Currently you need to have an actual FIDE rating of 2500 or higher, in addition you need norms. A norm comes from performing at 2600 rating equivalent or better in an international grandmaster tournament. To be an international grandmaster tournament, there are some complicated rules, for average player rating, for number of players who are already grandmasters, for players having to be from several different countries etc. The norms have to be from at least two tournaments, but usually three, totalling (i think) at least 25 games. [ There are also several special ways to get the GM title which don't depend on ratings and norms. ] > Second, someone suggested data giving the FIDE rating which present day GMs >had at the time the title was awarded would be useful in determining whether the >programs were performing at GM level.

It's not unusual for players to get the three GM norms when their rating is only 2470 or so, and then they get the title as soon as their rating creeps up to 2500. So 2500 is quite a common rating for new GMs. Some players don't get a chance to play in GM tournaments until they are already very good and very highly rated. A few years back there was a player with a 2680 rating when they became GM. But 2500 to 2550 would be the normal rating range for new GMs.
