Are you wondering if someone is really a Certified Facility Manager or maybe he was just pretending?
It's very easy. You can verify that if his name is on the IFMA CFM Credential Registry
The registry looks like the picture below. All you need to know is their name and viola, in one click you'll know if he is certified or not.
If you're an HR or you're simply a student wondering if your instructor in CFM is a Certified Facility Manager or not, you can check through the link given above.
And if they said that their name wasn't there because they just recently took the exam, don't believe in that because the registry is updated with just a few hours after they took and pass the CFM exam.
