The right auditor course depends on the work you want to do. Internal auditor training usually focuses on checking your own organisation’s management system. Lead auditor training develops the skills to plan and lead audits.
Start with your goal
- I need to audit my organisation’s work: explore internal auditor courses.
- I want to plan and lead audits: explore full lead auditor courses and their entry requirements.
- I already have auditor training and want to add a subject: check whether you qualify for a conversion course.
- I need to set up or improve a management system: requirements or implementation training may suit your work.
- I need to understand a new edition of a standard: look for transition training.
What does internal auditor training cover?
Internal auditors check whether their organisation’s processes meet the relevant requirements and work as intended. A course typically covers preparing for an audit, gathering evidence, identifying issues and reporting findings.
Look for practical exercises and check whether you need an understanding of the ISO standard before starting.
What does lead auditor training cover?
Lead auditor training usually covers a broader range of audit planning and leadership skills. It may involve working as part of an audit team, managing the audit process and presenting conclusions.
These courses are often more intensive. Check the standard knowledge and experience expected, how you will be assessed, and whether the training has any recognition you need.
If your goal is professional auditor registration or work for a certification body, ask about the full requirements. You may also need work experience, completed audits and a separate assessment of your competence.
How is a conversion course different?
A conversion course builds on auditor training or experience you already have. It helps you move into another subject without repeating all the training from a full course. Each provider sets its own entry requirements, so check that your background meets them.
What if I need to build the system?
If your role involves setting up processes and helping people use them, look at implementation training. If you first need to understand the standard, requirements or foundation training can help you get started.
Some jobs involve both implementation and auditing. Choose your first course around the task you need to tackle next.
How much time should I allow?
Our checked ISO 9001 examples include two-day internal auditor courses and five-day lead auditor courses. ISO 42001 examples include two-day internal auditor, three-day conversion and four-day lead auditor training. These are examples, not fixed rules: include preparation, exam time and any later assessment when planning your diary.
Does passing make me a registered lead auditor?
Passing a training course is one step. The IRCA Lead Auditor grade also requires relevant audit experience, including leading an audit team. Check the requirements for your intended scheme and role before choosing training.
If you want to carry out your first internal audits at work, ask who will supervise you and how you will gain practical experience after the course.
