A Grandmaster (GM) is a title awarded to chess players by the world chess organization FIDE, and it is the highest title a chess player can attain, apart from World Champion). Once achieved, the title is held for life, though exceptionally the title can be revoked for cheating). The title of Grandmaster, along with the lesser FIDE titles of International Master (IM), FIDE Master (FM), and Candidate Master (CM), is open to all players regardless of gender). To become a Grandmaster, a player must achieve a 2500 FIDE classical rating and three GM norms. Each GM norm is extremely difficult to attain, and there are many rules for what constitutes a norm. In essence, a player needs a 2600+ performance rating in a nine-round FIDE tournament, and several of their opponents must be from federations/countries other than their own and also be titled. The minimum rating for the IM title is 2400, and to qualify for an FM title, a player must achieve a FIDE Rating of 2300 or more. The Candidate Master (CM) title is similar to FM, but with a FIDE Rating of at least 2200.
