North American Computational Linguistics Olympiad at the University of Florida

The North American Computational Linguistics Olympiad (NACLO) is a national contest for high school (and middle schools) students. Contestants compete to solve creative and challenging linguistics problems drawn from a variety of languages. Though no prior knowledge of particular languages or of linguistics is required, strong logic, reasoning, and problem solving skills are useful.

The first round of NACLO competition is held locally at various locations in the U.S. and Canada. Students who score well advance to a second invitational round of competition in March. Winners of NACLO are eligible to compete on the US National Team in the International Linguistics Olympiad, one of thirteen international Olympiads for secondary school students. The 2020 international competition will take place July 20-24, 2020 in Ventspils, Latvia.


For more information, see the national NACLO site and the International Linguistics Olympiad site.


Registration is available here. Participation is free. Registration for NACLO 2020 opens in Fall 2019 and ends one week before the competition date. Onsite registration is available.
