Invitationals | Science Olympiad

Science Olympiad Invitational Tournaments allow Science Olympiad teams to participate in tournaments that do not impact regional or state advancement or rankings, but are often used as tryouts for team members and as preparation for teams that compete in regional, state or national tournaments. Across the country, many campuses and schools host these events to give teams a chance to perfect their devices and get a feel for the difficulty level of tests and labs.

Science Olympiad Invitational Tournament Requirements

New for the 2026–2027 Season: The Science Olympiad Executive Board has implemented a policy limiting any educational institution to hosting no more than two (2) Invitational Tournaments per season. Requests exceeding this limit will not be approved.

Science Olympiad Invitational Tournaments are optional events that typically charge a separate registration fee. To participate, teams must be current members of both their state and national Science Olympiad programs.

To host any Science Olympiad Tournament, Tournament Directors must submit the annual Tournament Director Form and receive approval from their State Director and the Science Olympiad National Office.

Must be one of the following:

A State Chapter (Regional or State Tournaments)
An officially recognized Science Olympiad Alumni Chapter
A school district with a current registered Science Olympiad team and approval from the appropriate school administrator.

Please contact your State Director for the Tournament Director Form password. If requested, Invitational Tournaments will be posted on our website. Only in-person tournaments held at a single location are eligible for Science Olympiad's primary insurance coverage. Please review the Science Olympiad Copyright Statement regarding the use of Science Olympiad Rules and procedures at sanctioned tournaments.

Food Safety Notice: Tournament organizers may only provide food through licensed food vendors. Participants, volunteers, and teams may bring their own food for personal consumption.
