Illinois

History
The Science Olympiad started from the endeavors of Gerard Putz and Jack Cairns, who thought that science education could benefit from a multi-school science competition. It has grown to be a nationwide competition with 48 states and has also raised interest in countries such as Canada and Japan.

The annual Illinois state competition is held at the UIUC. There is a system of divisions for the state tournament - division A and AA, AA being more competitive. Teams are placed in divisions based on the competitiveness of their regional competition and also their placing at the previous year's state competition. This system of divisions theoretically allows teams who aren't as financially supported to medal and place higher than they would if placed against exceptionally competitive teams that are gunning to go to Nationals.

Past State Champions
This is a record of the past state champions and runners-up, and their respective places at the national competition, if applicable. Scores at the state competition may be shown in parentheses.


 * 1: Science and Arts Academy was originally placed at 18th. However, after a scoring error in Water Quality was discovered, they were awarded 14th place. There was no tiebreaker with Shady Side Academy, and both were awarded 14th.
