What Is the High School Mathematical Contest in Modeling (HiMCM)?

The High School Mathematical Contest in Modeling (HiMCM), organized by the Consortium for Mathematics and Its Applications (COMAP), is an international team-based mathematics competition that challenges high school students to solve real-world problems using mathematical modeling.

The contest requires a strong foundation in high school-level math, and not calculus or college-level coursework. It aims to evaluate how effectively students apply familiar concepts to unfamiliar, interdisciplinary situations and justify any assumptions clearly. Past problems have involved logistics optimization, systems modeling, and data-driven design challenges.

Each year—typically in November—COMAP releases two open-ended problem scenarios. As of now, official details for the 2026 HiMCM contest cycle have not yet been released.

Teams of up to four students select one problem and have 14 days to develop a mathematical model and submit a formal solution paper. Each team works under the supervision of an adult advisor who handles registration and compliance, but all modeling and writing must be done independently by students.

First held in the late 1990s, HiMCM has grown into a globally recognized competition. By 2025, it marked its 28th annual cycle, with hundreds of teams participating worldwide. HiMCM serves as the high school counterpart to COMAP’s undergraduate Mathematical Contest in Modeling, placing students within a well-established tradition of applied math.

High School Mathematical Contest in Modeling (HiMCM) Awards and Prizes

Rather than numerical rankings, COMAP assigns designation levels reflecting overall quality. From lowest to highest, these are: Unsuccessful, Successful Participant, Honorable Mention, Meritorious, Finalist, and Outstanding Winner. Only a very small fraction of teams earn the top distinction. For example, in 2023, just 9 out of 967 teams received Outstanding Winner status.

All submitting teams receive a digital certificate of participation. Teams earning higher distinctions gain broader visibility: COMAP publicly posts results, issues official announcements, and frequently sees Outstanding teams recognized by schools, districts, and media outlets. High-performing papers may also be highlighted as exemplary student work.

Since 2024, COMAP, together with the National Council of Teachers of Mathematics (NCTM), has also awarded the NCTM Award to select top teams (two HiMCM Outstanding teams and one MidMCM team annually).

A major opportunity tied to strong performance is advancement to the International Mathematical Modeling Challenge (IM²C). U.S.-based teams earning Meritorious, Finalist, or Outstanding designations are invited to compete internationally in the spring. Only a small number of teams per country receive this invitation; for instance, the top two U.S. teams from HiMCM 2024 represented the United States at IM²C 2025. Other MidMCM Finalist and Outstanding teams may also qualify for a junior IM²C division.

How to Qualify for the High School Mathematical Contest in Modeling (HiMCM)

Qualifying for the HiMCM is really just meeting the eligibility criteria and completing the registration steps.

Here’s what you need to know to ensure you and your team qualify:

Eligibility

HiMCM is open to students enrolled in high school, including those from public, private, international, online, and homeschool settings. Each student may participate on only one team per contest.

Each team must consist of 2–4 students. All team members must be affiliated with the same school or educational program at the time of the contest. However, beginning in 2025, teams may also be formed through legitimate educational programs such as math circles, enrichment programs, magnet programs, homeschool cooperatives, or accredited online schools. There is no limit to the number of teams a school or educational program may enter.

Teams may not be formed through private tutoring or coaching services created solely for contest participation.

Required documents

Each team must have a designated adult advisor affiliated with the same school or educational program. The advisor is typically a teacher, administrator, coach, or program leader.

During registration, advisors must submit:

• Team information
• Institutional affiliation
• Advisor details

All students—and their parents or guardians—must agree to contest rules and consent forms as part of the online registration process. Once registration is complete, teams receive a control number that replaces their names on the solution paper to ensure blind judging.

Contest fees

The HiMCM registration fee is $100 per team. This nonrefundable fee covers contest administration and judging. Payment is submitted during online registration.

Registration deadline

Registration typically remains open until shortly before the contest begins in early November. For example, in 2025, registration closed at 2:00 PM Eastern Time on November 5, immediately before the contest window opened.

Teams must complete registration, submit payment, and receive a control number before the deadline in order to compete.

How to Get into the High School Mathematical Contest in Modeling (HiMCM)

If you’re aiming to participate in the next HiMCM, here’s a step-by-step guide:

1. Form your team.

HiMCM teams consist of 2–4 students from the same high school or approved educational program. Choose teammates who work well together and bring complementary strengths (such as modeling, computation, or writing).

If your school cannot field a team, you may form one through an approved program like a math circle, enrichment program, or homeschool cooperative, provided it meets COMAP eligibility rules.

2. Find an advisor.

Each team must have an adult advisor affiliated with the same school or program. This is usually a math or science teacher, but may also be another faculty member, administrator, coach, or program leader.

The advisor’s role is only administrative and may not assist with problem solving or writing. One advisor may oversee multiple teams.

3. Register your team.

When registration opens (typically September–October), your advisor registers the team through the official HiMCM portal run by COMAP. Registration requires team member details, school or program affiliation, advisor information, and payment of the $100 per-team fee.

Registration closes shortly before the contest begins in early November, and late entries are not accepted. Once registered, COMAP assigns a team control number.

4. Prepare and practice.

Review past HiMCM problems and sample solutions to understand expectations. Use COMAP’s free resources to review modeling strategies and common pitfalls. Teams should also ensure familiarity with basic statistics, equation building, data analysis, and simple programming or spreadsheet tools.

Plan logistics in advance: decide how and when your team will meet during the 14-day contest period, and assign roles for research, modeling, computation, and writing. COMAP estimates that around 36 hours of focused work is sufficient if time is managed well.

5. Confirm contest dates and rules.

HiMCM typically runs in early November (for example, November 5–18 in 2025). Confirm official dates once announced and block out key work periods, especially the opening days and final submission window. Review contest rules carefully before the start. Teams may not discuss problems with anyone outside the team once the contest begins.

External resources (books, websites, datasets, software) are allowed but must be cited. Solution papers must follow formatting limits specified in the instructions. Rule violations can result in disqualification, so clarity on requirements is essential before the contest starts.

How to Win in the High School Mathematical Contest in Modeling (HiMCM)

Winning HiMCM—achieving that Outstanding or Finalist designation—is no easy feat, but with smart strategies and hard work, it’s attainable. Here are some tips and best practices to help your team perform well in the contest:

1. Choose the right problem.

At the contest start, teams receive two problem options (A and B). Read both carefully before deciding. Choose the problem your team understands better and can engage with more deeply.

Consider alignment with your strengths (e.g., geometry, optimization, simulation, statistics) and whether you can quickly outline a viable approach. A strong initial problem choice sets the direction for the entire submission.

2. Create and follow a game plan.

Before doing detailed math, outline your approach. Identify key questions, relevant mathematical tools, required data, and assumptions. Build a clear timeline for the 14-day window: early days for problem analysis and research, middle days for modeling and testing, and final days for writing and revision.

Assign roles based on strengths, but plan checkpoints to integrate work and cross-check each other’s math and writing. Virtual collaboration is allowed and effective if managed carefully.

3. Emphasize clarity and communication.

Judging is based entirely on the written report, so clarity matters as much as correctness. A strong paper typically includes:

• Introduction (problem restatement and approach)
• Assumptions (with justification)
• Model development
• Analysis and results
• Limitations or error analysis
• Conclusion

Define variables, label figures, and explain reasoning clearly. Avoid unnecessary jargon. Proofread carefully and ensure all parts of the prompt are addressed.

4. Demonstrate mathematical insight.

Top papers go beyond a basic solution. Strong teams analyze sensitivity, justify assumptions, discuss limitations, and consider alternatives. Aim for models that are as simple as possible while still being effective, and explain every major decision.
