Each participating country sends 1-2 teams of four contestants each. The methods of choosing these contestants and composing the teams differ from country to country; in most cases a country’s contestants are chosen from the winners of their national Linguistics Olympiad. Check here to find out how contestants are chosen in your country.
What do I need to do to prepare?
No prior knowledge is necessary to compete at the IOL: every problem is self-contained.
The best preparation possible is to attempt as many past problems as you can. Start with the samples if you’re new to IOL problems and when you’re ready take a stab at our past problems. If you’ve done all those and can’t get enough, the national olympiads below also keep archives of past problems.
What if my country doesn’t participate?

Note that organizations wishing to set up a national contest must be not-for-profit. No association which aims to run its national competition for financial gain will be accepted.
