What is the group engagement partner?
Inspection findings from the FRC and PCAOB consistently flag the same problem on group audits: insufficient partner involvement. In a typical finding, the partner signed the group opinion without reviewing component auditor (CA) conclusions or the group-level risk assessment. ISA 600 (Revised) was written specifically to close that gap.
Under ISA 600 (Revised), the group engagement partner (GEP) directs and supervises the group audit engagement. This mirrors the EP role under ISA 220 (Revised), but ISA 600 adds specific group audit requirements. Involvement cannot be a tick box exercise. A GEP must be sufficiently involved in CA work to take personal responsibility for the group audit opinion.
ISA 600 (Revised).13 requires the GEP to determine that the group engagement team has the competence and capabilities to perform the group audit. That involvement extends to reviewing risk assessments across components and evaluating whether audit evidence from CAs is sufficient. Where it is not, the GEP determines what additional procedures are needed at group level.
Responsibility for the overall group audit strategy sits with the GEP under ISA 600 (Revised).17. No GEP can sign the group auditor's report without being satisfied that sufficient appropriate audit evidence has been obtained from work performed across all components.
Key Points
- Ultimate responsibility for the group audit opinion rests with the GEP, not the team.
- ISA 600 (Revised) expanded the GEP's required involvement in risk assessment and CA oversight.
- Delegating work to the group engagement team does not transfer responsibility from the GEP.
- Inspection findings frequently cite insufficient GEP involvement in group scoping and risk assessment.
Worked example: Leitner Bau AG
Client: Austrian construction group, FY2024, consolidated revenue €180M, IFRS reporter, four subsidiaries, with the two largest in Austria and one each in Germany and Croatia.
Determine team competence
Before fieldwork begins, the GEP confirms that the group engagement team includes a senior with group audit experience and that the Croatian CA holds the required local qualification. Independence of the German CA is also confirmed at this stage.
Direct the risk assessment
The GEP reviews the team's identification of risks of material misstatement across all four components. The Croatian subsidiary's construction contract accounting (percentage-of-completion under IFRS 15 ) presents a significant risk that the team's initial assessment had classified as moderate, so the GEP upgrades the risk classification. This is exactly the kind of judgment that cannot be delegated to the manager and rubber-stamped later.
Evaluate component auditor work
At completion, the GEP reviews the Croatian CA's report on revenue and the German CA's work on a €9M intercompany loan. Additional procedures are requested from the Croatian CA on cost-to-complete assumptions. Only after that additional evidence is received and evaluated does the GEP sign the group auditor's report.
What reviewers and practitioners get wrong
FRC annual inspection reports have repeatedly identified insufficient GEP involvement as a recurring finding. In our experience, the pattern is consistent: the GEP delegates the CA relationship entirely to the manager and does not review risk assessments or CA conclusions before signing. Nobody enjoys pushing back on a partner's sign-off timeline, but we think this is the single most common root cause of group audit review notes.
Some GEPs treat the role as administrative (signing the opinion and the engagement letter) rather than substantive. ISA 600 (Revised).13 requires involvement in direction and supervision of the group audit, not just the sign-off. When the file should tell a story of active partner involvement but instead shows only a signature on the final page, that gap is the inspection finding waiting to happen.

Frequently asked questions
Can the group engagement partner delegate responsibility for the group opinion?
No. Delegation to the group engagement team does not transfer responsibility from the GEP. ISA 600 (Revised) requires the GEP to be sufficiently involved in CA work to take responsibility for the group audit opinion. Without satisfaction that sufficient appropriate audit evidence has been obtained, the GEP cannot sign the group auditor's report.
What do inspectors look for regarding partner involvement?
Inspection findings frequently cite insufficient GEP involvement in group scoping and risk assessment. In a common pattern, the GEP delegates the CA relationship entirely to the manager and does not review risk assessments or CA conclusions before signing.
