NACLO 2014 at the University of Washington

The North American Computational Linguistics Olympiad (NACLO)

NACLO is an international contest in which middle school and high school students solve linguistics puzzles. No prior knowledge of linguistics or languages in necessary to solve the problems - just logic skills.
