Contests for Students

OCTM Mathematics Tournament (local sites)

The OCTM State Mathematics Tournament is an annual mathematics competition open to any students taking high school mathematics courses.  The format and time frame will be changing in 2021.  The tournament will take place on a school day during the fall semester (to be determined), and students will participate at their own schools.  More information will be available in early 2021. 

The tournament also has its own website. To open a new window displaying the tournament site, click on:

The 46th Annual ARML Competition (national) was canceled due to COVID-19.  ARML is normally held around June 1.

The American Regions Mathematics League sponsors an independent mathematics competition, not connected directly with OCTM.  OCTM does support the Ohio team (top scorers from OHMIO -- see above) as it travels to ARML each year, and the Ohio coaches are involved with OHMIO.  To learn more about ARML, visit their website here. If any questions should arise, please contact Michael Curry from ARML at
