A standard of competitive performance that is required in order for a chess player to be awarded one of several titles, such as Grandmaster, International Master, or Woman Grandmaster, etc. The chess organization, such as FIDE, that awards the titles, will establish specifically what a norm is. For example a candidate might achieve a norm if they play in a tournament and face a certain number of grandmasters, and then have a certain number of wins in that tournament against players that are above a certain rating, and so on. If the candidate then collects a certain number of norms, three for example, they will win a grandmaster title. The details that define a norm can be obtained from the chess organization, and the details will change from time to time.
