The ISO/IEC 20000 Auditor exam format, explained

The same shape as Foundation — forty questions, an hour, closed book, twenty-six to pass — asked from the other side of the table. And it is the one level APMG does not offer for self-study.

Same numbers, different question

On paper the Auditor exam looks like Foundation. The difference is the angle. Foundation asks what the standard requires; Auditor asks whether what you are shown meets it, what evidence would prove it, and what you would write down if it does not.

Expect questions about audit principles and terms, the types of audit (first, second and third party), planning and conducting an audit, sampling and evidence, and how nonconformities are classified, reported and followed up.

Why there is no self-study route

For Foundation and Practitioner, APMG lets you buy the standard, buy an exam and sit it. For Auditor it does not: the qualification is reached through an accredited course. Plan the budget accordingly — the exam is not something to book on its own.

Check the edition

ISO/IEC 20000-1:2018 is the edition organizations are certified against today. APMG’s Auditor description still refers to the 2011 edition, so ask your trainer which edition the course and the exam are aligned with before you start. The audit skills do not change; the clause numbers do.

What this means for how you prepare

Know the requirements well enough to recognise them in someone else’s evidence. Practise turning a situation into a finding: what was required, what was observed, why it is or is not a nonconformity. Sixty minutes for forty questions leaves no time to look anything up.

Questions people ask

How many questions are in the ISO/IEC 20000 Auditor exam?

Forty multiple-choice questions.

What is the pass mark?

Twenty-six out of forty — 65%.

How long is the exam?

Sixty minutes, closed book.

Can I prepare on my own?

No. APMG does not offer the Auditor level as self-study: you take it through an accredited course.

Do I need the Foundation certificate first?

It is not a formal prerequisite, but a working knowledge of ISO/IEC 20000-1 is assumed, and auditing experience is recommended.

Does this make me a lead auditor for a certification body?

Not on its own. Certification bodies set their own competence requirements for their auditors.
