The chief audit executive (CAE) has assigned an internal auditor to an upcoming engagement.

Introduction:

Assurance engagements require internal auditors to maintain objectivity and avoid conflicts of interest.

Role of Internal Auditors in Assurance Engagements:

They must remain independent and not take on roles that could compromise their impartiality.

Options Analysis:

Option A: Determining the objectives, scope, and techniques can be part of their role but does not define an assurance engagement specifically.

Option B: The CAE obtaining skills or competencies personally is not a standard requirement for assurance engagements.

Option C: Not assuming management responsibilities is crucial to maintain independence and objectivity during assurance engagements.

Option D: While maintaining objectivity is important, it is not the distinguishing feature of being assigned to an assurance engagement.

Conclusion:

The key requirement indicating an internal auditor was assigned to an assurance engagement is that they must not assume management responsibilities during the engagement.
