Arena Candidate Master

Arena Candidate Master, abbreviated ACM, has the lowest rating threshold among FIDE Online Arena's lower-rating-band titles, associated with the International Chess Federation, FIDE. A rating is a number that summarizes estimated playing strength from results. ACM belongs to the online system and is not the same title as over-the-board Candidate Master, or CM.

The ACM rating requirement is 1100 or higher, maintained for a minimum number of games. Under the platform's current process, only rated tournament games count toward title progress. Receiving the recognized title also requires a PRO account and a connected FIDE ID, the unique number identifying a registered player in FIDE's database.

• 50 rapid games.
• 100 blitz games.
• 150 bullet games.

Above ACM are Arena FIDE Master and Arena International Master, followed by Arena Grandmaster. The ladder raises the rating threshold while keeping the same basic requirement of sustaining it through enough qualifying play.
