The North American Computational Linguistics Open competition is a contest in which high-school students solve linguistic problems. In solving these 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 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. It is truly an opportunity for young people to experience a taste of natural-language processing in the 21st century.

The North American Computational Linguistics Olympiad (NACLO) Open Round will be hosted at Fort Hays State University on January 26th, 2023. You can read more about the competition and find practice problems at NACLO is open to middle school and high school students, not university students.
