USAMO Eligibility Criteria
Eligibility for the USAMO is determined by performance on preceding exams in the AMC series. The criteria ensure that participants have demonstrated a high level of mathematical aptitude.

Selection Process Details
The Mathematical Association of America (MAA) invites a set number of students each year based on a selection index. This index is a weighted combination of a student's AMC 10/12 score and AIME score. The specific formula and the minimum qualifying index are determined by the MAA after the AIME is graded. Separate, though similar, criteria exist for the USA Junior Mathematical Olympiad (USAJMO) for students in grade 10 and below.
