, looking at convention participants The NJCL hosts a week-long national convention annually at a college campus in late July or early August, where 1200–1500 students compete in academic tests, graphic and creative arts competitions, and meet many classics students from around the country. Other components of the convention in which students may participate include Certamen, a quizbowl-like trivia competition, seminars commonly known as Colloquia, and Ludi (literally "games"—various athletic and recreational events). Students may also campaign for public offices within the NJCL, including President, Treasurer, and Historian. Starting regularly in 1972, every convention is given a motto/theme from Latin poetry or literature. A theme for the following year's convention is chosen by the incoming president each year.
