What Is the International Math Olympiad?

The International Mathematical Olympiad (IMO) is the world’s premier mathematics competition for high school students, held each year in a different country. First hosted in 1959 in Romania with just seven countries, it has since grown into a global event drawing teams from more than 100 nations across five continents.

In 2026, the 67th IMO will be hosted in Shanghai, China, from July 10 to 20. Teams from over 100 countries are expected to participate, each bringing up to six of their top math students.

While the competition is intense, what makes it truly special is the opportunity for you to meet students from every continent, share ideas, and even form friendships that can last a lifetime.

International Math Olympiad Awards and Prizes

The International Mathematical Olympiad is all about celebrating your problem-solving skills on a global stage. Instead of money, the awards focus on medals that highlight your mathematical ability and hard work. The system is designed to be fair and transparent, ensuring that every participant receives the recognition they deserve.

The scoring process, known as coordination, is a big part of what makes the IMO so respected. Here is how it works:

• First, the leaders and deputy leaders from each country review the solutions submitted by their team members and assign scores based on official criteria.
• Then, coordinators, expert mathematicians assigned to each step of the problem, enter. Their job is to review the solutions, compare reasoning, and ensure fairness. Each coordinator typically handles around 150 papers in just two days, making the process intense yet extremely thorough.
• If there is a disagreement between the coordinators and the country leaders, they meet to work out the correct score. This extra layer of review ensures that every student’s effort is accurately recognized.

Once all the scores are finalized, medals are awarded based on total points. About half of all contestants walk away with a medal, which means you have a real shot at standing on the world stage if you put in the work. The medal distribution follows a clear ratio:

• Gold Medal. Awarded to roughly the top 1/12 of contestants (about 50 students worldwide).
• Silver Medal. Awarded to about twice as many students as the gold.
• Bronze Medal. Awarded to about three times as many students as gold.

Winning a medal at the IMO places you among an elite group of young mathematicians who have shown the ability to solve some of the toughest problems in the world. Earning this achievement carries prestige and respect long after the competition ends.

How to Qualify for the International Math Olympiad

If you dream of representing your country at the International Mathematical Olympiad, the journey starts much closer to home. You must first compete in your country’s national Math Olympiad program. Only the top performers from each nation advance to the IMO, so earning a spot means you are already one of the best young mathematicians in your region.

Each country has its own process for selecting a team. Still, the overall goal remains the same: to identify students with exceptional problem-solving skills in algebra, geometry, combinatorics, and number theory.

Eligibility

To qualify for the IMO, you must:

• Be a high school student who has not yet enrolled full-time in university.
• Be under 20 years old at the time of the competition.
• Qualify through your country’s national math olympiad or selection exams.

Most countries select a six-member team, and your journey typically begins with regional or state-level contests before advancing to the national level. Success at each level is what eventually earns you a chance to compete internationally.

Required documents

Once selected, you do not need to worry about the endless paperwork that is often associated with other academic competitions. The IMO organizers and your national team leaders handle the registration process. 

However, you will need:

• A valid passport for international travel.
• Any consent or permission forms required by your country’s math olympiad organization.
• Basic information like your name, school, and language preference for the exam booklet.

All exam papers and materials are prepared by the IMO system, so once your team submits your details, everything from name tags to translated exam papers is ready for you.

Contest fees

The good news is that contestants are not expected to pay entry fees to the IMO itself. Your country’s Math Olympiad organization fully supports your participation, and the host country provides all the competition materials.

What you may need to think about are:

• Travel and lodging, which are usually covered by sponsors, governments, or math organizations in your country.
• Personal expenses, such as souvenirs or meals outside official activities.

The IMO is designed to enable talented students like you to compete, regardless of your financial background.

Registration deadline

You do not register for the IMO directly. Instead, your national Math Olympiad committee handles everything once you qualify.

What matters for you is staying aware of your own country’s deadlines:

• Local and national contests often take place months before the IMO, usually in late winter or spring.
• Teams are finalized and submitted to the IMO organizers well ahead of the July competition.

As a student, your focus should be on preparing for each round in your country. If you make it to the top six, the registration process is taken care of for you, and you will be officially entered as part of your country’s delegation.

How to Get into the International Math Olympiad

Getting into the International Math Olympiad takes preparation, dedication, and a clear understanding of the selection process in your country. To help you out, here’s the step-by-step journey you’ll need to take if you want to compete on the world stage:

Step 1: Understand how the IMO works.

Timeline: Year-round

The IMO is the most prestigious mathematics competition in the world, and only about 600 students are selected to participate each year. To even have a chance, you’ll need to go through your country’s official selection process. This usually begins with your National Mathematical Olympiad (or another national contest).

Take time to read up on your country’s rules and guidelines. Every country handles things a little differently, but the general path is the same: you start with local contests, move on to the regional or national Olympiad, and from there, the top students are chosen to join the international team.

Step 2: Start with local math competitions.

Timeline: Fall–Winter (the year before the IMO)

Your first step is to join the math contests offered in your school or region. These competitions are often run by your country’s math Olympiad organization. If you want to get ahead, grab past contest papers and start solving them. This practice is one of the best ways to sharpen your problem-solving skills and get familiar with the type of problems you’ll face.

Think of these local contests as your training ground. Performing well here is how you move up to the next level.

Step 3: Compete at the national level.

Timeline: Winter–Spring

If you score well in local rounds, you’ll qualify for your country’s National Mathematical Olympiad. This is where things get serious. The national competition is used to identify the strongest students who might represent the country at the IMO.

At this stage, practice really pays off. Focus on improving speed, accuracy, and developing creative approaches to problem-solving. Many countries also host training camps for top performers, so making it this far often means you’ll get extra coaching and exposure to advanced problem sets.

Step 4: Train with your country’s team program.

Timeline: Spring–Early Summer

Students who excel at the national level are typically invited to a training program or camp. This is a huge milestone because it means you’re being considered for the national team.

During training, you’ll tackle high-level problems that are similar to actual IMO questions. The focus is on problem-solving techniques across algebra, number theory, combinatorics, and geometry. You’ll also be mentored by mathematicians, past Olympiad participants, or professors who help you refine your skills.

Step 5: Make the final team selection.

Timeline: Early Summer

After training, your country will select its final IMO team. Most countries send six students to represent them at the competition. The selection is usually based on your performance during training camps and national exams.

This step is competitive, but remember: even if you don’t make the final six, reaching this stage already means you’re among the top young mathematicians in your country.

Step 6: Represent your country at the IMO.

Timeline: July (summer of the competition year)

If you make the cut, congratulations! You’ll officially represent your country at the International Math Olympiad. The event typically lasts around 10 days and changes locations each year. For example, the 67th IMO will take place in Shanghai, China, from July 10 to 20, 2026.

During the Olympiad, you’ll face two intense exam days where you’ll solve six of the most challenging math problems you’ve ever seen. Between those exams and the grading process, you’ll get the chance to join cultural activities, meet students from over 100 different countries, and experience what it’s like to be part of a global community of math enthusiasts.

Winning a medal is an incredible achievement, but just being there is already a huge honor. Many universities and scholarship programs actively seek out IMO participants because they’re recognized as some of the brightest problem solvers in the world.

How to Win the International Math Olympiad

Winning at the IMO takes more than just raw math skills. You need to understand how the competition works, prepare for the unique challenges, and know how medals are actually awarded. Here are some practical tips to help you aim for the podium:

1. Know how the competition runs.

The IMO lasts about ten days, and everything is tightly scheduled. First, the International Jury (a group of expert mathematicians) meets to select the six official problems. Then you’ll have the two exam days, where you’ll face three problems each day. You get four and a half hours per exam, which means every minute counts. After that comes grading, coordination, and finally the medal ceremony.

When you understand this structure, you can plan your preparation and test strategy better. For example, you should practice solving three problems in 4.5 hours to mimic the real thing.

2. Train for original, tough problems.

Every problem at the IMO is designed to be challenging, creative, and solvable using only “elementary” math tools. However, don’t let the word “elementary” fool you; the level is extremely high. Problems are carefully chosen to be original and not something you’ve seen before in your national Olympiads.

This means you should go beyond just drilling past papers. Work on developing your problem-solving creativity. Ask yourself: what’s a clever trick or new way to look at this problem? That mindset is what separates medalists from the rest.

3. Practice under strict exam conditions.

During the contest, you’ll be carefully monitored. You can’t bring anything other than approved tools, and you’ll be seated in fixed spots since exams are distributed in different languages. For the first 30 minutes, you’re allowed to ask for clarifications, but after that, you’re on your own.

The best way to get ready is to simulate this pressure. Sit down with three problems, give yourself exactly 4.5 hours, and follow the rules. No phones, no extra notes. This builds the focus and stamina you’ll need to stay sharp for two long exam days.

4. Understand how scoring works.

Each problem is worth up to 7 points, and your leaders first grade your solutions before negotiating with international coordinators. These coordinators are mathematicians who specialize in grading one of the six problems and will compare your solutions with the scoring criteria. This process is designed to be completely fair and transparent.

To maximize your score, show every step of your reasoning. Even partial solutions can earn points if they demonstrate a solid idea. Don’t skip writing down your approach just because you couldn’t finish; sometimes those steps make the difference between 0 and 3 points.

5. Aim for consistency across problems.

About half of all contestants win a medal, but the medal distribution follows a clear ratio: gold goes to roughly 1 in 12 students (about 50 worldwide), silver goes to about twice as many, and bronze goes to about three times as many. That means you don’t necessarily need a perfect score to medal. You just need a strong, consistent performance across problems.

Rather than obsessing over solving every question, focus on securing solid points on as many problems as possible. For example, two complete solutions and strong partial credit on another problem could put you in medal range.

6. Value the experience as much as the result.

While medals are prestigious, one of the biggest wins is meeting students from around the world who love math as much as you do. When you go in with the mindset of learning, connecting, and challenging yourself, you’ll find that the whole experience fuels your growth as a mathematician, which often leads to better performance in the long run.
