Engagement quality review

An engagement quality review is an objective evaluation, performed by a qualified person who is not on the engagement team, of significant judgments made and conclusions reached before the report is released.

CORAA TeamUpdated November 5, 2026

Definition

Under SQMS 1, a firm sets criteria for engagements that need an engagement quality review, often called EQR. SQMS 2 sets who may perform it: a reviewer outside the engagement team, with the competence and authority for the role, who meets objectivity and cooling-off requirements. The review covers significant judgments and the conclusions on the report, before it is dated.

Why it matters in an audit or review

An EQR adds a second look at the highest risk matters, such as going concern, fraud risk responses and complex estimates. Peer reviewers check whether required reviews were performed, documented and timely, so gaps are a recurring finding.

Example

Illustrative: a firm requires an EQR for all audits of entities with debt covenants. The reviewer spends 6 hours on a $25,000,000 client, focusing on revenue risk and the going concern evaluation, and signs off on March 10 before the March 14 report date.

Common mistakes

  • Completing the review after the report is released.
  • Using a reviewer who worked on the engagement.
  • Documenting the sign-off but not what the reviewer examined.

FAQ

When must an engagement quality review be complete?
