What are and which is highest IM or NM or FM or CM?

I think NM is a title given by national federations, so it would be parallel to CM. Here it doesn't exist.

NM is the odd one out in that list because it's awarded by the USCF, whilst the others are awarded by FIDE. So you could be a NM but not a CM, or a CM but not an NM. One isn't higher than the other, they are based on different rating systems.

Yup!

This is correct, but generally speaking, CM requires 2200 FIDE, which seems to be somewhat more difficult to obtain than the 2200 national rating required for NM.
I am an NM ( of 2 countries ) and over 2200 FIDE which entitles me to the CM title as well . The titles NM and CM are roughly equivalent , I assure you .

Just out of interest, why did you claim the NM but not the CM? Is CM hardly worth having?

Aha. Just looked it up, 50 euros. Surely you would get that back with interest in the form of discounted entry into tournaments though?

Fair enough. I'll probably still claim it if I ever get to 2200 though, just for the sake of having a title and feeling big and important
I know GM. but what are others like NM, FM, CM and whose is rated higher? thanks!
