Training Sessions

The Yale Department of Linguistics hosts training sessions to provide information about NACLO and to allow students to try out practice problems. The sessions will take place between 2:00pm and 4:00pm on the following Sundays: October 18, November 8, December 6, January 24. Because of COVID, these will be held on line via Zoom. If you plan to attend these sessions, please register. The link for the Zoom meetings will be made available to everyone who registers. If you have any questions about these training sessions, or about the NACLO contest at Yale, send email to Prof. Raffaella Zanuttini at yalenaclo@gmail.com.

Open Round Information

The open round of the NACLO competition will take place on Thursday, January 28, 2021. The competition runs from 10:00am until 1:00pm. Because of the COVID pandemic, we will not be able to host the competition at Yale this year. If your high school is hosting the competition, you may take it there. Alternatively, you can sign up to take it from home by registering for the “at home” site, one of the options available in the University sites category on the NACLO registration webpage. 

The competition is very challenging and is designed for high-school students. Middle-school students are welcome to participate as well, but we recommend this only for those middle-school students who are especially well-equipped to deal with this kind of academic challenge.

NACLO Registration

Thanks to the generous support of the sponsors, 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 Wednesday, January 15, 2021.
