2025 Dennis Papesh Memorial, Centerville Invitational

January 24, 2026

Hadley E. Watts Middle School

7056 McEwen Rd

Washington Township, OH 45459

We will host B-Division, in-person format only. Each registered team is required to supervise, or assist with supervising, one event. The team registration form will allow coaches to select up to five of their most preferred event choices.  Please submit a separate registration for each team you are bringing and name them in a manner that easily allows the tournament staff to differentiate them (e.g., Centerville-A, Centerville-B, Centerville-Gold, Centerville-Black, etc.).

We are limiting the tournament to B-Division teams. Medals will be awarded to the 1st, 2nd, and 3rd place finishers for each event; ribbons will be awarded for finishes in 4th through 8th positions. Team trophies will be awarded for the top eight places overall. Schools with multiple teams may only earn a single overall trophy. 

Every participating team must be registered with Ohio Science Olympiad, or their home state's organization, if outside of Ohio, to participate in the Centerville Invitational. Tournament registration will begin on September 10, 2025; a registration link will be provided on this page. The team registration fee is $100 per team.
