The United States Academic Decathlon (USAD) is an American academic competition for high school students. The United States Academic Decathlon National Championship, first held in 1982, pits winners at the state level against each other for a national title. The Academic Decathlon consists of 10 events: art, economics, essay, interview, language and literature, math, music, science, social science, and speech. The Super Quiz replaces one of the seven objective events; since 2003, it has alternated between replacing science and social science. The Academic Decathlon requires participation from students of all levels of academic ability; teams generally consist of nine members, who are divided into three divisions based on grade point average: Honors, Scholastic, and Varsity. Though teams consist of nine members, only the top two individuals from each category are counted in the final team score. Each student has the possibility of scoring up to 10,000 points, for a combined team score of 60,000.
