How to Build Audit Experience Before Lead Auditor Training

Why Experience Matters More Than You Think

Lead auditor training is often treated as the starting line. People enrol, complete the course, pass the exam, and then wonder why they are struggling to find work or why the course felt abstract and disconnected from reality. The truth is that lead auditor training works best when you already have some audit experience to hang the theory on. Without it, the concepts stay theoretical and the skills do not stick.

Building audit experience before lead auditor training is not just helpful. For most certification schemes, it is a formal requirement. Exemplar Global and IRCA both require documented audit days before you can achieve full auditor registration. But beyond the paperwork, experience genuinely changes how much you get out of the course. You ask better questions, you connect the methodology to real situations you have encountered, and you leave with practical skills rather than a certificate you cannot use.

This article is for people who are serious about becoming a competent lead auditor, not just a credentialled one. It covers how to build genuine audit experience from wherever you are starting, including inside your current organisation, through volunteer roles, and through deliberate practice that prepares you for the real thing.

Understand What Counts as Audit Experience

Before you start accumulating experience, you need to know what actually counts. Most certification schemes measure audit experience in days. Exemplar Global, for example, requires a certain number of audit days completed within a defined period before you can apply for full certification. These days need to be documented in an audit log.

An audit day generally means a full working day spent conducting audit activities. That includes planning, interviewing, reviewing evidence, writing findings, and participating in opening and closing meetings. Observation days, where you shadow an experienced auditor without leading any part of the audit, typically count at a reduced rate or are treated separately. Check the specific requirements of the scheme you are targeting before you start logging.

What does not count is general compliance work, document review for implementation purposes, or attending management reviews as a participant. There is a meaningful difference between working in a quality or safety role and actually auditing. Keep that distinction clear in your own mind and in your log.

For a detailed breakdown of how to maintain your log correctly, see our guide on how to keep an audit log for auditor certification.

Start With Internal Audits in Your Current Organisation

The most accessible source of audit experience for most people is their own workplace. If your organisation has an ISO certified management system, there is almost certainly an internal audit programme that needs people to run it. Volunteering to conduct internal audits is the single most practical step you can take right now.

How to Get Involved in Your Internal Audit Programme

Talk to your quality manager, HSE manager, or whoever owns the management system. Explain that you are working toward lead auditor training and that you want to build documented audit experience. Most organisations are genuinely grateful for people who want to take on internal audit responsibilities. It reduces the burden on whoever is currently doing it.

Start by shadowing an experienced internal auditor on a couple of audits. Watch how they structure their time, how they phrase questions, how they handle a defensive auditee, and how they record evidence. Then ask to lead a section of an audit yourself, with the experienced auditor present as an observer. This is the fastest way to develop real skill.

Once you have a few audits under your belt, start leading full internal audits independently. Document every one. Record the date, the scope, the standard audited against, the duration, and your role. That log is your evidence for certification purposes and for future employers.

What to Focus on as a New Internal Auditor

Do not try to audit everything perfectly from the start. Focus on three fundamentals. First, learn to ask open questions that get people talking rather than closed questions that produce yes or no answers. Second, learn to follow the evidence rather than the checklist. When something does not add up, dig deeper. Third, learn to write findings clearly and specifically, with a statement of what was observed, what requirement it relates to, and where the objective evidence was found.

These three skills separate competent auditors from people who just tick boxes. The sooner you develop them, the better your lead auditor training experience will be.

Volunteer for Cross Functional Audit Teams

Many larger organisations run internal audit programmes using cross functional audit teams. This means people from different departments audit areas outside their own. If your organisation does this, put your hand up. If it does not, suggest it to whoever manages the audit programme.

Cross functional auditing is valuable for two reasons. It removes the conflict of interest that comes with auditing your own area, and it exposes you to parts of the business you would not normally see. Auditing procurement when you work in operations, or auditing IT controls when you work in quality, builds a broader understanding of how management systems function across an organisation. That breadth is exactly what lead auditors need.

It also builds the interpersonal skills that are harder to teach. Walking into a department where you are not known, building rapport quickly, asking probing questions of people who did not choose to be audited, and maintaining objectivity when the auditee pushes back. These are the real skills of auditing, and you only develop them by doing.

Pursue Supplier Audit Opportunities

Second party audits, where your organisation audits its suppliers, are an excellent source of experience that many people overlook. These audits are more demanding than internal audits because you are auditing an external organisation, the relationship dynamics are different, and the stakes are higher. They are also far more relevant to lead auditor work.

Talk to your procurement or supply chain team about whether your organisation conducts supplier audits. If it does, ask to be included as an audit team member. If it does not, you could propose a supplier audit programme as a value adding project. Many organisations do informal supplier visits without treating them as formal audits. Formalising that process, even partially, gives you documented audit experience and delivers real value to the business.

When you do get the opportunity to participate in a supplier audit, pay attention to how the pre audit preparation works. How do you define the scope? What documents do you request in advance? How do you structure the day when you have limited time and an unfamiliar environment? These questions matter in lead auditor work and you will only find the answers through practice.

Complete an Internal Auditor Course First

If you have not already completed an internal auditor course, do that before you enrol in lead auditor training. This is not just about meeting prerequisites. It is about getting far more value from the lead auditor course when you eventually do it.

An internal auditor course teaches you the fundamentals of audit methodology. How to plan an audit, how to gather evidence, how to write findings, and how to understand the requirements of the relevant standard. With that foundation in place, the lead auditor course can focus on the additional skills specific to leading an audit team, managing audit programmes, and conducting third party audits. Without the foundation, you spend the lead auditor course catching up on basics instead of developing advanced skills.

Most lead auditor courses list an internal auditor course or equivalent knowledge as a prerequisite. Some providers enforce this strictly. Others are more relaxed about it. Regardless of what a provider requires, you will get significantly more out of the lead auditor course if you come in with internal auditor training and some practical experience already behind you.

For a clear breakdown of what each level covers and how they differ, see our article on ISO lead auditor vs internal auditor: which course do you need.

Shadow an Experienced Auditor on External Audits

One of the most underused ways to build experience is to observe external audits as a witness or shadow. This is sometimes called a witness audit from the auditor perspective, though technically a witness audit is when a certification body observes an auditor. What we are describing here is simply accompanying an experienced auditor during a real external audit to observe and learn.

How do you get this opportunity? A few practical approaches. If your organisation uses a consultant who conducts supplier audits, ask if you can join as an observer. If you know a lead auditor professionally, ask if they would be willing to let you observe an audit. Some certification bodies also allow shadow auditors on certain engagements, particularly for training purposes.

When you do get the chance to observe an external audit, go prepared. Have a copy of the relevant standard. Bring your own notepad. Watch how the lead auditor manages time, how they structure the opening meeting, how they transition between audit areas, and how they handle unexpected findings. Then debrief with them afterward. Ask what they were thinking at key moments. That conversation is often more valuable than the audit itself.

Build Your Standard Knowledge Deliberately

Audit experience without standard knowledge is incomplete. You need to understand the requirements of the standard you are auditing against well enough to identify when something falls short. This is not about memorising clause numbers. It is about understanding the intent behind each requirement and being able to recognise when an organisation is meeting the spirit of the standard versus just producing documentation to satisfy an auditor.

Read the standard you intend to audit against. Then read it again. Work through each clause and ask yourself: what would a well implemented version of this look like? What would a poorly implemented version look like? What evidence would I expect to see? This kind of deliberate study, combined with practical audit experience, builds the judgement that separates good auditors from average ones.

It also helps to read audit findings from real audits. Some certification bodies publish summaries of common nonconformities. Industry associations sometimes share case studies. Reading these helps you understand what actually goes wrong in real management systems and how experienced auditors identify and document those issues.

Develop Your Audit Technique Through Deliberate Practice

Technique matters as much as knowledge. You can know every clause of ISO 9001 and still conduct a poor audit if your interview technique is weak, your note taking is disorganised, or your findings are vague. Deliberate practice means working on specific skills, not just accumulating hours.

Interview Technique

Practice asking open questions in everyday conversations. When you are in a meeting and someone describes a process, ask a follow up question that requires them to explain rather than confirm. Get comfortable with silence. Most people feel the urge to fill silence by talking. As an auditor, silence is a tool. If you ask a question and the auditee pauses, wait. Often the most useful information comes after the pause.

Note Taking

Develop a consistent note taking system before you need it under pressure. Some auditors use a structured template. Others use a simple two column format with observations on one side and clause references on the other. Whatever system you use, practice it until it is automatic. You cannot be fully present in an interview if you are also trying to figure out how to organise your notes.

Finding Writing

After every audit you conduct, spend time reviewing your findings. Are they specific? Do they cite objective evidence? Do they clearly link the observation to a requirement? Ask a more experienced auditor to review your findings and give you honest feedback. This is one of the fastest ways to improve.

Our article on how to write audit findings that stand up to challenge covers the mechanics of finding writing in detail and is worth reading before your next audit.

Build a Professional Network in the Audit Community

Auditing is a relationship business. The people who progress fastest are those who know experienced auditors, certification body staff, and quality professionals across multiple industries. Building that network before you do your lead auditor training means you already have connections who can help you find audit opportunities, give you honest career advice, and potentially refer work to you once you are qualified.

Practical ways to build this network include joining professional associations such as the Australian Organisation for Quality or the Quality Society of Australasia, attending industry events and conferences, and engaging in online communities for quality and safety professionals. LinkedIn is a genuinely useful tool here. Connect with lead auditors, follow certification bodies, and engage with content about auditing. You will learn from what people share and you will become visible to people who might later hire you or refer opportunities to you.

Do not underestimate the value of conversations with people who are a few steps ahead of you on the same path. Someone who completed their lead auditor training two or three years ago and is now working as a contract auditor can give you far more practical guidance than any generic career resource.

Track Everything You Do

From the moment you start building audit experience, keep a detailed record. Every internal audit you conduct, every supplier audit you participate in, every shadow opportunity, every training course. Record the date, the organisation audited, the standard, the scope, the duration, and your role. Keep copies of any audit plans, checklists, or reports that you produced.

This record serves two purposes. It is the evidence you need for certification applications. And it is the foundation of your professional story when you are applying for roles or contracts. Being able to say that you have conducted 15 internal audits across ISO 9001 and ISO 45001, participated in four supplier audits, and shadowed a lead auditor on two certification audits is far more compelling than saying you completed a training course.

The progression from internal auditor to lead auditor is well documented in our article on from internal auditor to lead auditor: the progression path, which includes guidance on what experience levels you need at each stage.

When You Are Ready for Lead Auditor Training

You will know you are ready for lead auditor training when you can conduct a full internal audit independently, write clear and defensible findings, and have a genuine understanding of the standard you want to specialise in. You do not need to be an expert. You need to be experienced enough that the advanced content of the lead auditor course builds on something real rather than landing in a vacuum.

At Audit Workshop, our lead auditor courses are designed for people who come in with that foundation. Our trainer, Dilawar Laghari, has conducted over 500 external ISO certification audits and brings that practical depth into every session. The courses are available in live and self paced formats across ISO 9001, ISO 14001, ISO 45001, ISO 27001, ISO 42001, ISO 37001, and ISO 13485. If you are building toward lead auditor training and want to understand exactly what prerequisites each course requires, our lead auditor course prerequisites explained article is a good place to start.

Build the experience first. The training will do far more for you when you do.
