Rich, I have been informed about this requirement by 2 of the CB operating in my country. I believe it is from the same source (same trainer different session of the training). I posted this question to this forum and seems like most of the forum members do not agree. However I have also sent enquiry message to the IAOB and the reply as below: -
***Referring to the clause you mentioned, we can only say that internal auditor must be trained by a qualified internal audit course. At this moment no IATF requirements about training provider are issued.****
I actually required a better definition what is "qualified internal audit course" and waiting for reply. As of this moment, there is no sanctioned interpretation is issued.
