Are you interested in language(s)? Do you enjoy solving puzzles?

Are you a high school student (8th-12th grade) in the Champaign-Urbana area or Central Illinois?

The North American Computational Linguistics Olympiad (NACLO) is an international contest in which high-school students solve linguistic puzzles. In solving the problems, students learn about the diversity and consistency of language, while exercising logic skills. No prior knowledge of linguistics or second languages is necessary. Professionals in linguistics, computational linguistics and language technologies use dozens of the world's languages to create engaging problems that represent cutting edge issues in their fields. The competition has attracted top students to study and work in those same fields. This is a fantastic opportunity for young people to experience a taste of natural-language processing in the 21st century.
