CCC 2027: Arrange Your School Entry and Switch Off AI Tools

Ask a math or computer science teacher whether your school can order and host the Canadian Computing Competition (CCC). Coding happens online, but you must sit individually at the ordering school under in‑person supervision for the entire contest.

A student grader account is not a contest entry. Confirm the school order, teacher authentication and a supervised seat.

Check participation and recognition separately

The CCC page allows any full‑time student to participate. Junior suits beginner‑to‑intermediate programmers; Senior suits intermediate‑to‑advanced programmers, regardless of grade.

For official recognition, participants must be born on or after July 1, 2007. Those writing at a school inside Canada must also live in Canada; the listed condition for schools outside Canada, including the U.S., is the birth‑date boundary. Other participants can compete unofficially and earn certificates.

Official status does not guarantee a CCO invitation or a Canadian team place. CCO normally draws top official Senior participants at Canadian schools; CEMC may invite outstanding students, including Canadian citizens or permanent residents studying abroad, at its discretion.

Separate the school order from your account

Your educator orders through the CEMC school portal. A new school account requires a Principal or Head of Math application and may take about three weeks for manual review.

For your student grader account, use the school number supplied by your teacher, who must authenticate you. An existing account may be reusable. Never ask for the confidential school password.

The public login and account pages work, but current 2027 order availability behind the school login has not been verified. This is a preparation guide, not confirmation that your school is accepting entries.

Budget by student and by order

The published price is CAD10 per participant plus CAD5 processing per school order. The CAD5 charge is not per student; ask the teacher how the school order applies to you.

Under the CEMC terms, schools may not charge a contest fee above published CEMC fees, and refunds or cancellations are not offered.

Confirm two dates and the school time

The school ordering deadline is February 11, 2027; an exact cutoff clock and time zone are not stated. Your teacher may need your response earlier. The U.S. and Canada contest date is February 17, 2027, near the beginning of the local school day; confirm the exact start with your school.

There are five problems worth 15 points each: 5 * 15 = 75 points, within three hours. Attempting both levels does not give extra time. Submit your own programs through the grader; see the current language guide for C, C++, Java and Python options.

Prepare a clean coding workspace

The current linked CCC rules allow internet use for editing, compiling, submitting and official language documentation. Other internet use, including chat, web search, code forums and generative AI, is forbidden during the contest.

IDEs are allowed; their AI tools are not. Access to other source or starter code is prohibited, including your own earlier code, in print or electronically.

Adults arrange logistics and supervision; students solve individually. Do not discuss contest problems or solutions online within 48 hours afterward.

HAEA preparation advice: disable AI completion, remove prior code from the workspace and use the practice grader to rehearse access. Read the grader directions, keep practice separate from the live timer, and confirm your teacher's instructions before contest day.
