A chief audit executive (CAE) has no direct access to the board.

If a CAE has no direct access to the board, the most appropriate action, according to IIA guidance, is to maintain communication with the board through written communications. This method ensures that the board is informed of relevant audit findings and issues, upholding the governance role of the internal audit function even without direct access. This approach aligns with IIA standards on communicating and reporting to senior management and the board.

The Institute of Internal Auditors (IIA) - International Standards for the Professional Practice of Internal Auditing, specifically standards related to communication and reporting.
