When communicating the results of the quality assurance and improvement program (QAIP) to the board of a large organization, the chief audit executive (CAE) should explain the rating conclusions and the impact of the results from the external assessment. This ensures transparency and helps the board understand the effectiveness and areas for improvement in the internal audit function.

Rating Conclusions: These provide a summary of the overall quality and performance of the internal audit function.

Impact Explanation: Discussing the impact helps the board understand how the results affect the internal audit's ability to fulfill its responsibilities and improve its processes.

Transparency: Clear communication of these aspects helps build trust and provides a basis for informed decision-making by the board.
