An International Master norm is a title performance of at least 2450 against opponents averaging at least 2230.

An International Master norm is a title performance of at least 2450 against opponents averaging at least 2230, achieved in an event that satisfies the title rules on administration and opponent mix.

An [International Master](https://georgelichess.com/glossary/international-master.md) norm follows the same template as a [Grandmaster norm](https://georgelichess.com/glossary/grandmaster-norm.md) with lower numbers. The [performance rating](https://georgelichess.com/glossary/rating-performance.md) must be at least 2450, the opponents must average at least 2230, and you must score at least 35 percent over at least nine games. Titles matter as well: half the field must carry one, and the IMs and GMs among the opponents must number a third of them, never fewer than three.

The opponent [rating floor](https://georgelichess.com/glossary/rating-floor.md) is 2050, applied only to the lowest rated opponent, and unrated opponents count as 1400. Two federations other than your own must appear, with the usual caps on opponents from a single federation. The event must also meet the administrative rules: registration on the FIDE server at least 30 days ahead, a chief [arbiter](https://georgelichess.com/glossary/arbiter.md) who holds an International Arbiter or FIDE Arbiter title, and no more than two rounds a day.

One norm leaves you short, because the title also asks for 27 games across the norms and a peak rating of 2400. See norm, Grandmaster norm and International Master.

Also called: IM norm.

It sits close to [Norm tournament](https://georgelichess.com/glossary/norm-tournament.md). A norm tournament is an event organized with the conditions that let players score a title norm, such as the right mix of opponents, enough rounds and a qualified arbiter.
