Academic Challenge is a game show-style television program held by several universities throughout the United States. Each university hosts a group of regional teams (usually 8 or 16 teams) in a single-elimination tournament. The winner of each regional tournament receives an expenses-paid trip to the national tournament held later that year (usually in Washington, D.C.). Each team comprises up to six players, of which four play at any time, with the other players rotating in between rounds.
