Every audit committee should assess the effectiveness of the organization’s internal audit function at least annually, if not throughout the year. The critical role that internal audit plays requires the audit committee to ensure that the organization receives substantial benefits from the investments made in the internal audit function. Though the charter, scope, funding and activities of internal audit vary from company to company, audit committees should at least consider the following questions when evaluating their company’s internal audit function:
The evaluation of internal audit functions ranges from informal processes to formal, documented appraisals, including the use of outside advisors and the completion of a quality assessment review every five years, in accordance with the IIA Standards. Audit committees need to determine the appropriate scope and formality of this evaluation.
The audit committee should also receive an annual self-assessment on the internal audit function from the head of internal audit. This could be supplemented by discussions with management, external auditors and other stakeholders as relevant. It is essential that the evaluation process is understood and agreed upon by the board, audit committee and appropriate stakeholders.
