The Ohio Academic Decathlon is a statewide non-profit organization that promotes an educational experience providing a format in which teams of nine high school students compete in academic events. All Ohio public and private high schools are eligible to compete. The Academic Decathlon embodies a partnership of business, foundations and individuals in cooperation with the education community and county offices of education.

The makeup of each of the nine member teams must include three A students, three B students, and three C or below students.

Academic Decathletes take 30 minute multiple choice tests in the subjects of Economics, Art, Music, Language and Literature, Mathematics, Science, and Social Science. In addition, each team member gives a planned 4 minute Speech and a 2 minute impromptu Speech, sits through a 7 minute Interview, and has 50 minutes to write an Essay. The only event open to the public is the Super Quiz Oral Relay which deals with either the Science or Social Science topic.

The Ohio Academic Decathlon season involves 4 rounds of competition. Winning teams advance through the local, regional, and state levels of competition. The state champions compete at the national finals in late April.
