Which ISO/IEC 42001 clauses would fail an audit today?
Rate the 27 requirements in clauses 4 to 10 on a five-level maturity scale, decide each of the 38 Annex A controls for a draft Statement of Applicability, and see a score by clause, the gaps an auditor would likely grade major or minor, and whether you are ready for Stage 1 or Stage 2. Nothing leaves your browser.

How the rating works
The AIMS readiness checklist asks whether each piece of evidence exists. This calculator asks how far each requirement has got, because an auditor grades the distance between a written procedure and the records that prove it runs. Rate every requirement against the scale below. If you are unsure between two levels, take the lower one: that is the one an auditor will find.
Five levels, and the two an auditor gates on
- 0Not startedNothing exists yet, or only in someone’s head.
- 1PlannedIntent is written down (a plan, a draft, a slide), but nothing is approved or operating.
- 2DocumentedAn approved procedure or record exists, but there are no operating records yet to show it runs.
- 3OperatingDated records from the last twelve months show it running as documented.
- 4Evidenced and reviewedOperating, sampled by internal audit and considered at management review.
Stage 1 floor: the core documents must reach level 2. Stage 2 floor: internal audit and management review must reach level 3.
Stage 1 needs the core documents at level 2 or above (4.3, 5.2, 6.1.2, 6.1.3, 6.1.4, 6.2) and a complete Statement of Applicability. Stage 2 needs a full cycle of internal audit (9.2) and management review (9.3) at level 3 or above, no likely major nonconformity, and every applicable control implemented. Grades here are indicative: a certification body grades on what it finds in sampled records.
Next: not ISO/IEC 27001 certified? Leave the box unticked and start at Step 1. Rate every requirement, then decide each Annex A control in Step 2.
Next: keep going through Step 1 and Step 2. ISO/IEC 27001 certification does not certify an AI management system, so every requirement still needs a rating. What changes is the effort. Each requirement now carries a tag:
- Extend your ISMS process 21 requirements. Your ISMS process already exists; rate how far it covers AI systems today.
- Adapt your ISMS method 4 requirements. The method carries over; the AI risk criteria and treatments are new work.
- New to you 2 requirements. No ISMS counterpart. Expect these to be your main gaps.
In Step 2, 16 Annex A controls show their ISO/IEC 27001 counterpart, so you can extend that evidence. Start at Step 1
0 of 27 requirements rated · 0 of 38 controls decided
Clause 6.1.3 asks for a justification for every control, included or excluded. An exclusion with no reason is the first thing a Stage 1 auditor will raise.

What your ISO/IEC 27001 system carries over
To check the evidence under each requirement question by question, use the ISO 42001 AIMS Readiness Checklist. To see how the controls sit in an agentic retrieval pipeline, read the Governed Agentic RAG reference architecture, which maps each component to a clause or Annex A control. If the system may also fall under the EU AI Act, use the EU AI Act Risk Classifier.

The question I am asked most before a 42001 assessment is how close we are, and a percentage of boxes ticked never answers it. What answers it is the distance between a procedure that has been approved and the records that show it running, because that distance is what an auditor grades. Rate yourself at the lower of two levels whenever you hesitate. The gaps that matter at Stage 1 are almost always the same few documents, and the one that matters at Stage 2 is whether internal audit and management review have actually run once.
