Regionals

In Ohio, regional tournaments are qualifying competitions for teams wishing to advance to the state or national level. Each regional tournament abides by the official Science Olympiad rules.

Some regional tournaments allow two teams per school to participate, while others only allow a second team to participate pending space availability. Refunds will not be issued to teams unable to participate in a regional tournament due to space or scheduling conflicts. Teams are encouraged if at all possible to participate in an invitational held on the same day. Regional tournament directors will communicate to all teams assigned to their region (including waitlisted), confirming or denying accommodation.

Organizing and conducting a regional tournament requires significant resources. Therefore, depending on the funding available in your region, it may be necessary for your team to pay an additional regional tournament fee. You may find information about your specific regional tournament and any other fees by contacting the regional tournament director.


* Please Note: All second teams are waitlisted in Ohio until tournament directors can determine space accommodations based on team registrations.
