Due to the ongoing pandemic, SDSU will not be able to host this year. We're very sorry for this, and hope to see you again in 2022!

What is NACLO?

The North American Computational Linguistics Open Competition is a contest in which high school students solve linguistic puzzles. In solving these puzzles, 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.

When is NACLO?

The NACLO open round will be held from 9:00am to 12:00pm on January 23, 2020.  The online registration deadline is January 23, 2020.  The top 100 participants nationwide in the open round will be asked back for the invitational round to be held March 5, 2020.  Both events will be held at San Diego State University – watch this site for more details about the logistics.
