What Your AS9100 Auditor Knows That You Don’t (Yet): The Case for Training In-House

It’s a common story: an AS9100-certified organization sits through an audit debrief that ends with a nonconformity nobody saw coming. It’s not because the evidence wasn’t there. It’s often because nobody on the team was looking at it in the same way the auditor was. 

The Gap Between “We Have a Process” and “We Can Prove It” 

Internal teams tend to think in terms of whether a procedure exists. Good auditors think in terms of whether the objective evidence demonstrates that the procedure actually gets followed, consistently, across the organization. That’s a different mindset, and it’s not something most quality engineers pick up just by living inside their own QMS every day. 

What Auditor Training Actually Covers 

AATT’s online component includes scenarios built specifically to test how well you can evaluate audit evidence, not just recite standard requirements. The instructor-led week builds on that with group workshops and individually assessed case studies, working through realistic audit situations using the same 9101 forms a certification body auditor uses. It’s genuinely the same foundation your third-party auditor went through. 

Where This Shows Up During a Real Audit 

  • Reading documentation the way an outside auditor will, rather than the way it was written.
  • Structuring interview questions that surface real evidence instead of a rehearsed answer.
  • Recognizing where nonconformities tend to get written, and documenting findings the way a certification body auditor would.

Why This Is Worth Doing In-House 

A lot of organizations bring in outside consultants to help prep for each audit cycle. That may help, but the knowledge leaves when the consultant’s contract ends. Training someone on your own team means that same audit fluency stays in the building, ready for this audit and the next one.  

Still Need Lead Auditor Training First? 

The AATT assumes auditors have completed Lead Auditor training as a prerequisite. If that’s the missing piece for someone on your team, Plexus also runs a 5-day AATT and Lead Auditor bundle the same week as the standard AATT session, so both can be knocked out in a single trip.
