I am of the idea that in order to be a good auditor (effective anyway), you need to know as much as possible what you are auditing against. I started my career with the 5 day lead auditor course and it wasn't as smooth to go through audits while trying to understand ISO. I must say that I did have the opportunity of shadowing experienced and corporate auditors and that was a great help.
UPDATE!! On the one-day ISO9000:2008 training for to be auditors:
We had the expert of the local State university whom takes care of training ISO/auditors, and performs third party audits state wide. It was personally a great experience for me as I got to ask a lot of specific questions I had, while transitioning in my head from TS16949 (which I last experience at my last job before plant closure) and now with the 2008 version.
For the rest of the team, the 3 auditors to be and the QM, I believe it was a very good experience also. Main reason, our trainer didn't use a power point, but just the standard. She had us read each section taking turns, but the point: we got to discuss how that applied to our particular company, she pointed out to possible holes, or whether what we had in place was fair to satisfy the standard. In short, it was a combination of digesting the standard and evaluating our situation all in one.
Thanks everyone for your comments and tips, very valuable!
