HI-Q is a team-based, quiz bowl style competition. Two teams of four go head to head in three ten-minute sessions in which questions are asked to each team. A normal or toss-up question is asked to both teams. The teams then have five seconds for anyone on either team to buzz in and answer the question. If answered correctly, the team is awarded a harder, bonus question that they are given fifteen seconds to answer as a group, without the other tam getting a chance to answer. Every year, there is a district competition; the winning team then goes to regionals along with the team who has the best record of the season.

Players enjoy the intellectual stimulation of the matches, the friendships formed by the competition (both within their school and of the other teams), and of course, the free food that is offered at the end of each match.
