The National High School Mock Trial Championship is an American nationwide competition of high school mock trial teams. Hundreds, and even thousands of teams participate in district, regional, and state tournaments to select one champion team to represent each of the 50 states. The competition debuted in 1984 in Des Moines, Iowa, with teams representing Illinois, Iowa, Minnesota, Nebraska and Wisconsin.[1]
Iowa has been the most successful state in the competition, setting a record in 2023 with its fifth national championship. Georgia has earned the title four times, while Washington State and Tennessee have each won the national championship three times. California, New Jersey, South Carolina, Indiana, New Mexico, and Arizona have all won twice.
