I've been teaching AI governance for a while and writing about ISO/IEC 42001, so I figured the auditor course would mostly be review. It wasn't. Sharing this because I couldn't find much firsthand info before signing up.
What I expected: memorize clauses 4 through 10, memorize Annex A controls, pass.
What it actually was: scenario judgment. You get a situation and have to decide whether it's a nonconformity, an observation, or an opportunity for improvement. Then justify it. Which clause, which requirement, what evidence is missing.
That distinction turned out to be the whole course. Explaining a standard and auditing against it are different skills. When you explain, you describe what the clause says. When you audit, you look at a document and ask whether it constitutes objective evidence of conformity. Completely different mental motion.
A few things worth knowing if you're considering it:
The AI Impact Assessment requirement in clause 6 has no equivalent in ISO 27001 or 9001. Organizations have to assess and document the effects their AI systems have on individuals and society. Most companies I've worked with have nothing here. It's the single most common gap.
Annex A data controls are brutal in practice. Provenance, quality, bias, preparation methods for training data. Anyone who deployed a generative AI tool without documenting where the data came from will fail this.
Your organizational role determines your requirements. Developer, provider, or user. A company that only uses third-party AI has a very different scope than one training models. A lot of people misclassify themselves at the start and build the wrong scope.
Third-party management is where most AI-using orgs are exposed. If you're running your business on external APIs and have no supplier control procedure, that's a finding.
Open question for anyone here who's done actual 42001 audits: how are you handling evidence for impact assessment? The standard says assess, it doesn't prescribe a format. Curious what's holding up in real certification audits versus what auditors are pushing back on.
Happy to answer questions about the course structure or exam format if anyone's on the fence.
