Integrated Management Systems Internal Auditor Training Course (Self-Paced Online)

This comprehensive self paced online course prepares you to plan and conduct internal audits of an integrated management system against ISO 9001:2026, ISO 45001:2018 and ISO 14001:2026 together. You will learn to carry an internal audit from initiation through to reporting and follow up, using ISO 19011:2026 as your auditing framework.

The course follows a realistic, scenario based approach, so you practise the internal audit lifecycle the way it happens in the field: planning the audit, gathering and evaluating evidence, raising findings, and reporting to management. It opens with a concise recap of all three standards so you are grounded in quality, health and safety, and environmental requirements before you audit against them, and shows how the shared Harmonised Structure lets you audit common clauses once while still testing each discipline properly.

Key concepts covered

• The three standards in brief, and how they combine into one integrated management system
• The seven principles of auditing and the audit lifecycle
• Audit initiation, scope, criteria and the audit plan across three disciplines
• Auditing shared clauses once: context, leadership, planning, support, performance evaluation and improvement
• Auditing the discipline specific engines: the process approach and customer focus, hazard identification, the hierarchy of controls and worker consultation, and environmental aspects, impacts, life cycle and compliance obligations
• Evidence gathering, and distinguishing evidence from inference
• Writing Major NC, Minor NC, and OFI statements, and verifying corrective action

Becoming an internal auditor across ISO 9001:2026, ISO 45001:2018, ISO 14001:2026 and ISO 19011:2026 strengthens your value to any organisation running an integrated management system. This course enables you to:

• Plan and conduct integrated internal audits with confidence and consistency
• Audit three standards in a single, efficient pass rather than three separate exercises
• Surface the issues that matter across quality, safety and the environment
• Help your organisation stay audit ready for certification and surveillance
• Take a clear next step in your auditing career, including towards the Lead Auditor qualification

A working knowledge of the current versions of ISO 9001, ISO 45001 and ISO 14001 is recommended and will help you get the most from the auditing material. If you are new to any of the standards, you can build this foundation through our Foundation courses in ISO 9001, ISO 45001 and ISO 14001. This course also includes a concise recap of all three standards before the auditing modules.
