WSO Division B Event Categories 2024-2025

WSO Division C Event Categories 2024-2025

*Wisconsin additional or substituted events.

NOTE for the State Tournament Only: Each Division B and C Team must balance their chosen 23 events from the 5 Science Olympiad categories. Each Team must choose a minimum of 3 events from each category to reach a total of 23 events. 

A Team may only enter only 23 of these events for Team score; Team score determines a State Champion. Additional events beyond the 23 may be audited for no Team score.

Important... This event format has several advantages. It enables a wider variety of events to be offered in hopes of catching the interest of more students. It gives the coaches a better chance of matching the students individual strengths and talents with those events. It helps to assure that one or two Teams will not dominate all events. It encourages Teams to become more diversified in their preparations. It opens the possibility for Teams to audit events and therefore involve more students.  By requiring Teams to balance their choices within the categories they will more adequately satisfy the Science Educations Standards.

Wisconsin Science Olympiad Div C State Competition does have a system where events beyond the chosen 23 can be audited. The Audit Events do permit additional students beyond the 15 to participate (including seniors) and compete at the State Competition. Auditing an event gives a Team a chance to not only involve more students, it gives them a chance to gain knowledge about the 5 events they have not chosen for Team score. This experience is invaluable as the Teams prepare to advance to the National Tournament.
