ExploreAbout this exam
The PECB Certified ISO 45001 Lead Auditor credential targets professionals who plan, lead, and report on occupational health and safety management system (OH&S MS) audits against ISO 45001 - described by PECB as the first global OH&S MS standard, replacing OHSAS 18001. The training course develops the skillset needed to audit an OH&S MS using widely recognized audit principles, procedures, and methods, aligned with the auditing guidelines in ISO 19011 and the certification process in ISO/IEC 17021-1. The exam is held on day 5 of the five-day course and spans seven competency domains: OH&S MS fundamentals, ISO 45001 requirements in Clauses 4 to 10, fundamental audit concepts and principles, preparing, conducting, and closing an ISO 45001 audit, and managing an audit program. Passing the exam lets you apply for the credential; PECB states that an IAS certified, internationally recognized certificate validates your ability to audit an OH&S MS. The course suits auditors, managers and consultants, internal auditors responsible for conformity to ISO 45001, technical experts, and OH&S advisers. PECB notes that participants receive over 450 pages of instructional materials and 31 CPD credits, and that certification and examination fees are included in the course price.
What you'll study
About ISO 45001 LA preparation
What does the exam cover?
PECB lists seven competency domains: fundamental principles and concepts of an OH&S MS; ISO 45001 requirements for an OH&S MS, Clauses 4 to 10; fundamental audit concepts and principles; preparing for an ISO 45001 audit; conducting an ISO 45001 audit; closing an ISO 45001 audit; and managing an ISO 45001 audit program.
How many questions are on the exam, and how long does it take?
PECB does not publish the item count or duration on the course page; it directs candidates to the List of PECB Exams and the Examination Rules and Policies for exam type, available languages, and other details. Check those documents before you book so your timing expectations are based on current official information rather than hearsay.
When is the exam taken?
It is the final element of the five-day course: Day 1 covers OH&S MS and ISO 45001, Day 2 covers audit principles plus audit preparation and initiation, Day 3 covers on-site audit activities, Day 4 covers closing the audit, and Day 5 is the certification exam.
What happens if I fail?
PECB states that in case of exam failure you can retake the exam within 12 months free of charge. Plan your retake while the case-study exercises and quiz feedback from the course are still fresh, and use the gap to revisit the domain where your weakest answers clustered.
Do I need audit experience before sitting the exam?
The course prerequisites are a fundamental understanding of ISO 45001 and a comprehensive knowledge of audit principles. Experience only enters when you apply for a credential: Provisional Auditor requires none; Auditor requires two years of work experience with one year in OH&S management plus 200 hours of audit activities; Lead Auditor requires five years with two in OH&S management plus 300 hours.
Which standards underpin the audit techniques taught?
PECB states the course prepares you to plan and carry out an OH&S MS audit in compliance with the guidelines for auditing management systems in ISO 19011 and the certification process described in ISO/IEC 17021-1. Expect questions that frame auditor behaviour and audit programme management in those terms.
How should I sequence my study?
Follow the competency domains in order. Secure OH&S MS fundamentals and ISO 45001 Clauses 4 to 10 first, then audit principles, then the prepare–conduct–close sequence, and finish with audit programme management. Practise drafting nonconformity reports and reviewing documented information, since these are the activities the course exercises drill.
Are the training materials and CPD credits included?
Yes. PECB states it will provide over 450 pages of instructional materials containing explanations, guidance, and practical examples, and that a participation certificate of 31 CPD (Continuing Professional Development) credits will be issued. Certification and examination fees are also included in the price of the training course.
How often must the credential be maintained?
The course page does not state a validity period. PECB says maintenance is governed by its Certification Rules and Policies and Certification Maintenance pages, so confirm the current requirements there rather than assuming a fixed renewal cycle. Requirements can be revised, and those pages are the authoritative source.
What is the most common way candidates lose marks?
Two patterns dominate. First, treating ISO 45001 clauses as a checklist to recite rather than as evidence to evaluate from an auditor's perspective. Second, weak audit-process discipline - vague nonconformity reports, unsupported findings, or confusing correction with root-cause analysis. The course quizzes simulate the exam, so use them to expose these habits early.
