The Chess'n Math Association (or Chess and Math Association) is a non-profit organization dedicated to bringing chess into Canadian schools. Founded in 1985 by Larry Bevand, who still serves as its executive director, it bills itself as "Canada's National Scholastic Chess Organization", although it is not affiliated with the Chess Federation of Canada, Canada's official FIDE-recognized chess organization. Chess'n Math runs hundreds of tournaments for kids K-12 across Canada, including an annual Canadian Chess Challenge. These tournaments are rated according to its own rating system. It also offers chess lessons and camps, produces a magazine Scholar's Mate, and runs the Strategy game stores located in Montreal, Ottawa and Toronto. CMA has sponsored several chess futurity events, to provide international title norm opportunities for promising young Canadian players.
The Chess 'n Math rating system does not differ from that of the FIDE a lot in the way that the formula is derived, but the variables are different. According to their website, [1] the formula is as follows, for one tournament or multi-game event:
As it appears, the number of "expected wins" for one game is equal to the difference in rating divided by 800, plus 0.5. The cutoff value of ±350 makes the limits of these "We" values, 15/16 and 1/16 respectively. A person can also win bonus points equal to:
As of September 1, 2007, a "bonus" of 2 is added to every game won, up to a maximum of 50 games.

A chess title is a title regulated by a chess governing body and bestowed upon players based on their performance and rank. Such titles are usually granted for life. The international chess governing body FIDE grants several titles, the most prestigious of which is Grandmaster; many national chess federations also grant titles such as "National Master". More broadly, the term "master" can refer to any highly skilled chess player.
A chess rating system is a system used in chess to estimate the strength of a player, based on their performance versus other players. They are used by organizations such as FIDE, the US Chess Federation, International Correspondence Chess Federation, and the English Chess Federation. Most of the systems are used to recalculate ratings after a tournament or match but some are used to recalculate ratings after individual games. Popular online chess sites such as chess.com, Lichess, and Internet Chess Club also implement rating systems. In almost all systems a higher number indicates a stronger player. In general, players' ratings go up if they perform better than expected and down if they perform worse than expected. The magnitude of the change depends on the rating of their opponents. The Elo rating system is currently the most widely used.
Performance rating in chess is the level a player performed in a tournament or match based on the number of games played, their total score in those games, and the Elo ratings of their opponents. It is the Elo rating a player would have if their actual score was the expected score they would get against their opponents based on their opponent's individual ratings. Due to the difficulty of computing performance rating in this manner, however, the linear method and FIDE method for calculating performance rating are in much more widespread use. With these simpler methods, only the average rating factors into the calculation instead of the ratings of each individual opponent. Regardless of the method, only the total score is used to determine performance rating instead of individual game results. FIDE performance ratings are also used to determine if a player has achieved a norm for FIDE titles such as Grandmaster (GM).
