North American Computational Linguistics Open Competition (at THE university of south florida)

The North American Computational Linguistics Open Competition (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.
