Mathematical Olympiad Program

American intensive math course The Mathematical Olympiad Program (MOP), formerly called the Mathematical Olympiad Summer Program (MOSP), is an intensive summer program sponsored by the Mathematical Association of America. The main purpose of MOP, held since 1974, is to select and train the six members of the U.S. team for the International Mathematical Olympiad (IMO). Selection Process Students qualify for the program by scoring highly on the United States of America Mathematical Olympiad (USAMO) or United States of America Junior Mathematical Olympiad (USAJMO). Before 2012, the top twelve American scorers from all grades formed the "black" group. The approximately eighteen next highest American scorers among students from 11th grade and below form the "blue" group. In 2004, the program was expanded to include approximately thirty of the highest-scoring American freshmen and sophomores each year, the "red" group; this was later split into two, forming the "green" group, which consists of approximately fifteen of the highest-scoring freshmen and sophomores who have qualified through the USAMO, and the "red" group, which consists of those who have qualified through the USAJMO.
