International Linguistics Olympiad

International Linguistics Olympiad (IOL) is the largest international linguistics competition and is one of thirteen International Science Olympiads. It started in 2003 and is now held annually, traditionally between late July and mid-August.

History
The first linguistic olympiad for secondary school students was organized in 1965 ...

Eligibility
Participating teams will consist of no more than four contestants and will be accompanied by a team leader.

The contestants must be less than 20 years old on the first day of the competition, and must be pre-university students. Eligibility may be extended to students attending an affiliated school in another country or registered as home educated. Citizens living in another country may be eligible for inclusion in the team, at the discretion of the National Organizers. (However, the norm is that contestants will represent the country where they live/are educated.)

Contestants should be chosen on the basis of participation in a country-wide contest in linguistics or a related field held by a recognized national organization (including that of another country), open to any resident of the country obtaining their education in the country.This contest should be held in a language of education in that country and should not exclude from participation any students who would otherwise be eligible. It will therefore normally be held in (one of) the official language(s) of the country. Contestants who are eligible for multiple qualifying contests may compete in only one such competition.
