The Mathematical Association of America (MAA) is a professional society that promotes the understanding and appreciation of mathematics. It sponsors the USAMO and other mathematics competitions.

The USAMO is open to high school students who are citizens or permanent residents of the United States.

Approximately 300 students are invited to participate in the USAMO each year.

The USAMO consists of two 3-hour exams, each with six problems.

The USAMO is a very difficult competition. The problems are designed to challenge the most talented high school mathematicians in the United States.

The top three finishers in the USAMO receive gold medals, the next six finishers receive silver medals, and the next twelve finishers receive bronze medals.

Winning the USAMO is a prestigious honor that can increase your chances of being admitted to a top university and lead to a career in mathematics.
