Do I need ISO 9001 Lead Implementer or Lead Auditor before the Transition course?

No certification is required, but you need working knowledge of ISO 9001:2015, ideally from implementing, maintaining or auditing a certified QMS. The course covers only the differences. Without prior ISO 9001 exposure, take ISO 9001 Lead Implementer or Lead Auditor first.

The ISO 9001 Transition course has no formal entry requirement, and its certification requires no professional experience. What it assumes is familiarity with ISO 9001:2015: the process approach, PDCA, risk-based thinking and the structure of clauses 4 to 10. The two days go on clause comparisons, not on quality management fundamentals.

Participants who have run, maintained or audited a certified QMS follow the comparisons easily and can judge which changes affect their own system. Those with no ISO 9001 exposure tend to struggle, because each exercise asks them to decide what an existing QMS must change.

If you are new to ISO 9001, start with ISO 9001 Lead Implementer if you will own a QMS, or ISO 9001 Lead Auditor if you will audit one. Both are four-day courses. If you already hold one of these credentials, the Transition course adds proof of competence on the 2026 edition without repeating what you know.

Unsure which route fits your role? Transition versus Lead Implementer and Lead Auditor compares the three.
