NACLO at Princeton

The North American Computational Linguistics Open Competition is a contest in which high-school students solve linguistics puzzles, roughly parallel to the USAMO/USAPhO/USNCO/USACO for math, physics, chemistry, and computer science. 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. The winners of the Invitational Round are eligible to represent North America at the International Linguistics Olympiad.

We are pleased to host a local site of the 2020 NACLO at Princeton University. Any high school or middle school student is invited to participate in the Open Round. The best performing students on the Open Round will be notified in early March that they have qualified for the Invitational Round. There will also be a practice session on Saturday, January 11, from 2-3:30 PM in Green Hall 1-S-4A. For more information, please contact Professor Christiane Fellbaum at or Eve Fleisig at

The Open Round will be held at Princeton University from 10 to 1 on January 23, 2020, in Lewis Library 120. Please arrive 15 minutes before the start of the exam to fill out paper work, as we will start the exam immediately at the start time. Parking is available in lots 21 and 23.
