The International Register of Certificated Auditors (IRCA) is without a doubt the most prestigious institution for examining executive frameworks and ISO 9001 courses all over the world. This implies that once you’ve completed the ISO 9001 lead auditor course, almost any company in the globe will acknowledge your achievement. Passing the ISO 9001 lead auditor course also qualifies you for CQI Practitioner (PCQI) membership, as IRCA is a subsidiary of the Chartered Quality Institute (CQI).
