Explanations of Awards

• Average score: Average score of all participants, regardless of age, grade level, gender, and region.
• AIME floor: Before 2020, approximately the top 2.5% of scores on the AMC 10 and the top 5% of scores on the AMC 12 were invited to participate in AIME. Since 2020, the AIME floor has been set to a higher percentage of scores, possibly to allow a consistent number of AIME qualifiers, rather than a fixed percentage.
• Distinction: First awarded in 2020. Top 5% of scores on the AMC 10/12.
• Distinguished Honor Roll: Top 1% of scores on the AMC 10/12
