Oregon Invitational Math Tournament

OIMT is an opportunity for the best and the brightest high school mathematics students in Oregon to come together for a day of competition, learning, and fun!

The 2026 OIMT will hosted by the Oregon State University Department of Mathematics on Saturday, May 16, 2026. Professor Elizabeth Carlson, Instructor Brian Moore, and Instructor Derek Eby are serving as local coordinators. For additional information or questions, please contact Elizabeth Carlson.

Contest Categories

The OIMT offers 4 different exams:

Algebra 2,
Geometry,
Open I (advanced, but no calculus questions), and
Open II (advanced and includes calculus questions).

As in recent years, there will be a group exam separate from the main exams. This exam will test your logic and collaboration skills (and should be fun!). Students who are qualified for any of the previous four exams are welcome to sign up for this exam.

Regional Competitions

Contacts for regional competitions to compete in order to qualify for the OIMT can be found here.

Thank you

The Oregon Council of Teachers of Mathematics support the OIMT by providing medals for top finishers in each of the contest categories.

How are students invited?

Students are invited to OIMT based on their performance at the regional contests held at other higher education institutions across the state. The top 12% in each category from each regional site will be invited (rounded up). An invitation will be sent to their high school once names are provided by the regional site contacts. The regional contests normally occur between February and April.

Students may also be invited due to exceptional scores on the AMC-10 and AMC-12 exams (American Mathematics Competition). The qualifying AMC score for OIMT is 80 for both the AMC-10 and AMC-12 exams. If you have a qualifying AMC score please contact Elizabeth Carlson.

Can students below 9th grade participate?

Students below 9th grade are generally not eligible to participate in OIMT (there are other competitions, such as MATHCOUNTS, that are especially for middle school students). We make an exception if the student is taking a math class at a high school (this is different than taking a high school level class at a middle school).
