American Regions Mathematics League (ARML)
ARML Local Date: Apr. 25, 2026 (Sat.) 14:00-16:50
ARML Power Round I Date: Oct. 25, 2025 (Sat.) 14:00-14:45
ARML Power Round II Date: Feb. 21, 2026 (Sat.) 10:00-10:45
Introduction
ARML runs four contests during the year: the ARML Local contest, ARML Power Round I, ARML Power Round II, and International Competition. Both the ARML Local and Power (I&II) contests are organized by schools and students can sit for the exams within the school, which allow a wider range of students who are interested in mathematics to compete. ARML and IRML are co-hosted by Pennsylvania State University, the University of Georgia, Iowa State University and the University of Nevada Las Vegas. The ARML Local competition consists of multiple rounds, including a team round, an individual round, a tiebreaker round and a relay round. The ARML Power (I&II) Contest is proof based, mirroring the power round in the main ARML competition and testing students' mathematical skills as well as their ability to clearly explain their proofs and reasoning. Students who score well in the ARML Local competition in China will be invited to attend the ARML Power Contest.

Official ARML Local China Invitation Letter
Hello!
On behalf of the executive board of the American Regions Mathematics League, I would like to invite mathematics teachers and coaches in China to organize teams for the ARML Local China, coordinated by ASEEDER. The primary ARML brings together the top mathematics students from around the country and is held in late May or early June every year, and this year we had over 150 teams of 15 students competing at four sites around the United States. In 2008, we decided to introduce ARML Local that could be completed at schools and encouraged teams to invite other local schools to compete, essentially creating ARML Local contest sites around the country. We now wish to extend that invitation to schools throughout China to compete in ARML Local.
The contest format for ARML Local is similar to our main contest, mixing both team and individual elements. Teams consist of six students, and a school may field as many teams as they like. There is a 15 question Team Round that is worked together by each team for 45 minutes, followed by five pairs of Individual Round questions, with 10 Minutes per pair.
The final round is the Relay Round, where teams break up into groups of two, three, and six, and the answer to the first person’s question is needed to solve the second person's question, and so on. We will generate results for ARML Local, ARML Local China, and an aggregated results list so that teams can see how they stack up against teams from their own country and from around the world.
We welcome your participation in ARML Local China and thank ASEEDER for coordinating the contest.
Sincerely,
Paul Dreyer, Ph.D.
President, American Regions Mathematics League
The diffenence between ARML and AMC
ARML | AMC10/12 | |
---|---|---|
Format | 6 people in a team. Rounds: individual round, team round, relay round and tie breaker. | Individual |
Contest Problems | Simple answer and proof-based problems | Multiple choices |
Difficulty | Difficult | Easier |
Duration | 160 minutes | 75 minutes |
Outcomes | Improve teamwork, problem solving skills, inspire students to enjoy and further explore math. | Showcase individual competence through solving challenging problems. |
Competition Date | Held globally on the same day. | Schools decide competition date within a fixed period. |
Target | Regional competition, difficult and challenging for students, American schools select top students from AMC to attend ARML. | Held in schools as the first round of selection for the US Math Olympiad. |
Coach and Participants
I have been participating in ARML for 8 years: 3 years as a student and 5 years as a coach. I recommend students to participate in ARML, as they can improve key skills such as teamwork and problem solving, which are very important for their future life and career. I'm excited to know that ARML Local is being introduced into China, because it gives Chinese students who love math the opportunity to easily participate in the American top math challlenge from their own cities.

ARML has taught and given me a lot, and I am lucky to have grown up in the San Francisco Bay Area, which is the best performing area in the ARML math competitions. Our ARML team often meets and practices at weekends, and I have made lots of friends with the same interests during these practices. Whilst studying at MIT University, I will apply to be an ARML coach in the area, and I hope to share my experiences and knowledge with others.

Coach for ARML, participated in ARML for 3 years
I represented the New York City Team in ARML for 3 years. I loved it when I first participated in this challenge. Different from other challenges, ARML requires team cooperation, and all the rounds are very exciting. In my eyes, ARML attracts people who love math, so I have made friends with the top people in math, who have become my lifelong friends.

Language Chinese and English
Date: Apr. 25, 2026 (Sat.) 14:00-16:50 (170 mins)
Location: Onsite/Online
Competitors:A team of 6 high school students


Format and rules:
- Team round consists of 15 simple answer problems with 4 points for each correct answer and a maximum score of 60 points.
- Individual round consists of 5 rounds; each round begins with 2 simple answer problems lasting 10 minutes. At the end of the round, questions for the next round will be handed out. For each correct answer, 1 point will be awarded. The maximum score available is 60 points within one team.
- Tiebreaker round (10 minutes tiebreaker containing only 1 problem; The tiebreaker round is only for the individual rankings and has no effect on team round results.)
- Relay round
a. 3 rounds. The first player passes his / her answers to the second player, and the second player needs to solve problems based on the answers from the first player. This player then passes the answers to the next player.
b. In Round 1, all correct answers are worth 2 points at 3 minutes and 1 point at 6 minutes. In Round 2, all correct answers are worth 4 points at 4 minutes and 2 points at 8 minutes. In Round 3, the correct answer is worth 6 points at 5 minutes and 3 points at 10 minutes. If an incorrect answer is submitted to the proctor after a correct one, no points are awarded to that squad. Up to 20 points are possible in this round.
