The Results

  • How do schools obtain the students’ participation and award certificates?
    When the final results are announced, teachers/organizers will be able to log in to their accounts to download and print participation certificates for all of their students.
    Awards certificates are only provided for official participants who achieve a high ranking, which are available for teachers/organizers to download and print. For students in Canada, award certificate plaques or portfolios are mailed to their schools.
  • How do I get my score?
    Teachers can access all their students' scores online using their school account once marking is complete. Individual scores are not shown publicly for privacy reasons.

    If one or more students' scores are unavailable, please contact the CMS office by email at

  • What is an 'official paper'?
    To be considered official and thereby qualify for awards or prizes, participants and schools must meet the requirements as described on our Eligibility page.
  • Will I get a certificate?
    When the final results are announced, teachers/organizers will be able to log into their accounts to download and print the certificates for all students. For those students who have earned award(s), the certificate lists all the awards the student earned. For students who did not earn specific awards, the certificate is based on which quartile their scores fall into:
    1st quartile = Performance with Distinction
    2nd quartile = Performance with Honours
    3rd or 4th quartile = Certificate of Participation
  • Will I get a plaque?

    The CMS no longer issues student plaques. Students now receive a student portfolio (certificate in a commemorative folder). All students who earn a Gold, Silver or Bronze in non-grade specific categories at the regional or provincial level are eligible to receive a portfolio. All students who receive a Gold, Silver, Bronze or Honourable Mention on any of the Canada lists including grade-specific lists will also receive a portfolio.

    School plaques are only given to schools where at least one student is being sent a student portfolio.

  • Will I receive a prize?

    Anyone writing the COMC in Canada is also eligible for random draw participation prizes. Approximately 160 prizes will be distributed to participants nationally.
