition was resumed as there were enough participating Western countries to share the load. At present, the venue of the Olympiad is decided for years ahead. After accession into IPhO, every country must notify the others within three years about its willingness to host the IPhO. After this, the country is placed on a waiting list which as of 2006 stretches well into the 2050s. The failure to organize the IPhO on turn will lead to temporary expulsion from the IPhO. This happened to France in 1986.

Structure of the competition[edit]

Distribution of medals[edit]

The minimal scores required for Olympiad medals and honourable mentions are chosen by the organizers according to the following rules: A gold medal should be awarded to the top 6% of the participants. A silver medal or better should be awarded to the top 25%. A bronze medal or better should be awarded to the top 50%. An honourable mention or better should be awarded to the top 67%. All other participants receive certificates of participation. The participant with the highest score (absolute winner) receives a special prize, in addition to a gold medal.[2]
