Why Is the ISO 45001 Lead Auditor Course 40 Hours?

What the 40 live hours of the CQI IRCA ISO 45001 Lead Auditor course are for: the skills a Lead Auditor must build, why they need practice and how the hours connect to the exam.

3FOLD Training is a CQI IRCA Approved Training Partner (ATP 6039853) · Licensed by KHDA, Dubai

  3. Which skills take the most practice?
  4. Why can’t it be compressed?

  10. FAQs

Forty hours can look long when you first see it on a course page. It is worth understanding why, because the length is a design choice, not padding. A Lead Auditor does not just know a standard; they plan an audit, lead a team, gather evidence, judge it fairly and report clearly. Those are skills, and skills are learned by doing them with feedback. This guide explains what the 40 hours of the CQI (Chartered Quality Institute) and IRCA (International Register of Certificated Auditors) ISO 45001:2018 Lead Auditor course (PR357) are for. We do not print batch dates, and CQI and IRCA set the course requirements, so confirm the current rules with them.

Quick answer

The ISO 45001 Lead Auditor course is 40 hours because it has to teach the ISO 45001:2018 requirements and also build the practical skills of leading an audit: planning, interviewing, sampling evidence, writing findings and reporting. According to the 3FOLD Training course page, those hours are live online Virtual Instructor Led Training (VILT), with exercises, trainer feedback and mock exam preparation. Confirm the requirement with CQI and IRCA.

Why is the ISO 45001 Lead Auditor course 40 hours?

Because it teaches both what the standard says and how to audit against it.

A short course could cover the clauses. A Lead Auditor course has a harder job: after it, you should be able to take part in leading a management system audit. That needs time for explanation, time for practice and time for feedback. For the practical timeline around the course, see our guide on how long the ISO 45001 Lead Auditor course is.

What must a Lead Auditor be able to do by the end of the course?

Plan, lead, evidence, judge and report.

  1. Plan: set objectives and scope, and prepare an audit plan.
  2. Lead: run the opening and closing meetings and guide an audit team.
  3. Gather evidence: interview, observe and review records, then sample sensibly.
  4. Judge: compare evidence with the criteria and decide what is a finding.
  5. Report: write clear findings and conclusions, and follow up.

Our guide to how an ISO 45001 audit works from start to finish follows the same sequence.

Which Lead Auditor skills take the most practice time?

The skills that cannot be learned by reading.

SkillWhy it needs practice
InterviewingGood questions and listening improve with feedback
Judging evidenceYou learn to tell facts from opinion by working examples
Writing findingsClear, fair wording takes repeated drafting
Leading a teamGroup exercises show how roles work in practice
ReportingConclusions must match the evidence

Reading about an audit is not the same as running one.

Why can’t the course be compressed into a few hours?

Because skills need repetition and feedback, which take time.

You can summarize ISO 45001:2018 quickly. You cannot summarize the experience of conducting an interview, being challenged on a finding or writing a report that stands up. Each exercise has to be done, discussed and corrected. Squeeze that into fewer hours and the practice is the first thing to disappear. That is also why recordings alone are a weak substitute for live hours, so check how many hours are live and confirm the arrangement with CQI and IRCA. Our ISO 45001 audit interviews and evidence guide shows one skill that benefits from practice.

What is in the 40 hours besides teaching?

Exercises, a case study, feedback and exam preparation.

  • Instruction. The ISO 45001:2018 requirements and the audit process.
  • Exercises. Planning, interviewing and reporting practice with other learners.
  • A case study. A realistic situation you audit together.
  • Trainer feedback. Comments on your activities.
  • Exam preparation. Mock exams on the learning management system (LMS).

Our ISO 45001 audit plan and checklist guide is a good example of the planning work you practice.

How do the 40 hours connect to the exam?

The exam tests the same five areas the course builds.

According to the CQI and IRCA online exams guide for learners (2024), the exam has 40 questions in 1 hour 45 minutes, across five domains: concepts and principles of management standards and systems, audit concepts and auditor responsibilities, planning the audit, conducting the audit, and reporting and closing out the audit. The exam is open book and scenario based, so it rewards audit judgment, which is exactly what the practice hours build. Our guide to how many questions and marks are in the ISO 45001 Lead Auditor exam sets out the format, and our best tips to pass the CQI IRCA ISO 45001 Lead Auditor exam show how to use what you learn.

What should you check if a provider offers fewer hours?

Whether the course is CQI IRCA certified, and how many hours are live.

  1. Ask for the course ID (PR357 for ISO 45001) and the provider’s approval number.
  2. Confirm both with CQI and IRCA, not only with the provider.
  3. Ask how many hours are live with an instructor, and how many are recorded.
  4. Ask what has been removed, such as exercises or the case study.
  5. Ask which certificate you receive. Only a Certificate of Achievement can support an IRCA grade application.

Our guide to CQI IRCA certified training courses explains how approval works, and our guide to the eligibility criteria for the ISO 45001 Lead Auditor course helps you check you are ready.

Course design simulation: choose the best auditor action

For practice only. Read each situation and choose the best response. These scenarios were written by 3FOLD Training and are not real exam questions or legal advice.

Situation 1. A learner says 40 hours is too long because the standard can be read in a day. What is the best reply?
Model answer: Reading the standard is only part of the job. The hours build the skills of leading an audit.
Situation 2. A provider offers the same certificate in a fraction of the hours. What should you check first?
Model answer: Ask for the course ID and approval number, confirm them with CQI and IRCA, and ask what was cut.
Situation 3. Which of these is hardest to learn from reading alone?
Model answer: Interviewing and judging evidence improve through exercises and feedback.
Situation 4. A learner skips the live exercises and plans to rely on recordings. What is the main risk?
Model answer: Live exercises give you practice and feedback. Check the arrangement for recordings with your provider and CQI and IRCA.
Situation 5. How do the course hours help with the open-book exam?
Model answer: The exam is scenario based. Practice with scenarios builds the judgment it tests.

1 scenario answered: 1 of 1 correct

Preloaded example: Situation 1 is already answered. Check live hours, certification and what practice is included.

Frequently asked questions

Why is the ISO 45001 Lead Auditor course 40 hours?

Because it teaches the ISO 45001:2018 requirements and also builds the practical skills of leading an audit, such as planning, interviewing, gathering evidence, writing findings and reporting. According to the 3FOLD Training course page, those hours are live online VILT. Confirm the requirement with CQI and IRCA.

What does a Lead Auditor learn in the 40 hours of the ISO 45001 course?

You learn the ISO 45001 requirements and the audit process, then practice planning, leading, evidencing, judging and reporting through exercises, a case study and trainer feedback. Mock exam preparation sits alongside the live days.

Can the ISO 45001 Lead Auditor course be shorter than 40 hours?

Ask the provider and CQI and IRCA. A CQI IRCA certified course has its own requirements, so a much shorter course under the same certificate needs an explanation. Ask for the course ID, the approval number and the number of live hours.

Are the 40 hours of ISO 45001 Lead Auditor training all live?

According to the 3FOLD Training course page, the ISO 45001 Lead Auditor course is delivered as 40 hours of live online Virtual Instructor Led Training (VILT). Always ask any provider how many hours are live and how many are recorded.

Why does the ISO 45001 Lead Auditor course include practice exercises?

Because audit skills such as interviewing, judging evidence and writing findings are learned by doing them and getting feedback, not by reading. Exercises and a case study let you rehearse the skills the exam and the role require.

How do the 40 hours prepare me for the ISO 45001 Lead Auditor exam?

The CQI and IRCA exam has 40 questions in 1 hour 45 minutes, is open book and is scenario based. The course hours build the audit judgment those scenarios test, and the course includes an exam study guide and two mock exams, according to the 3FOLD Training course page.

Is 40 hours enough to pass the ISO 45001 Lead Auditor exam?

The live hours are the core of the preparation, but you should also plan your own revision and mock exam practice. No provider can promise a pass, because CQI and IRCA examine and certify.

Does 3FOLD Training teach the full 40 hours of the ISO 45001 Lead Auditor course live?

Yes. According to the 3FOLD Training course page, the ISO 45001 Lead Auditor course (PR357) is 40 hours of live online VILT, with an exam study guide, two mock exams, trainer feedback and the first CQI and IRCA attempt. We prepare you for the exam; CQI and IRCA examine and certify.
