Invitational Tournaments are optional competitions that give teams a chance to practice their skills, tinker with their devices, and experience the difficulty level of tests and labs in a tournament setting. Participation does not impact team regional or state advancement.
Invitational tournaments require a separate registration fee, to be collected by the invitational tournament director. Invitationals use the official Science Olympiad rules and are usually hosted by local middle and high school teams. Some tournaments may limit participation strictly to their region, while others have "open" registration where anyone (including out-of-state teams) can participate.
All teams participating in any Invitational Tournament must be a registered member of a state Science Olympiad program.
Please note: Ohio does not sell its invitational tests or accept offers of registration payment for teams not participating in the actual tournament.

2025-2026 Battle of the States
Format: Satellite open to teams in Illinois, Indiana, Minnesota, Michigan, Ohio, Pennsylvania, and Wisconsin
Date: Events continue through December, January, and February
Cost: $30, teams in first two years of Science Olympiad participate for free
Each event will be open for two weeks so teams can choose the time that best works for them to either take the timed test or make the required submissions. The twist is, the tournament will not be ranking teams overall - teams will compete for their state! After each event, the top teams from each state will have their scores combined to see which state comes out on top. Feel free to participate in as many or as few events as your team would like, since the tournament will not be ranking teams overall. Registration will remain open throughout the tournament as long as there is room for more teams, so your team can still register even if you miss the early sessions.
