Be careful, not always true what you are introduced to...
It happened to me many years before. We made a training for supervisors - all we keep listed with valid status reports of certificates.
One applied for a project with same Ex certificate. Client checked via contacting us. It has turned out to be fake...
Noone is happy...

Trust in a system which is traceable.
Keep up good work!
