NACLO 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. 

Each January thousands of middle and high school students across North America participate in NACLO, with the top-performing participants moving forward to the invitational and then international competitions. 

Participation in NACLO is free. Students who are interested in taking part will however need to register to participate in the competition at the NACLO registration site. Registrations will be accepted up until January 24, 2022.

The first (Open) round of the contest will take place on Thursday, January 27, 2022, from 10:00 am to 1:00 pm. Students who perform well in the Open round will be invited to take part in the second (Invitational) round to be held on March 17, 2022, from 9:00 am to 1:00 pm. The top students in the invitational round from across North America will have a chance to participate in the International Linguistics Open competition in the summer.
