The United States Academic Decathlon® is a ten-event scholastic competition for teams of high school students. Each high school enters a team of nine students: 3 Honor students (3.80 – 4.00 GPA), 3 Scholastic students (3.20 – 3.799 GPA), and 3 Varsity students (0.00 – 3.199 GPA). The theme of study changes each year.
