AUD Risk Response · Updated November 2026
Nature, Timing, Extent: How Does the Auditor Respond to Higher Risk?
Higher assessed risk changes what evidence the auditor obtains, when it is obtained, and how much is obtained.
Nature
The auditor can choose more persuasive procedures, such as external confirmation or reperformance, when risk is higher.
Timing
Higher-risk areas may push testing closer to year-end instead of relying heavily on interim work.
Extent
Higher risk often means larger sample sizes or more items tested, all else equal.
Combined response
Risk responses usually change more than one dimension at once, so do not treat nature, timing, and extent as isolated memorization terms.
The takeaway
Nature means what procedure. Timing means when. Extent means how much.
