Life Master is a chess title awarded by the United States Chess Federation (USCF). To be awarded this title, one must hold a master's rating of over 2200 for at least 300 USCF-rated tournament chess games.
During the 1990s, the USCF also awarded a "Life Master" title on the basis of a different and more complex system that was similar to the FIDE 'norm system' of awarding titles. This method of attaining Life Master became officially recognized by the USCF on January 1, 1996. The "class norm" system was later discontinued, and players who had or were subsequently granted the title on the 300-game basis were renamed "Original Life Masters." In practice, the distinction is rarely made.
As the name of this title implies, this title is held for life, regardless of any subsequent decrease in rating. Thus it is possible to have a player with a USCF rating of 2100 (or below) who is a Life Master. While this is uncommon for 'Original Life Masters' (since such a rating floor can only be dropped by the USCF itself), it is relatively common for Life Masters who earned their title via the now-defunct norm system, since the requirements for that title did NOT require a rating of over 2200. This has led to some holders of the USCF Life Master title having never obtained ratings above 2200.
