What to Expect from an ISO 42001 Audit

Most organizations I talk to understand why ISO 42001 matters. Where things get fuzzy is the audit itself. What does it actually involve? Who shows up? What happens if something isn't right? I get some version of these questions pretty regularly, so here's a straightforward breakdown.

There Are Three Types of Audits

A first-party audit is internal. Your own team reviews your AI management system against the standard. This should be happening regularly as part of running your program, not just as a warmup before certification.

A second-party audit is when a customer or partner audits your AI governance practices directly, usually as part of vendor due diligence. These are getting more common as larger enterprises start requiring ISO 42001 compliance from their suppliers.

A third-party audit is what most people mean when they say certification. An accredited body comes in, reviews your documentation and practices against the standard clause by clause, and decides whether to issue the certificate.

Certification Happens in Two Stages

Stage 1 is a documentation review. The auditor is not showing up to interrogate anyone yet. They are checking whether your AI management system is designed correctly on paper. Scope statement, risk assessment methodology, policies, objectives. Think of it as a readiness check. If something is off, they will flag it before Stage 2 so you have time to fix it.

Stage 2 is the full assessment. This is where the auditor checks whether what you documented in Stage 1 is actually happening. They will interview people, pull records, and look at whether your AI governance program is genuinely operational or just exists on paper. There is a real difference between the two, and auditors can tell.

What Auditors Are Actually Checking

Auditors are not trying to catch you out. They want to see a functioning system, not a perfect one. Here is what they focus on.

Scope and context. Can you clearly explain what AI systems are in scope, what your organization's AI objectives are, and who your relevant stakeholders are? Vague answers here tend to raise flags early.

Leadership commitment. Is AI governance actually supported at the top, or is it a compliance checkbox nobody senior cares about? Auditors look for real evidence: signed policies, meeting records, defined accountability. Not just a slide deck.

Risk assessment. Do you have a documented, repeatable process for identifying and assessing AI-related risks? Not just a list of risks, an actual methodology that gets applied consistently.

Controls. For the risks you have identified, what are you doing about them? Are those controls documented, implemented, and working?

Monitoring. How do you know your system is performing? Auditors want to see metrics, review cycles, and evidence that someone is actually paying attention to outcomes.

Internal audits and management reviews. These are mandatory requirements. Have you audited your own system? Has leadership formally reviewed it? Auditors will ask for records, so if it happened but was never documented, it effectively did not happen.

When the Auditor Finds Something

Findings come as nonconformities or observations. A major nonconformity has to be resolved before certification is issued. A minor nonconformity can be addressed within an agreed timeframe after the fact. Neither one means you failed. First-time certifications almost always come with some findings. That is normal.

An observation is softer. The auditor is flagging something that is not a problem yet but could become one. Technically you are not required to act on it. Practically, you should.

The Most Common Reason Organizations Are Not Ready

It is rarely that their AI practices are bad. Usually it is that nobody wrote anything down. A lot of companies have informal AI governance happening across teams but no consistent process and no evidence trail. That gap is fixable, but it takes time to do properly.

The other thing I see frequently is organizations trying to certify everything at once instead of starting with a manageable scope. Narrowing your initial scope is not cutting corners. It is the smarter way to get to certification without burning out your team in the process.
