The International Mathematical Modeling Challenge (IM²C)
The International Mathematical Modeling Challenge (IM²C) invites secondary school students from around the world to apply mathematics to authentic real-world problems. Working in teams, students analyze complex situations, develop mathematical models, and communicate their findings through professional-quality reports.
Unlike traditional mathematics competitions that focus on solving well-defined problems, IM²C challenges students to investigate open-ended questions where there may be multiple valid approaches and no single correct answer.
Competition Overview
IM²C is an international mathematical modeling competition for secondary school students. Teams of up to four students work collaboratively to solve a real-world problem over a consecutive five-day period.
Participants draw upon mathematics, data analysis, research, critical thinking, and communication skills to develop and defend their solutions. The competition emphasizes creativity, teamwork, and the ability to apply mathematics in meaningful contexts.
At the conclusion of the competition, submissions are evaluated by an international panel of judges. Top-performing teams receive international recognition, and selected teams may be invited to participate in the IM²C International Summit and Awards Ceremony.
How IM²C Works
IM²C is conducted through participating countries and regions around the world, each of which may select up to two teams to represent them in the international competition.
Once the competition period begins, teams choose a consecutive five-day window during which they work together to analyze the challenge problem and prepare their submission.
Throughout the process, students are expected to:
Teams may use any inanimate resources, including books, websites, software, and data sources. However, all analysis and problem-solving must be completed by the student team members themselves.
Judging & Awards
Submissions are evaluated by an international panel of judges with expertise in mathematical modeling and related disciplines.
Judges evaluate submissions based on the quality of the modeling process, the effectiveness of the analysis, the reasonableness of assumptions, and the clarity of communication.
Teams may receive one of four levels of recognition:
Outstanding teams may have their solution papers or abstracts published and are recognized during the IM²C International Summit and Awards Ceremony.
International Summit
IM²C culminates in an International Summit and Awards Ceremony that brings together students, educators, organizers, and guests from around the world.
The event celebrates outstanding achievement in mathematical modeling while providing opportunities for participants to connect with peers, share ideas, and engage with the broader international modeling community.
Hosted in conjunction with the awards ceremony, the Summit highlights the global impact of mathematical modeling education and provides a forum for collaboration, learning, and recognition.
