Invitational Tournaments
About Invitationals
Invitational tournaments are independently organized events, often hosted by an individual team. Teams attending these tournaments may be expected to contribute by being responsible for running an individual competitive event. Attending teams should expect to pay a registration fee.
All teams which compete at these tournaments must be registered with Michigan Science Olympiad, and have paid their annual registration fee, including Alternate teams. If more than 15 students from a school will compete, the school must have an Alternate team.
If you are interested in hosting an invitational, contact the State Director to receive further information. Invitational tournaments in Divisions B and C must be registered with the National Science Olympiad organization.
Teams may attend invitationals anywhere in the country. See the National list of invitationals for more information.
If you have information for an invitational in Michigan, or of interest to Michigan teams, that is not yet listed, please contact us with the information to share.
