What's the difference between the ISO 9001, ISO 14001, ISO 45001 and ISO 27001 Lead Auditor courses?
All four are 40-hour Lead Auditor courses delivered as CQI and IRCA Certified Training, with the same training format, but each covers a different management system: ISO 9001 focuses on Quality Management (QMS), ISO 14001 on Environmental Management (EMS), ISO 45001 on Occupational Health & Safety Management (OHSMS), and ISO/IEC 27001 on Information Security Management (ISMS).
Which ISO Lead Auditor course should I start with?
Most learners start with the course closest to their current role — quality professionals typically begin with ISO 9001, environmental and sustainability professionals with ISO 14001, HSE professionals with ISO 45001, and IT/information security professionals with ISO/IEC 27001. There is no required order to take them in.
Can I take more than one Lead Auditor course?
