What are the prerequisites and experience requirements for ISO 27001 Lead Auditor?
One prerequisite to attend, and a separate experience record for the credential.
Every great mission starts with reconn.
PECB lists a fundamental understanding of ISO/IEC 27001 and comprehensive knowledge of audit principles as the prerequisite for the Lead Auditor course. Experience affects the credential, not the exam. Lead Auditor needs five years of experience, two in information security management, plus 300 audit hours. With none, you earn Provisional Auditor.
Treat attending and holding the credential as two separate steps.
To attend the course
You need a fundamental understanding of ISO/IEC 27001 and good knowledge of audit principles. If ISO 27001 is new to you, start with Foundation or Lead Implementer.
To hold the credential
Every level needs the Lead Auditor exam or an equivalent and signing the PECB Code of Ethics. Experience decides the level.
| Credential level | Work experience | Project or audit hours |
|---|---|---|
| Provisional (Implementer or Auditor) | None | None |
| Implementer or Auditor | 2 years, 1 in information security management | 200 hours |
| Lead Implementer or Lead Auditor | 5 years, 2 in information security management | 300 hours |
| Senior Lead Implementer or Senior Lead Auditor | 10 years, 7 in information security management | 1,000 hours |
From my side of the table. Audit hours count when they are documented. Record the audit, your role, the dates and the hours as you go.
