What prerequisites should you check before enrolling?
Knowledge of the standard you will audit, some first-hand audit practice, command of the exam language and a week that is genuinely free. A Lead Auditor course assumes that the requirements of the standard are already known: it teaches you to audit them.
The exact prerequisites are specific to each certified course: ask the training provider for them in writing before enrolling.
The table lets you take stock on your own, before asking for a quote.
Prerequisite | How to check it yourself | If it is not there yet |
|---|---|---|
Know the requirements of the standard | Explain each clause without notes and illustrate it with an example from your company | First take a requirements course, for example on ISO 9001:2026 or ISO 45001:2018 |
Understand the common structure of ISO standards | Place context, leadership, planning, support, operation, performance evaluation and improvement | Read the standard with a map of its clauses |
Have experienced audits | Have been audited, or have conducted internal audits | Take an internal auditor course and join an audit as part of a pair |
Master the exam language | Read a technical text and write against the clock in that language | Choose a session in your working language |
For food safety: know HACCP | Explain the principles, the difference between CCPs and OPRPs, validation | Take a HACCP course; FSSC 22000 v7 requires 16 hours of it from its auditors |
Have the week available | Block the days, with no on-call duty or production meetings | Postpone the session rather than follow half of it |
The choice of standard comes before everything else. Our guide to the IRCA Lead Auditor course in Africa explains how to make that choice and how to check that a course really is certified.
How do you organise your revision over four weeks?
By devoting each week to one subject: the standard, the audit method, practice on your site, then logistics. Two or three sessions a week are enough for a professional who already works with the standard.
Week | Objective | Activities | What you have at the end |
|---|---|---|---|
W-4 | Master the standard | Read the full text in the current edition; mark every “shall”; link each clause to a process in your company | A map of the clauses annotated with your own examples |
W-3 | Understand the method | Read ISO 19011:2026: audit principles, audit programme, conducting an audit, auditor competence; learn the vocabulary (criteria, evidence, finding, conclusion) | A one-page personal glossary |
W-2 | Practise in the field | Audit a process on your site with a checklist; write five complete findings; have them reviewed by an experienced auditor | Five findings written and corrected |
W-1 | Consolidate and get organised | Review the map, the glossary and the findings; prepare the documents requested; sort out logistics | A ready file and a week cleared |
Three tips for these four weeks:
- Work on the right edition. ISO 9001:2026 was published on 16 September 2026 and ISO 14001:2026 in April 2026; ISO 45001:2018 and ISO 22000:2018 remain in force. Check that the edition you revise on is the one the course covers.
- Read ISO 19011 in its fourth edition. Published on 27 May 2026 according to the ISO page, it replaces the 2018 edition. The changes that matter to an auditor are summarised in our article on Lead Auditor requirements for 2027.
- Start from your own processes. A requirement understood in your own workshop, warehouse or construction site sticks better than a textbook example.
How do you get the most out of the course days?
By treating them like an audit: take part, take on roles, take notes, and review each evening what you have learned. The continuous assessment covers what you do during the course, not just what you know.
- Take the team leader role whenever a role-play allows it: it is the role the course assesses.
- Work with the standard open and learn to find a clause quickly.
- Write your findings yourself during team exercises, then compare them with the trainer’s.
- Note your weak points at the end of each day and review them in the evening, in thirty minutes.
- Bring questions from the field: a real case from your site, anonymised, is often worth more than a theoretical exercise.
How do you prepare for the final exam?
By practising application, not recitation. A Lead Auditor must be able to recognise the audit principle at stake, decide whether a situation is a nonconformity and against which requirement, write a defensible finding and organise an audit within a given time.
The format, duration, pass mark and documents allowed are specific to each certified course: ask the training provider for them before the course, so that you practise under the same conditions.
Skill expected of a Lead Auditor | Common mistake | Good practice |
|---|---|---|
Qualify a situation | Seeing a nonconformity everywhere | Look for the precise requirement before concluding |
Write a finding | “The documentation system is not controlled” | Requirement, factual observation, verifiable evidence: document, record, place, date |
Apply the audit principles | Confusing independence with confidentiality | Link each principle to a concrete example |
Plan an audit | Forgetting the auditee’s constraints: shift teams, remote sites | Start from the risks and the objectives of the audit |
Handle the closing meeting | Negotiating a finding under pressure | Present the facts, record the disagreement, stay with the evidence |
On exam day, read all the questions before answering, allocate your time according to the marks announced, and cite the clause of the standard when an answer calls for it. A short, accurate answer is better than a long, approximate one.
What should you do after the course to become a certified auditor?
Audit, record and apply. The course certificate proves training; listing on the IRCA register, at a grade, also requires audit experience under IRCA rules.
- Keep an audit log from the first audit: date, organisation audited, standard, role (team member or team leader), duration, scope, and the name of the team leader for verification.
- Audit in pairs with an experienced Lead Auditor, then lead increasingly complex audits.
- Ask for written feedback after each audit you lead: it feeds your progress and, where relevant, your application file.
- Submit your application without delay. Check on the CQI website how long your course certificate remains valid for an application, the criteria for each grade and the conditions for maintaining it.
Supplier audits are natural ground for this practice. Our case study of a QHSE manager who became a second-party Lead Auditor shows how to organise the transition.
What mistakes should you avoid?
Those that waste the benefit of the course before the exam, or just after it:
- Enrolling in the course to discover the standard.
- Revising on an outdated edition of the standard, or of ISO 19011.
- Following the course between two meetings, phone in hand.
- Confusing a course certificate with auditor certification on your CV.
- Letting six months go by without auditing after the course.
- Choosing a course without checking its status with the CQI.
Checklist, from the month before to the first audit
In Morocco, an employer that wants to submit the course under the special training contracts (contrats spéciaux de formation, CSF) of OFPPT, the Office de la formation professionnelle et de la promotion du travail (Morocco’s vocational training office), includes it in its training plan before the session.
The factors that drive the price of the course, and CSF funding, are detailed in our article on Lead Auditor course cost.
