There is no single licence that makes you an ISO 22000 lead auditor. There is a route, and every organisation that uses lead auditors checks a slightly different set of things along it. The people who get there fastest work out early which organisation they want to audit for and build the evidence that organisation asks for.
Below is the route as it stands in 2026, with real requirements from the FSSC 22000 version 7 scheme as a worked example, and an honest view of where training fits.
What does an FSMS lead auditor do that an auditor does not?
An auditor collects and judges evidence. A lead auditor is accountable for the whole audit. They agree the scope and plan the time. They pick and brief the team and chair the opening and closing meetings. When auditors disagree about a grade, the lead auditor settles it, then signs the report and makes the recommendation to the certification body.
The job changes with the type of audit. A first-party audit is an organisation auditing itself, the internal audit. A second-party audit is one organisation auditing another, usually a customer auditing a supplier. A third-party audit is carried out by an independent body, such as a certification body checking conformity with a standard. Most lead auditor careers start in the first two and move into the third.
What are the requirements to become a food safety lead auditor?
Each certification body sets its own competence criteria under ISO/IEC 17021-1 and ISO 22003-1, and schemes add their own. FSSC 22000 version 7, published in May 2026, is a useful benchmark because it spells its rules out. These are its initial requirements for a certification body’s FSSC 22000 auditors (Part 4, section 3.5.1).
| Requirement | What FSSC 22000 version 7 asks of certification body auditors |
|---|---|
| Work experience | At least 2 years’ full-time work in the food or an associated industry, taking an active role in food safety functions. Consultancy can count for at most six months of that. |
| Education | A degree in a food related or bioscience discipline, or a food related or bioscience higher education course, or equivalent. |
| Lead auditor training | A lead auditor course for FSMS or QMS of at least 40 hours with an exam, including ISO 19011 and the relevant parts of ISO/IEC 17021-1. The scheme also asks for the course to have external recognition from a competent body. |
| Other training | HACCP (16 hours), ISO 22000 (8 hours if not in the lead auditor course), food defence (2 hours), food fraud (2 hours), the scheme requirements and ISO 22002-100 with the relevant parts (3 hours). |
| Audit experience | At least ten audit days, including at least five third-party food safety certification audits covering FSMS, HACCP and PRP requirements in the sector. |
| Sign-off | Supervised training, then a witnessed audit, then pre-approval of the auditor profile by the Foundation. |
Read the last training row carefully. A certification body auditing a GFSI benchmarked scheme may need your lead auditor course to carry a specific kind of external recognition. Our course certificate is evidence of training. It is not a personnel certification, and we do not claim any outside recognition for it. If certification body work under a particular scheme is your target, check that scheme’s current rules and ask the certification body before you buy any course, ours included.
The bar is different for internal auditing. Under the same scheme, a multi-site organisation’s internal audit team must be led by someone who has completed an FSMS, QMS or FSSC 22000 lead auditor course of 40 hours (Part 2, clause 2.5.18.2), with at least 2 years in the food industry and at least 1 year in the organisation.
Build the lead auditor skills first
About 44.5 hours online: ISO 22000 through an auditor’s eyes, ISO 19011:2026, third-party certification and a full virtual audit marked by an examiner. Learn it once, properly, at your own pace.
The route, step by step
- Work in food safety. QA, production or a technical role all count, and so does inspection work. Two years is the common floor, and the time you spend making an FSMS work is what lets you judge one later.
- Know HACCP and ISO 22000 well. You should be able to tell a PRP, an OPRP and a CCP apart from the evidence, and know where the hazard control plan sits (clause 8.5.4).
- Audit your own site. Join the internal audit team. It is the cheapest audit experience you will ever get.
- Take lead auditor training with an exam. This is where you learn planning, team leadership, grading and reporting to the standard a certification body uses.
- Audit as a team member, and log every day. Date, site, sector, standard, your role and the days on site. Logs written up years later are not believed.
- Lead audits under supervision. A certification body will usually want to see you lead before it lets you lead alone.
- Apply. To a certification body for qualification in the categories you know, and if you want it, to a personnel certification body for registration. Each decides on its own criteria.
- Keep your competence current. ISO 19011 covers the evaluation of auditor competence, and certification bodies monitor their auditors’ performance. New editions keep coming. In the last two years alone, ISO 22000 was amended, the ISO 22002 PRP series was rewritten and ISO 19011 was republished.
Which skills separate a lead auditor from an auditor?
The ones nobody can bluff. A certification body watching you on a witnessed audit is not checking whether you can quote clause 9.2. It is checking whether you can run the day.
In our course these skills each get their own lessons and practice:
- planning Stage 2 and allocating auditor time by process and risk
- running an opening meeting minute by minute, and a closing meeting where a senior manager disputes a major
- interviewing every level, from a cleaner on night shift to the managing director, and reading the room
- handling obstacles, resistance and deception without losing the evidence trail
- judging whether evidence is relevant, sufficient and reliable
- writing findings that survive challenge and grading them major or minor, with the scheme critical grade explained
- reviewing a corrective action plan and deciding whether the root cause is real
Then you do all of it on one company. The capstone is a 13-step virtual certification audit of Abita Dairy, about 13 hours of work, marked out of 100 by a named examiner, with 70 to pass.
How long does it take to become a lead auditor?
The training is the quick part. Our course is about 44.5 hours, and at four hours a week most people finish in roughly eleven weeks, inside the 12 months of access. The audit days take longer, because you depend on audits being available to join. Start logging from your first internal audit and the total builds faster than you expect.
Where do ISO 22000 lead auditors work?
| Where | Type of audit | What they usually look for |
|---|---|---|
| Certification bodies | Third party | Category experience, scheme qualification, witnessed audits, calibration |
| Retailers and brand owners | Second party, supplier and co-packer audits | Sector knowledge, legal compliance in the markets they sell to, firm but fair findings |
| Multi-site manufacturers | First party, central internal audit | Lead auditor training, independence from the sites audited, consistent grading |
| Consultancies | Gap assessments and mock audits | Breadth across schemes, report writing, a clear separation between auditing and advising |
For second-party and internal roles, the employer decides what competence it needs, and a tested lead auditor certificate on the current editions carries real weight. For a closer look at the difference between an inspection and an audit, see our post on food safety inspection versus audit.
Where should you start if you are not ready yet?
Our course assumes you already know HACCP and ISO 22000, and a short entry check at the start tells you if you are ready. If you score below 60 percent, take Implementation of ISO 22000:2018 first. If you know the standard but have never audited, Internal and Supplier Auditing Practices gets you onto your site’s internal audit team, which is step three of the route.

Frequently asked questions
How do you become an ISO 22000 lead auditor?
Build food industry experience, learn HACCP and ISO 22000 well, join internal audits, complete lead auditor training with an exam, then log audits as a team member and as a supervised lead. Certification bodies and personnel certification bodies each apply their own criteria to that evidence.
What are the requirements for an FSMS lead auditor?
They vary by organisation. As an example, FSSC 22000 version 7 asks certification body auditors for 2 years of food industry experience, a food or bioscience degree or equivalent, a 40-hour lead auditor course with an exam, HACCP and other training, and at least ten audit days including five third-party certification audits.
Do I need a degree to become a food safety lead auditor?
For certification body work under FSSC 22000 version 7, a food related or bioscience degree or higher education course, or equivalent, is required. Second-party and internal roles are set by the employer and are often more flexible.
How many audits do I need before I can lead one?
FSSC 22000 version 7 asks certification body auditors for at least ten audit days, including at least five third-party food safety certification audits, before qualification. Other organisations set their own numbers, so keep a dated log from your first audit.
Does a lead auditor course make me a certified lead auditor?
No. A course certificate is evidence of training. Registration as an auditor is a separate step with a personnel certification body, which decides on its own criteria, and certification bodies evaluate auditors again before using them.
How long is the ASC ISO 22000 lead auditor course?
About 44.5 hours, including the 13-hour virtual audit and the two proctored exams. It is self-paced with no live sessions and 12 months of access, so at four hours a week most people finish in roughly eleven weeks.
Can I become a lead auditor without auditing experience?
You can complete the training, but you cannot skip the audit days. Join your own site’s internal audit team as early as possible and log every audit with the date, site, standard and your role.
