Correspondence Chess Master

Correspondence Chess Master, abbreviated CCM, is an international player title awarded by the International Correspondence Chess Federation, or ICCF. It certifies results within the correspondence system, where games are played remotely under long time controls and separate regulations.

In ICCF's title list, CCM stands above Correspondence Chess Expert and below Correspondence Chess International Master. The title does not expire once it has been confirmed and registered.

Main qualification requirements

• The normal route is to achieve two or more CCM results in qualifying international title tournaments.
• Those results must cover at least 24 qualifying games in total.
• If a performance exceeds the norm score sufficiently, that excess, called overscoring, can reduce the effective number of games required.
• Certain championship results award the title directly; the 2026 rules include places one through three in the World Correspondence Chess Ladies' Championship Final.

A norm is a regulated performance inside an eligible title tournament, not a single win or an isolated rating number; a rating is a numerical estimate of playing strength. The required score, opponent count, and other conditions are determined by the ICCF title rules applying to that event.
