Please note: This section of the website has not yet been updated with information about ARML 2021. Please check back on March 1. ARML teams currently organizes the teams from Northern California and the San Francisco Bay Area as well as several western states - Arizona, Idaho, Montana, Nebraska, Nevada, New Mexico, North Dakota, South Dakota, and Wyoming - to attend the national American Regions Mathematics League competition each spring. From the links above, you can apply to be on one of this year's ARML teams, or find information specific to your region's team. We encourage applications from any student in our geographical service areas who is currently a senior in high school or younger; there is no lower age limit for participation in ARML, although at our discretion we may require a guardian to accompany extremely young students on the ARML trip. If your region is not one serviced by, feel free to contact us at for help in finding a team near you.

About ARML

The American Regions Mathematics League started in 1976 for the purpose of providing a national (or at that time, regional) competition for the brightest mathematical minds in the nation's high schools. Teams are generally organized on the state level, but some cities (e.g. New York and Chicago) send their own teams. The annual ARML meet is currently held at sites in Pennsylvania, Iowa, Nevada, and Georgia, and students from about half the states and a few foreign countries attend the contest. The awards ceremony is carried on simultaneously at the four sites, and students at the four sites compete against each other for awards. The ARML contest is usually held each year on the Saturday after Memorial Day, and while the contest is intended for high school students, some exceptional junior high students show up each year. Seniors who graduate in the current school year are eligible to compete as well.

The ARML competition is comprised of four tests. First is a 20-minute team test consisting of 10 questions which the entire 15-member team works on together. The team test is worth 5 points per question for a maximum of 50 points. Next comes the Power Question, a one-hour ordeal where the whole team works together to answer a proof-like question consisting of several parts. The Power Question is graded on accuracy, efficiency, and style, and is worth 50 points. Next is the individual round which consists of 10 questions administered in pairs, with 10 minutes allotted to work on each pair of questions. Each correct answer earns the team one point, so maximum is 15 times 10 or 150 points. After the individual round there is a relay round. For the relays each team is divided into 5 teams of 3 students each. The first person works his/her problem and passes it back to the second person, who uses that answer to solve his/her problem. The second person passes the answer to the third person, who uses that answer to get the final answer. There are two relay questions, lasting 6 minutes each. Each 3-member team has an opportunity to turn answers in at 3 minutes and at 6 minutes, and only the answer given by the third person counts. A team receives 5 points if the correct answer is turned in at 3 minutes, and 3 points at 6 minutes, for a total of 50 points possible between the two relay questions.

For more information about ARML, you can visit the official ARML website at Do NOT register for ARML at that site; to participate in ARML you need to sign up through your regional team. See above for the states served by or for the email address to send an inquiry if you attend school outside our jurisdiction.
