The North American Computational Linguistics Olympiad (NACLO) is a contest for U.S. and Canadian high school and middle school students in which contestants compete by solving compelling and creative puzzles in linguistics and computational linguistics. Winners of NACLO are eligible to compete in the International Linguistics Olympiad (IOL), one of twelve international high school science Olympiads.  No prior knowledge of linguistics or second languages is necessary.

The NACLO consists of two rounds. The first round is open to all interested students. Top scorers in the first round are invited to compete in the second round. Visit the NACLO site for sample problems.

Students who would like to participate in the first round of the NACLO in Austin must register through the NACLO website.  Select "The University of Texas at Austin" as your testing location (even though the first round will actually be held at LBJ High School). There is no participation fee. Registered students will receive directions and other important information before the day of the contest.

Please contact us if you have questions about the NACLO in Austin.
