Most people who ask how to become a lead auditor are asking which course to buy. The course is one step of five, and not the hardest one. What certification bodies and personnel certification bodies actually weigh is what you know about quality systems, what audits you have done, and whether someone who watched you audit would trust you to lead. This guide takes the route in order, with the numbers that are published.
What does an ISO 9001 lead auditor do?
A lead auditor is responsible for a whole audit. He or she plans it, assigns the work by competence, runs the opening and closing meetings, keeps the team on the evidence, decides the findings and their grade with the team, writes the report and, in a certification audit, recommends whether the certificate should be granted. ISO 19011:2026 calls this person the audit team leader.
There are three settings for the work. A first party audit is an internal audit of your own organisation. A second party audit is a customer auditing a supplier. A third party audit is a certification body auditing a client against ISO 9001 under ISO/IEC 17021-1. The skills carry across all three, but only an accredited certification audit puts your work under the eye of an accreditation body such as SANAS. The route for food safety auditors is set out in how to become an ISO 22000 lead auditor, and for OH&S auditors in how to become an ISO 45001 lead auditor in South Africa.
Do you need a degree to become a lead auditor?
No standard requires a degree to become a lead auditor. ISO 19011:2026 clause 7.2.4 says auditor competence is built from education, work experience, auditor training and audit experience, and leaves the weighting to whoever manages the audit programme. IRCA’s published Lead Auditor criteria are about the certified course and the audits, not a degree. Certification bodies set their own entry criteria, and many ask for a qualification and several years of work in a quality or technical role. Read the criteria of the body you want to work with.
Step 1. Know ISO 9001:2026 from the inside
Auditors who have run a quality system find the evidence faster and are harder to bluff. If you have not built or maintained one, learn by doing it, either at work or on a case site. The ISO 9001:2026 Understanding and Implementation course takes about 24 hours and has you build the system clause by clause with working tools. The 2026 edition, published on 16 September 2026, is the one to learn, and our guide to every change from 2015 shows what moved.
Step 2. Start auditing where you are
Internal audits and supplier audits are where most lead auditors learn to sample, interview and write a finding. Ask to join your organisation’s audit programme, then to lead an internal audit of one process. The ISO 9001:2026 Internal Auditor course, about 14 hours, trains you for clause 9.2 and ISO 19011:2026.
Start an audit log on your first audit, not when you apply. For every audit record the date, the organisation (coded if it is confidential), the standard, the type of audit, the IAF code if it is a certification audit, your role, the days on site and remote, and the name of the team leader who can confirm it. Keep a record of your continuing professional development beside it.
Step 3. Pass a lead auditor course
A lead auditor course adds the parts an internal auditor course leaves out, which are third-party certification under ISO/IEC 17021-1, QMS auditor competence under ISO/IEC 17021-3, audit time under Global ACI-TECH-3-004 (formerly IAF MD 5), Stage 1 and Stage 2, leading a team and grading findings major or minor. Our guide to what a 2026 ISO 9001 lead auditor course must cover gives the checklist.
Choose the course to match the body you plan to apply to. IRCA certification asks for an IRCA certified auditor or lead auditor course, and counts only audits done after you pass it. Exemplar Global’s published criteria for its lead auditor certificates ask for a certificate from a course it certifies or from one of its Recognised Training Providers, and its Work Style Assessment. ASC’s ISO 9001:2026 Lead Auditor course is Exemplar Global recognised and is not CQI and IRCA certified, so it fits the Exemplar Global route. If your goal is an IRCA grade, you will need an IRCA certified course for that scheme.
Step 3, done from your desk
ASC’s ISO 9001:2026 Lead Auditor course takes about 45 hours, with a 13-step virtual certification audit and two video proctored exams, and is recognised by Exemplar Global.

Step 4. Log audits that count
This is the step that takes time, and the one that makes you useful to a certification body. IRCA, and the certification bodies that qualify auditors, want proof that you have audited complete management systems and led some of those audits. Exemplar Global no longer asks new applicants for an audit log, but a certification body will still look for audit experience before it lets you lead its audits. IRCA publishes its Lead Auditor experience criteria, which show what an experience-based grade asks for, and it counts only audits done after your training.
| IRCA Lead Auditor criterion | What is asked for |
|---|---|
| Training | A pass in an IRCA certified auditor or lead auditor course covering the standard of the scheme, or an IRCA conversion course |
| Total audit experience | 7 audits and 35 audit days, with at least 25 days on site |
| Full audits | At least 4 management system audits covering every element of the audit cycle, at least 20 days, at least 15 on site |
| Audits led | At least 3 full audits as team leader, at least 15 days, at least 10 on site, each with a team of at least you and one other person |
| Remote audits | Accepted. IRCA asks you to record remote audit time as on site time |
| Time window | Audits done after the course and within 5 years of the date of application |
From the CQI and IRCA Lead Auditor grade requirements, read on 6 November 2026. Some schemes add work experience requirements.
The audits you lead do not all have to be certification audits, but they must be full audits of a management system, not a walk through one department. Internal and supplier audits can build the count, if the body you apply to accepts them. Ask before you rely on them.
Step 5. Qualify or certify as an auditor
There are two kinds of recognition, and many lead auditors hold both.
Qualification by a certification body. A certification body qualifies its auditors against its own criteria under ISO/IEC 17021-1 clause 7 and ISO/IEC 17021-3, by function and by technical area, using IAF codes listed in Global ACI-TECH-3-021 (formerly IAF ID 1). An auditor qualified for code 17, basic metals and fabricated metal products, is not thereby qualified for code 33, information technology. You audit first as an auditor in training beside an appointed evaluator, are observed on witnessed audits, and are monitored after you qualify.
Personnel certification. A personnel certification body certifies you as an individual, against its own published scheme. The two you will meet most often in QMS auditing are these.
| CQI and IRCA | Exemplar Global | |
|---|---|---|
| Grades | From Associate Auditor, which recognises the training before you have the experience, through Auditor and Lead Auditor to Principal Auditor | Auditor, Lead Auditor and Master Auditor. There is no longer a provisional grade |
| Training | An IRCA certified course for the scheme | A certificate from an Exemplar Global certified course or a Recognised Training Provider course for the scheme and grade |
| Experience | Published numbers of audits and days, led audits within 5 years | No audit log for a new application, unless your training certificate is out of date and no knowledge exam is available |
| Other conditions | Application with an audit log, a one-off fee and an annual membership fee per scheme | A Work Style Assessment at first application, repeated every three years |
Grade names and criteria change. Before you apply, download the body’s current requirements document and plan your evidence against it, not against a summary such as this one.
What does ISO 9001:2026 mean for lead auditors who are already certified?
You need transition training. The CQI and IRCA expect IRCA QMS certificated auditors to have until September 2029 to complete transition training to ISO 9001:2026. Under the Global ACI transition rules, certification bodies must have auditors who are competent in the 2026 edition before they audit to it. Certified organisations have until 30 September 2029 to move their certificates.
If you already hold an ISO 9001:2015 lead auditor certificate and only need the changes, Transition to ISO 9001:2026 covers them in about 8 hours for R1 950. If you were trained years ago and want the full method again on the current documents, the lead auditor course is the better buy.
How long does it take to become an ISO 9001 lead auditor?
The courses add up to weeks. The audits set the pace, and that depends on how often you audit complete systems. Thirty five audit days is a lot of internal audits at one site, which is why many lead auditors build the log through supplier audits, consultancy work, or as an auditor in training at a certification body. Someone starting with no quality experience needs time in a quality role first. IRCA’s five year window shows how far back a body will look.
Questions people ask
Can I become an ISO 9001 lead auditor without audit experience?
You can pass a lead auditor course without audit experience. Whether you can be certified without it depends on the body. IRCA’s Lead Auditor grade asks for 7 audits and 35 audit days after the course, at least 3 led as team leader, and its Associate Auditor grade recognises training before experience. Exemplar Global asks new applicants for a recognised course certificate and a Work Style Assessment, not an audit log. A certification body will still want audit experience before it lets you lead its audits.
How long does it take to become an ISO 9001 lead auditor?
The training takes weeks, about 45 hours for ASC’s online lead auditor course. Building the audit log takes longer and depends on how often you audit complete systems. IRCA counts audits done after the course and within five years of the application.
Do I need a degree to become a lead auditor?
No standard requires one. ISO 19011:2026 builds auditor competence from education, work experience, training and audit experience. Certification bodies set their own entry criteria, and some ask for a qualification, so check the body you want to audit for.
Is an online lead auditor course accepted?
It depends on the body you apply to. Exemplar Global’s recognition of ASC covers its courses online, in a live virtual class and in class. IRCA asks for an IRCA certified course, and ASC’s course is not IRCA certified. Check the current requirements of your chosen body before you enrol.
What is the difference between an internal auditor and a lead auditor?
An internal auditor audits his or her own organisation under clause 9.2. A lead auditor leads audits of other organisations, such as supplier or certification audits, and adds third-party certification rules, audit time, team leadership and grading findings major or minor.
Do ISO 9001:2015 lead auditors need retraining for ISO 9001:2026?
Yes, transition training. The CQI and IRCA expect IRCA QMS certificated auditors to have until September 2029 to complete it, and certification bodies must have auditors competent in the 2026 edition before they audit to it.
What should an audit log contain?
For every audit, the date, the organisation, the standard, the audit type, the IAF code for certification audits, your role, the days on site and remote, and a team leader who can confirm it. Keep a CPD record beside it.
