Competition Tiers
2024 Rules


Regional competitions serve to reduce the amount of teams competing at the state level.


At the state competition, the top teams in each region in a given state compete with each other. The state competition decides the team(s) that advance to the National Tournament. 


The final contest in Science Olympiad is the best teams from across the country competing against each other. The competition is significantly harder than most state and regional competitions. Prizes and scholarships are awarded to the top scorers in each event. The National Tournament is typically held on a university campus, with teams either flying or driving in.
