What does the ISO 45001 Lead Auditor exam test?

It tests your knowledge of ISO 45001:2018 and your ability to apply the audit method.

A Lead Auditor needs more than definitions. You must know what the standard requires, plan and carry out an audit, judge evidence and report findings clearly. The exam therefore mixes questions about the standard with questions about what an auditor should do in a situation. CQI and IRCA set the exam rules, including the format and the pass requirements, so check the current details on the 3FOLD Training ISO 45001 Lead Auditor course page before you sit it. Our guide to how an ISO 45001 audit works from start to finish shows the audit steps in order.

What types of questions should you expect?

Expect knowledge questions, scenario questions, audit method questions and reporting questions.

The table shows each type, what it checks and an example of the thinking it needs. The examples are written by 3FOLD Training and are not real exam questions.

The exam rewards the learner who asks what the evidence shows, not the learner who guesses.

What do sample answers look like?

A good answer names the requirement, says what evidence you need and chooses the next action.

These five practice-style situations show the reasoning. Try to answer each one before you read the model answer.

1. The OH&S policy was signed by the OH&S manager only. Model answer: check that top management established the policy and takes accountability for it, and ask how it was communicated and reviewed. Our guide to the role of top management in ISO 45001 explains the requirement.
2. Personal protective equipment was chosen for a noise hazard with no other option considered. Model answer: ask how the organization considered the hierarchy of controls, starting with elimination, and look for the records. See our guide to auditing the hierarchy of controls.
3. A worker who reported a near miss says they were told off. Model answer: ask how the organization protects workers from reprisals when they report, and check the reporting process and records. Do not conclude from one comment alone.
4. The organization has three-year-old objectives with no owner. Model answer: ask how objectives are planned, owned, monitored and updated. See our guide to auditing OH&S objectives.
5. You are unsure whether a gap is a nonconformity or an observation. Model answer: a nonconformity is the non-fulfilment of a requirement, so identify the requirement and the evidence first. If no requirement is missed, it may be an observation.

How do you answer a scenario question?

Read carefully, find the requirement, decide what evidence you need and choose the best next action.

1. Read the situation twice and note who said what, and what is actually known.
2. Find the requirement in ISO 45001:2018 that the situation relates to.
3. Decide what evidence you need, such as a record, an observation or an interview.
4. Choose the best next action, usually to gather evidence before you judge.
5. Avoid jumping to a finding when the evidence is thin or comes from one source.

Our guide to how to interview workers in an ISO 45001 audit shows how comments become evidence.

How should you prepare for the exam?

Learn the terms, practice scenarios and review every mistake.

• Learn the key terms. Hazard, risk, incident, worker, nonconformity and corrective action come up again and again. Test yourself with our ISO 45001 MCQ questions and answers.
• Practice scenarios. Work through our audit guides, each with a short simulation.
• Review your mistakes. Note why a wrong answer was wrong, not only what was right.
• Read the standard. Use the clauses as your reference, not a summary.
• Check the format. Read the current exam details on the course page before the exam.

What should you revise before the exam?

Revise the areas where you lost marks in practice, and the audit method.

• Worker participation. Read our guide to worker consultation and participation in ISO 45001.
• Performance evaluation. Read our guides to monitoring and measurement and evaluation of compliance.
• Audit planning. Read our guide to the ISO 45001 audit plan and checklist and the documents required for an ISO 45001 audit.
• The role. Compare internal auditor and lead auditor roles.

Always check the exact wording in the standard and confirm the exam rules with CQI and IRCA.
