ExploreAbout this exam
The PECB Certified ISO/IEC 42001 Lead Auditor credential is awarded by PECB to professionals who pass the ISO/IEC 42001 Lead Auditor exam and then satisfy the experience requirements attached to the credential they apply for. It attests the ability to audit an artificial intelligence management system (AIMS) against ISO/IEC 42001 by applying widely recognised audit principles, procedures and techniques, in line with ISO/IEC 17021-1 requirements and ISO 19011 guidelines. The training is aimed at internal and external auditors who want to specialise in AIMS auditing, managers and consultants who need to master the AIMS audit process, people responsible for maintaining conformity with AIMS requirements, expert AI advisers, and professionals involved in developing AI solutions or designing AI system architecture. It runs over five days: the first four cover AIMS fundamentals and ISO/IEC 42001, audit principles plus preparation and initiation, on-site activities, and closing the audit, with the certification exam on Day 5. Lectures are reinforced with case-study examples, essay-type exercises and multiple-choice quizzes, many scenario-based to mirror the exam style. Participants receive material of over 450 pages and, on attendance, an attestation worth 31 CPD credits.
What you'll study
About ISO 42001 Lead Auditor preparation
What does the exam actually cover?
The exam meets the requirements of the PECB Examination and Certification Program and covers seven competency domains: fundamental principles and concepts of an AI management system; AI management system requirements; fundamental audit concepts and principles; preparing, conducting and closing an ISO/IEC 42001 audit; and managing an ISO/IEC 42001 audit program. Expect to apply these domains to situations, not just recall clause text.
How many questions are on the exam, how long is it, and what is the pass mark?
The PECB course page does not publish the number of exam items, the duration or the passing score. 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 you can plan your pace and test-day logistics.
Do I need audit or AI experience just to sit the exam?
No. The main requirement for participating in the training course is a fundamental understanding of ISO/IEC 42001 and of AI principles and concepts. The exam itself is taken after the course. Professional experience only becomes relevant later, when you apply for a specific PECB ISO/IEC 42001 Auditor credential.
What experience do I need for each credential after passing?
Provisional Auditor requires no experience beyond the exam and signing the PECB Code of Ethics. Auditor requires two years of work experience, one year of it in AI, and 200 hours of audit activities. Lead Auditor requires five years, two of them in AI, and 300 audit hours. Senior Lead Auditor requires ten years, seven in AI, and 1,000 audit hours.
When is the exam taken?
The exam is the fifth day of the course. Days 1 to 4 cover the AI management system and ISO/IEC 42001, audit principles with audit preparation and initiation, on-site audit activities, and closing the audit. Sitting the exam directly after the four teaching days keeps the material fresh.
What happens if I fail the exam?
Candidates who fail may retake the exam within 12 months following the initial attempt, free of charge. The published page states the 12-month window and the free retake; it does not describe further conditions, so confirm attempt rules in the PECB Examination Rules and Policies before relying on them.
What is included in the course price?
Certification and examination fees are included in the price of the training course, so the exam is not billed separately. Participants also receive training material containing over 450 pages of explanatory information, examples, best practices, exercises and quizzes, and attendees are issued an attestation of course completion worth 31 CPD credits.
How should I sequence my study during the week?
Follow the course agenda. Spend the most time on Domain 2, interpreting ISO/IEC 42001 requirements from an auditor's viewpoint, because the later audit domains depend on it. Rehearse the essay-type exercises and scenario-based quizzes under time pressure, since the course uses them specifically to replicate the certification exam format.
How difficult is the exam, and where do candidates typically lose marks?
No pass rate is published, so treat difficulty claims with caution. The course design signals the risk area: scenario-based questions that replicate the exam reward candidates who can evaluate conformity and justify findings, while those who only memorise definitions struggle. Practise writing short, evidence-based conclusions and nonconformity statements before exam day.
