FAQs for Teachers / Organizers – CJMC 2023


  • Students in kindergarten all the way up to grade 8 can write the CJMC (Grades K-8).
  • The questions are based on the math curriculum from grades 5 to 8.
  • Participating in nationally-recognized mathematics competitions is a fantastic item to add to their portfolios if they want to seek an entrance scholarship in university.
  • Gain new experience in problem solving that lets them measure themselves against some of Canada’s keenest math students.
  • We issue official certificates to all competitors and recognize the top achievers publicly on our web site. Gift cards may be awarded to those who achieve perfect scores on the CJMC.
  • Teachers/Organizers hold the competition at their own school.
  • Alternatively, some of our partnered universities across Canada host "Open Writing Centres" to host a limited amount of students who are interested in writing the CJMC exam. 
  • For schools in Canada, or anywhere in the time zones covering North/South America, it’s on Thursday November 16th. Elsewhere in the world, it is to be held Friday, November 17th.
  • We let the proctor/teacher decide what actual start time works best for that date.
  • 90 minutes; 15 multiple-choice questions.
  • Paper or online.
  • For paper exams, we offer shipped or PDF. Shipped exams are printed by CMS then shipped to schools. PDF exams are cheaper, and we supply PDF documents of the exam for teachers/organizers to print.
  • For online exams, we use Webtest, an online testing platform. Teachers are given exam codes to provide to students on exam day, students log into webtest using a computer and write the exam online.
  • The set of questions is the same for all students of all grades.  All questions are multiple-choice.  There are:
    • Five introductory questions, worth 4 points each;
    • Five intermediate questions, worth 5 points each; and
    • Five advanced questions, worth 7 points each.
  • Maximum score: 80 points.
  • To discourage guessing, we award 1 point for any question left unanswered.
  • It’s multiple choice, so students don’t need to “show their work” for anything, but should be given scrap paper.
  • No.
  • When the students leave you with their answer sheets, you simply scan them and upload them as a PDF to our site within the Competitions Portal and we process and mark them.
  • If writing the exam online using Webtest, students submit their exams online and we collect them for marking.
  • No, we also offer it in French.  
  • We just ask you which students need which language.
  • Teachers (or organizers).
  • Minimal student information is indeed required, but students engage with the competition through the teacher, so the teacher provides a list of competitor names, etc.
  • It is important to fill in student information within the portal prior to ordering exams, as the exams will be tailored to have student information on them.

Schools and Other Organizations

  • Yes. We have an International Division (see our Prizes and Awards page) that your students could compete in.
  • Generally, we ask that schools that are in time zones outside North/South America write the competition the day after those in Canada write it.
  • In some countries, we also have International Partner organizations that help to coordinate students writing the competition in those countries.  You are welcome to click their links on our International Competition Partner page for contact information or more details.
  • Yes. The CJMC is a competition that is open to any student in grades K-8 with an interest in and grasp of mathematics.
  • However, in order for the students to write the competition as official competitors, there are eligibility requirements.  In particular, the exams and the proctoring must be handled by a Qualified Proctor, who has a current, provincially-recognized teaching certificate and is not family-related to any of the students.
  • An organization such as one of these would normally either write the exam unofficially, or they would contact a suitable teacher to agree to be the person to receive and/or print the materials, invigilate the students, and send their work back to us for official processing and marking.  All such nominated proctors need to be vetted by the CMS to ensure the integrity of the competition. The organizer would still be the one with access to the orders and all the results, of course.
  • More information about this is on our Eligibility page.

Registering (Ordering)

  • Typically one week before the competition date for online or PDF exams. This year the registration deadline is November 10th for online or PDF exams.
  • Typically two weeks before the competition date for printed/shipped exams. This year the registration deadline is November 3rd for printed/shipped exams.
  • Please see the information on our competition’s home page, under Rates and Delivery Methods.
  • Please see our Inclusion Initiative page.  In short, it is a small number of free registrations we offer to increase the rates of participation of traditionally under-represented groups.
  • This only applies to schools in Canada that we have assessed as Official.
  • Schools with students who qualify must email us before they place their orders. Tell us the number of students that you are applying to have covered by the Initiative and the number of exams overall that you intend to order. We will then email you specialized instructions for how to place your order such that the amount due is reduced accordingly. Note that there is a maximum of 5 free exams per school.
  • Note that the CMS does not ask for the actual identities of the students designated in this way.
  • When registration is open, you will see a big Register Now button on the competition’s Home Page. This will take you to the Competitions Portal.
  1. Create a new account  (if you don’t already have one on our new Portal).  Choose “Create Account” and provide your email address.  Then find a verification email message we send to you in the following few minutes. Click the link in the email message and then provide your name and set your password.  Next, choose “School/Organization” as your account type (rather than “Student”).  Last, provide the name and address of your school.
  2. Register for CJMC. It will be listed as one of the choices of competitions open for registration.  Select the number of exams you want to order and confirm it.  This creates an unpaid order on our system.
  3. Payment.  If you can pay online using a credit card or Paypal account, you are encouraged to do that.  Some schools still require hardcopy invoices and need to mail us paper cheques.  This is also acceptable, as long as you can meet the payment deadline.  You can print the invoice for any unpaid order you make.
  4. Receipt.  Once payment is made, a receipt is available on your Portal.
  5. Identify your students.  This is new since 2023. Use the Student Roster function in your Portal to tell us who your students are.  All competition papers come prepared with pre-printed student information on them.  The information we need is fairly minimal and should likely be close.  This is an important new addition, please be sure to have this done before the registration deadline.
  • Please refer to the Eligibility page.
  • If you just newly created your Portal account, we need a 1-2 business days to make sure your information isn’t from a spam bot or someone trying to get advance access to the questions for cheating. When we do our assessment, we email you to notify you of the result.
  • Even if after assessment, your organization is still flagged as Unofficial, you can make special arrangements with a qualified proctor so that your students can indeed participate as Official Competitors.
  • Note that this doesn’t prevent you from ordering exams and doesn’t affect the prices.
  • You just add an extra order.  The minimum order size is waived in this situation (if the minimum order size has already been paid for).
  • Up until the applicable registration deadline: Yes, with restrictions. You can’t reduce your total ordered exams below the minimum order size. We also charge a 10% administration fee. The rest we will refund to you.  We may end up canceling your original order and creating a new (paid) order in its place with the revised size.
  • After the applicable registration deadline: No, because the exams have already been generated. However, if you find someone else who wants to write the competition in place of the original student, you can do that.  Just change the information in your Student Roster and, if needed, cross out the old student information on the Student Answer Sheet and write in the new student’s information.  It would also help if you emailed us to alert us to this change.

Student Roster

  • Yes this is a new requirement since 2023.
  • The Student Answer Sheets come pre-printed now with the student information on them.  You just give each sheet to the designated student.  We use this to expedite the marking and processing.
  • The information we need for each student is kept fairly minimal:
    • First and Last Name
    • Grade (based on the North American K-12 system, plus Cégep for Quebec)
    • Full time student (yes/no)
    • School name (this defaults to your own school name and appears on the certificate – it is here to allow for the situation where a guest student from another school is joining your group just for the competition).
    • Gender Identity (optional)
  • It’s optional. Teachers are welcome to select “Prefer not to say”.
  • The reason is twofold. First, we are involved in some invitational competitions, for example the European Girls Mathematical Olympiad (EGMO) which restricts participation to female-identifying students. When we are considering who to invite for training these students and sending a Canadian team to Europe, we need to include that restriction. Second, we want to encourage greater participation in our competitions from girls and want to track how well we are doing.
  • If the student does very well and earns one of the Gold/Silver/Bronze or Honourable Mention awards in one of our divisions (see the Prizes and Awards page), then we only identify the student by name and school on our website.
  • Unless someone scores “perfect”, we don’t mention their actual score publicly.  Of course, the teacher has access to all the scores of their own students.


  • Online payment is preferred. We use Paypal to handle our online payments. If you have a Paypal account, you can certainly use it, but you do not require one if all you want to do is process your credit card for our exams.
  • Paper cheques are still accepted. Some schools still require the use of traditional invoices and send cheques to us by mail. This is also acceptable, but it remains the responsibility of the school to get us the payment by the due date.
  • Friday, November 10th, 2023.

The CMS reserves the right to cancel any order which remains unpaid after the payment deadline. If you anticipate your payment to be late, please contact us at

  • Log into your portal and choose the competition involved.  
  • Once you've selected the competition, you will see a link on the right-hand side for each of your orders (if you have more than one).  If you choose an order that is unpaid, you will see the invoice and you can print it if you wish.
  • Once payment is received, we update your portal order history and status.
    We also send you an email to notify you of this.
  • If you have paid for an order and want to cancel it, you need to contact us.
  • Until the applicable registration deadline, we issue refunds less a 10% administrative fee.  After this date, we do not issue refunds.
  • If your order isn’t marked Paid, you can cancel it yourself using your Portal.

Materials and Proctoring

  • If you ordered Printed and Shipped exams, then we pre-print them and courier them to you and you should receive them by Tuesday prior to the competition.
  • If you ordered PDF or online exams, we will put them in your portal for you on Wednesday to download (PDF) or view the Webtest code (online).
  • In special cases where the organization is using a specially-arranged proctor, we send the PDF materials directly to the proctor via email rather than posting them to the Portal.
  • If you do not have what you expect by early that Tuesday, or Wednesday for PDF orders, please email us or phone us (613-733-2662) for help.


  1. Immediately after the students leave, make sure you have all your students’ answer sheets and count them.
  2. Use a scanner or multifunction copier to scan these sheets into a PDF (or more than one PDF if necessary).
    Open the PDF file(s) on your computer and make sure all the pages are there and none are blurred or otherwise improper.  Rescan pages you need to rescan, if any.
  3. Now log into your Portal account and select the competition.  You will find a button that allows you to upload your student scan PDF file(s) there.  If you are a specially-arranged proctor, you can email it to us.
  4. Remember to file a “Proctor’s Report” through your Portal.  This is necessary in order to flag the students as official participants.  We need your confirmation that no cheating or suspicious behaviour occurred. If you are a specially-arranged proctor, you can scan and email your report to us.

Please keep your exam material in a safe place for two weeks in case we detect a problem with the upload


  1. Immediately after the students leave, make sure you have all your students’ booklets and count them to be sure.
  2. Insert them in a courier envelope (or another sturdy envelope) and attach the courier pre-paid waybill.  Do not include unused/blank exams.  It will have the address of one of our partner universities on it.
  3. Give this to your main school office by/before early Friday morning.  The courier is scheduled to come pick up the package sometime on Friday. 
  4. Please ensure the Proctor Declaration is in the envelope along with the exams to be shipped.

Note: if you are not located in Canada, you will need to courier the materials back to us at your expense.  The address to use will be in your Instructions.

       1. Submit through Webtest once the 1.5 hour competition is complete.

If you have technical or logistical problems, please email us.

  • Please collect the question booklets and scrap paper used to calculate answers from the students as they hand in their Answer Sheets.  Some schools, particularly overseas, may be writing the competition later in the day or the next day, so it is important to minimize the potential for cheating.  Anytime after Monday, they can be returned to the students, used for discussions or recycled.
  • Calculators, phones and other electronic devices are not permitted.

  • Dictionaries, if needed, can be used if the Proctor/Teacher monitors their use.

  • Non-electronics such as protractors and compasses are permitted.
  • Please allow this if you can.  

    1. Find the (otherwise unused) Student Answer Sheet for the missing student.  Cross out the student information on the sheet.  Write the name, and grade of the replacement student on the sheet and let the replacement student use that for the competition.

    2. Please email us to alert us which student you are replacing with which student, so we can adjust our files.
  • If you have any exams you ordered but didn’t give us the name of the student in your Student Roster, you can use these. 
  • They would typically have blanks for their names, but unique registered student numbers.  Cross out the student information on the sheet.  Write the name and grade of the student on the sheet and let the student use that for the competition.
  • Do not photocopy the student answer sheets - each one is coded for a particular student and you could end up with both the exams (the original and the photocopy) being disqualified.
  • If you did not order any extra exams, then you are limited to those you have.


  • We intend to release scores, results and certificates within about 7-10 days after the competition. 
  • When this happens, we will email you and you will be able to log into your Portal to see or print the detailed scores for your students, get their certificates, and learn which awards they may have earned. 
  • At that time, anyone can go to the competition main page to see the overall results both in Canada and Foreign divisions, breakdowns by grade, and by province or region.  There are no public results comparing schools to one another.
  • All students who write as Official Participants get certificates of one kind or another to add to their math portfolios, or to frame as they see fit. 
  • We create earned Award Certificates for those with high scores and quartile-based Certificates for those who didn’t earn specific awards.
  • All the certificates are accessed through the Competitions Portal.
  • We will correct any errors that may arise.  That said, it is possible some errors will be detected by you as well, so if this is the case, by all means email us about it.

Account System

  • Yes. It is new as of September 2023.
  • All schools/organizations need to create a new account on the new system.  It uses the email address you provide for logging in, rather than the school’s ID code.
  • Prior to 2023, we had an older system.  It’s still online so schools wanting to access their historical information still can.

    You may access the old portal here.
  • No.  Only the teachers (or organizers) have a Portal account.  They manage their students using their teacher account.
  • First please note that we have a new (2023) Portal system and it requires new accounts for all schools.
  • The new Portal system is based on the unique email addresses of the organizers/teachers.
  • There is a Forgotten Password link on the login page that will send an email verification code to you so you can reset your password.  It should arrive within a few minutes.  Check your Inbox and your Junk/Spam mailbox and click the link you find there.
  • If you are still struggling to get into what you are certain is your account, you can contact our office, but we will require extra steps to ensure your identity and it may require a few days to do this.
  • Please email the CMS office to change a school address. In your email, please include: your current school address, the new school address, your email address and your school ID.
  • To minimize the potential for cheating, we have to manually inspect and verify these changes.
  • This is possible, but we have to take steps to ensure this isn’t abused or used as a way to cheat. Please email us the details of your situation, including old and new address, your name and your school’s name.
  • Detail the situation in an email to us. 
  • If you have a contact at the old school who can “take over” the old school’s information (and possibly will be the competition coordinator there now that you’ve left), please include their name and email as well. 
  • Be sure to include a full mailing address for your new school as well. We may require extra steps to ensure all changes are properly authorized.
  • No. You just need one
  • Your portal will have all your history organized by competition and year.
  • The new Portal system doesn’t have the old years’ data on it, but the old system is still running.  You can access the old portal here.
  • Remember: Teachers log into the old portal using their old school ID codes and their old passwords.  
  • One cannot register for new competitions using the old system.
