The Euclid Mathematics Contest is one of the most prestigious and widely recognized high school mathematics competitions in North America. Every April, tens of thousands of students from Canada and around the world participate in this challenging contest, organized by the Centre for Education in Mathematics and Computing at the University of Waterloo. But the Euclid, as we know it today, is the product of decades of evolution, shaped by changes in mathematics education, technological advances, and the growing importance of STEM fields in the global economy.

In this article, we explore the rich history and evolution of the Euclid Mathematics Contest, from its origins in the early 1980s to its current status as a cornerstone of Canadian mathematics education and a gateway to university admissions and scholarships. Understanding this history provides valuable context for students, parents, and educators, and sheds light on why the Euclid has endured and thrived for over four decades.
The Ancient Namesake: Euclid of Alexandria
The contest takes its name from Euclid of Alexandria, a Greek mathematician who lived around 300 BCE and is often referred to as the Father of Geometry. Euclid is best known for his work Elements, a thirteen-volume treatise that systematized the mathematical knowledge of his time and established the foundations of geometry as we know it. The Elements was one of the most influential works in the history of mathematics, serving as the primary textbook for teaching geometry for over two thousand years.
Euclid is also remembered for his rigorous approach to mathematical proof. He began with a small set of axioms and postulates, and from these, he derived hundreds of theorems through logical deduction. This emphasis on logical reasoning and clear proof is precisely what the modern Euclid Contest seeks to test. Just as the ancient Euclid valued precision and rigor in mathematics, the modern contest rewards students who can construct clear, logical, and well-presented solutions to challenging problems.
The Founding of CEMC and the Early Years

The story of the Euclid Contest begins with the founding of the Centre for Education in Mathematics and Computing at the University of Waterloo in 1980. The University of Waterloo itself was established in 1957 as Waterloo College Associate Faculty, and it quickly became known for its strength in mathematics, computer science, and engineering. By the late 1970s, the university recognized the need for an organization dedicated to promoting mathematics and computer science education at the secondary school level.
CEMC was founded with a mission to strengthen mathematics and computer science education across Canada. One of its earliest and most ambitious projects was the creation of a national mathematics contest for high school students. The goal was to identify and encourage mathematically talented students, to provide a challenge beyond the standard curriculum, and to establish a standardized measure of mathematical ability that universities could use in their admissions processes.
The first Euclid Contest was held in April 1980, with a modest number of participants from schools across Ontario. The contest was designed to be accessible to any Grade 12 student with a strong background in mathematics, while still providing a challenge for the most talented students. The format was similar to what it is today: a two-and-a-half-hour exam consisting of ten questions requiring full written solutions.
Growth and Expansion in the 1980s and 1990s

Throughout the 1980s and 1990s, the Euclid Contest experienced steady growth in both participation and prestige. As the University of Waterloo established itself as a leading institution for mathematics and computer science, the Euclid became increasingly recognized as a valuable tool for identifying talented students. The contest also benefited from the growing emphasis on STEM education in Canada and North America more broadly.
During this period, CEMC expanded its offerings beyond the Euclid. The organization introduced a suite of contests for younger students, including the Gauss Contest for Grades 7 and 8, the Pascal Contest for Grade 9, the Cayley Contest for Grade 10, and the Fermat Contest for Grade 11. These contests created a pipeline of mathematical talent, encouraging students to develop their skills from an early age and preparing them for the challenges of the Euclid in their final years of high school.
The 1990s also saw the Euclid become more closely integrated with university admissions, particularly at the University of Waterloo. The Faculty of Mathematics began to use Euclid scores as a formal component of its admissions process, recognizing that the contest provided a more objective and standardized measure of mathematical ability than high school grades alone, which could vary significantly across schools and provinces.
The Digital Age and Global Expansion

The turn of the millennium brought significant changes to the Euclid Contest, driven by the rise of the internet and the growing globalization of education. CEMC began publishing past contests and official solutions on its website, making these valuable resources freely available to students around the world. This was a transformative development, as it allowed students who did not have access to specialized coaching or expensive preparation materials to prepare effectively for the contest.
During this period, the Euclid also began to attract international participants in increasing numbers. Schools outside Canada, particularly in the United States, Asia, and Europe, began to register their students for the contest, recognizing its value as a measure of mathematical ability and as a credential for university applications. Today, the Euclid is written by students in dozens of countries, making it one of the most internationally recognized high school mathematics competitions.
The digital age also transformed how students prepare for the contest. Online forums, such as the Art of Problem Solving community, became popular platforms for students to discuss problems, share strategies, and learn from one another. YouTube channels, educational websites, and mobile apps provided additional resources for practice and learning. The Euclid, once a contest that could only be accessed through schools, became part of a global ecosystem of mathematics education.
The Euclid and University Admissions: A Deepening Relationship
As the Euclid grew in prestige, its role in university admissions became increasingly important. The University of Waterloo, in particular, deepened its reliance on Euclid scores as a key component of its admissions process for the Faculty of Mathematics and the Faculty of Engineering. The university developed a sophisticated system for combining Euclid scores with high school averages to calculate an Admission Average, which is used to rank applicants for competitive programs such as Computer Science and Software Engineering.

This relationship between the Euclid and university admissions has had several important consequences. First, it has made the contest more competitive, as students recognize that a strong Euclid score can significantly improve their chances of admission to top programs. Second, it has led to the development of a robust scholarship ecosystem, with millions of dollars in merit-based scholarships tied to Euclid performance. Third, it has elevated the status of the Euclid among students, parents, and educators, who now view it not just as an academic challenge but as a critical stepping stone to university success.
Other Canadian universities have followed Waterloo lead, with institutions such as the University of Toronto, the University of British Columbia, McGill University, and Western University also considering Euclid scores in their admissions and scholarship decisions. The Euclid has thus become a nationally recognized standard for mathematical ability, valued across the Canadian higher education system.
Modern Challenges and Adaptations
In recent years, the Euclid Contest has faced new challenges that have required adaptation and innovation. The rise of artificial intelligence and large language models, for example, has raised questions about academic integrity and the potential for students to use AI tools in their preparation. CEMC has responded by emphasizing the importance of original work and clear mathematical communication, which are difficult to replicate with AI assistance.
The COVID-19 pandemic also presented significant challenges. In 2020 and 2021, many schools were closed or operating remotely, making it difficult to administer the contest in its traditional format. CEMC responded by offering flexible testing arrangements and providing additional online resources to support students preparing for the contest under difficult circumstances. The pandemic also accelerated the adoption of digital tools in mathematics education, with more students than ever using online platforms for practice and learning.

Another modern challenge is the growing diversity of the student population. As the Euclid attracts participants from an increasingly wide range of backgrounds, including students for whom English is not a first language and students from educational systems with different curricula, CEMC has worked to ensure that the contest is accessible and fair to all. This includes careful attention to the language used in contest problems, as well as efforts to promote the contest in underrepresented communities.
The Enduring Value of the Euclid
Despite these challenges, the Euclid Mathematics Contest has endured and thrived for over four decades. Its continued success can be attributed to several factors. First, the contest is rigorous and well-designed, with problems that are challenging but accessible to any student with a strong mathematical background. Second, the contest is fair and objective, providing a standardized measure of ability that is not subject to the biases and inconsistencies of other admissions criteria. Third, the contest is freely available to all students, with past exams and solutions published online at no cost.
The Euclid also benefits from the strong reputation of the University of Waterloo and CEMC. The university is widely regarded as a leader in mathematics and computer science education, and its endorsement of the contest lends it credibility and prestige. The long history of the contest, stretching back to 1980, has also contributed to its reputation as a time-honored tradition in Canadian mathematics education.
Looking to the Future
As the Euclid enters its fifth decade, it faces both opportunities and challenges. The growing importance of STEM fields in the global economy is likely to increase the demand for contests like the Euclid, as students seek ways to demonstrate their mathematical abilities and as universities look for reliable ways to identify talented candidates. At the same time, the contest will need to continue adapting to changes in technology, education, and society to remain relevant and effective.
One potential area of growth is the expansion of the Euclid to new audiences. As more schools around the world adopt the contest, CEMC may need to develop new resources and support systems to serve this growing international community. There may also be opportunities to use technology to enhance the contest experience, such as offering practice exams with instant feedback or providing personalized learning recommendations based on student performance.
Another important consideration is the role of the Euclid in promoting equity and inclusion in mathematics education. As the contest becomes more competitive, it is important to ensure that all students, regardless of their background, have access to the resources and support they need to succeed. CEMC has made efforts in this direction, but there is always more work to be done to ensure that the Euclid is accessible and welcoming to students from all walks of life.
The Legacy of the Euclid
The Euclid Mathematics Contest is more than just a test. It is a tradition that has shaped the lives of hundreds of thousands of students over the past four decades. For many, the Euclid was their first encounter with the beauty and challenge of advanced mathematics. For others, it was a gateway to university admissions, scholarships, and careers in STEM fields. And for all who participate, it is an opportunity to test their abilities, to challenge themselves, and to join a community of students who share a passion for mathematics.
As we look back on the history of the Euclid, we can see how it has evolved and adapted to meet the needs of each generation of students. From its humble beginnings in 1980 to its current status as a globally recognized contest, the Euclid has remained true to its core mission: to challenge, inspire, and recognize mathematical talent.
