Friday, January 10, 2020 – ROUND ONE will be available and features a 40-minute test with questions based on topics that address middle school mathematics skills and must be completed no later than Friday, February 14, 2020.

The question sheet is formatted for easy scoring. One copy of the question sheet and answer key is sent by email to middle school math teachers/test administrators who have registered online.

Test administrators will duplicate the test as needed. Test questions and answers are posted on the OSSM website after Round One concludes. We encourage teachers to use a convenient class period for students to participate in Round One.  A Certificate of Participation is available for all Round One students.

Individual students may compete if their local school does not. Parents will register the child and perform the duties of the test administrator.

Home-schooled students are also encouraged to participate.

Direct all ROUND ONE registration questions to Mr. Dan Vossen.


Practice Tests

Note – It is possible that a few practice test answer keys may still contain a few incorrect answers. Over the years, we have attempted to resolve these mistakes, but we may have missed a few. If you would like to contact an OSSM math professor about a particular test problem, please identify the exact test title, problem number and your answer to start the process. Send all inquiries to and he will forward them to an OSSM mathematics professor for a response.

Home-schooled students are also encouraged to participate.
