United States of America Mathematical Talent Search
History of contest
Professor George Berzsenyi initiated the contest in 1989 under the KöMaL model and under joint sponsorship of the Rose-Hulman Institute of Technology and the Consortium for Mathematics and its Applications.
As of 2004, the USAMTS is sponsored by the National Security Agency and administered by the Art of Problem Solving foundation. There were 718 participants in the 2004-2005 school year, with an average score of 49.25 out of 100.
The competition is proof and research based, Students submit proofs within the round's timeframe (usually a month), and return solutions by mail or upload their solutions in a PDF file through the USAMTS website. During this time, students are free to use any mathematical resources that are available, so long as it is not the help of another person. Carefully written justifications are required for each problem.
Prior to academic year 2010–2011 the competition consisted of four rounds of five problems each, covering all non-calculus topics. Students were given approximately one month to solve the questions. Each question is scored out of five points; thus, a perfect score is .
In the academic year 2010-2011, the USAMTS changed their format to two rounds of six problems each, and approximately six weeks are allotted for each round.
The format is now three problem set, each 5 problems and lasting about a month each. Every question is still worth 5 points making a perfect score .
The graders also submit suggestions on possible improvements to the students' solutions with the scores.
Prizes are given to all contestants who place within a certain range. These prizes include a shirt from AoPS, software, and one or two mathematical books of varying difficulty. Prizes are also awarded to students with outstanding solutions in individual rounds. Further, after the third round, given a high enough score, a student may qualify to take the AIME exam instead of qualifying through the AMC 10 or 12 competitions.
