Each year, the OJCL hosts a convention in Columbus which brings together over 800 students, teachers, and parents from across the state of Ohio to celebrate the study of Latin. There are a variety of competitive activities at the convention: academic tests, art contests, certamen, and creative performances (in both English and Latin). In addition, the convention offers a number of social activities, including a dance, a toga banquet, and OJCL’s Got Talent! State Convention is also an opportunity for students to run for the OJCL Executive Board. Delegations compete in various contests to win prizes and recognition in Overall and Per Capita.
