Mathematics and Computing Contests

Mathematics and computing contests are a fun way for students to grow their problem-solving skills, build confidence and get creative with math and computer science.

Who Writes Our Contests?

Our contests are written by students around the world. Designed by teams of expert educators for Grades 5 to 12, CEMC contests are a great fit for students with a range of abilities—from learners who want to explore math and computer science and develop their confidence, to advanced students who want to stretch their limits.

How to Get Involved


If you’re a student who wants to get involved, the first step is to talk to a math or computer science teacher at your school. It’s not possible for students to individually register for a contest — all students must participate through their school.


If your school hasn’t participated in a CEMC contest in the past, you’ll need to apply for a CEMC school account before you can order contests for your students. Follow the links below for everything you’ll need to know to get started:

Already have a CEMC school account? Visit our Contest Supervisor Portal to order contests, access results and certificates, download contest instructions and more.
