Dedicated to making mathematics enjoyable and strengthening the mathematical skills of our nation's students, the American Math Competitions (AMC) program encourages interest in mathematics through a series of national contests, the Mathematical Olympiad Summer Program (MOSP), and US participation in the International Mathematical Olympiad. More than 400,000 students participate in the competitions each year, which consist of a series of increasingly challenging tests culminating in the United States Mathematical Olympiad (USAMO). The top 60 performers are invited to attend the MOSP. The top six students represent the USA in the International Mathematical Olympiad (IMO) and two girls teams compete in the China Girls Mathematical Olympiad. The three week summer "camp" is designed to stimulate continuing interest in mathematics and help prepare for future study in the discipline. Furthermore, the contests identify exceptional talent early-USAMO and IMO winners from past years have become top mathematicians, scientists, and business leaders.
