Invitational Tournaments

Invitational tournaments are organized across Michigan, typically under the leadership of an individual team.  Teams which attend 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 Michigan invitational tournaments in Divisions B and C must be registered with the National Science Olympiad organization.  If you are interested in hosting an invitational tournament, please contact the State Director to receive further information.

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 your school will compete, you must have an Alternate team.  Registration is important to ensure that all students who participate are covered by liability insurance which Science Olympiad provides.  These registration requirements are actively monitored, and Michigan Science Olympiad reserves the right to take disciplinary action against teams which violate this policy.

Teams are also welcome to attend invitationals anywhere in the country. See the National list of invitationals for more information.
