Southern California ARML
The Southern California ARML Team represents Southern California for the American Regions Mathematics League. We provide coaching, host practices, and organize teams of mathematically gifted youth in order to prepare them for national ARML competition events. More generally, we strive to create a stimulating environment for learning mathematical concepts, and build a community for math students to connect with peers and mentors. Members of our organization are residents of the following Southern California counties: Santa Barbara, Ventura, San Luis Obispo, Los Angeles, Orange, Kern, San Bernardino, and Riverside.

About ARML
American Regions Math League (ARML) is one of the most prestigious math competitions in the United States, with a history spanning over 50 years. Designed as a team-based contest, ARML brings together top middle and high school students from around the globe to compete in a rigorous and collaborative environment. Participants tackle challenging problems through individual rounds, team rounds, and relay-style events. Known for its emphasis on teamwork, speed, and deep problem-solving skills, ARML serves as a premier platform for developing the kind of mathematical thinking that underlies success in advanced STEM fields and the AI era.
