National
Computing Challenge

NCC Overview

By offering one unified challenge, the NCC provides a constructive way for students across grades 5 - 12 to engage with the same set of computational problems while gaining valuable insight into their own reasoning strengths. This consistent structure ensures that all participants are evaluated through shared core concepts, while achievement is measured relative to grade category so that performance remains fair, meaningful, and developmentally appropriate.

The later questions integrate higher-order reasoning tasks—such as abstraction, algorithmic planning, and data-logic applications—that naturally align with learning outcomes found in Grades 9–12 computer-science and mathematics curricula.

For students in Grades 9–12, the contest adds an extra layer of challenge by testing reasoning efficiency: in cases where perfect scores occur, completion time serves as a ranking factor for distinction. This rewards both accuracy and agility in computational thinking—key attributes for advanced analytical work and real-world problem solving.

Distinction scores are determined within each grade category, maintaining fairness while promoting high standards. By preparing for and participating in this challenge, students deepen their understanding of core computational principles and strengthen the logical-reasoning skills that are increasingly vital in today’s technology-driven world.

What Sets This Challenge Apart: The National Computing Challenge stands out as one of the best benchmarks for assessing computer science-related skills. It serves as a true bar for evaluating student potential in computational logic, problem-solving, and related fields without requiring prior programming knowledge. Developed by individuals with backgrounds rooted in computer science from the University of Toronto and guided by experienced educators, as well as Mensa leadership, this challenge incorporates cutting-edge, real-world insights and presents a meaningful challenge that pushes students to work to their fullest potential. By preparing for and participating in this challenge, students enhance their understanding of core computer science principles and build confidence in their logical reasoning skills.

Overview: Participants will engage in a 50-minute, online, proctored test with software designed to prevent cheating and ensure fair play. The challenge includes questions that cover various aspects of computer science logic and math, making it suitable for elementary and middle-grade students. The scoring system awards one point for any unanswered question to prevent guessing and encourage honest assessment.

Test Structure:

• Easy: 6 questions, 24 points total (recommended time: 12 min)

• Medium: 4 questions, 24 points total (recommended time:16 min)

• Challenging: 3 questions, 24 points total (recommended time: 22 min)

Registration Details: Member schools and organizations will send the registration form to eligible families.  Please email your school or organization administrator to request the sign up form.

This year's registration deadline is November 16.  The contest may be written from a computer at any time from November 18 - 23. 

Recognition: Every participant will receive a certificate of participation, while students who perform with distinction will receive distinction certificates. Certificates will be issued on November 25.
