When should audit quality concerns be escalated beyond the engagement team?

Escalation may be appropriate when the issue is not an isolated review disagreement but a pattern that threatens audit quality. Examples include repeated factual errors, unsupported rating changes, final reports that conflict with workpaper evidence, or recommendations that show the audit team does not understand the process.

The first route is usually within internal audit: engagement manager, CAE, methodology owner, or quality review process. If the CAE is the source of the quality problem and the issue affects the credibility of internal audit, the organization's governance reporting line may become relevant.

The CIA answer should be measured. Do not bypass governance impulsively, but do not allow unsupported conclusions to stand without appropriate escalation.
