What is the main purpose of the IIA standards?

The main purpose of the IIA (Institute of Internal Auditors) standards is to delineate principles representing the practice of internal auditing. These standards serve as authoritative guidelines and provide a framework that outlines how internal auditors should effectively conduct their work. They cover various aspects of internal auditing, including ethical behavior, governance, risk management, and effective communication.

By establishing widely accepted norms and practices, these standards help ensure that internal audits are performed consistently and impartially, ultimately enhancing the credibility and value of internal audit functions within organizations. This contributes to improved risk management, control processes, and governance practices, which are integral to the overall health of an organization.

The other options do not capture the broad and inclusive nature of the IIA standards, which are not limited to financial audits, regulatory compliance, or performance appraisals alone. Instead, they underscore a holistic approach to internal auditing that encompasses various dimensions critical for effective governance and organizational success.
