As part of a formal process of quality assurance, the Internal Audit function undergoes a Peer Review process. GAGAS requires that peer reviews be performed at least once every three years, while the IIA Standards require reviews at least once every five years. In order to conform to both GAGAS and IIA Standards, the AD has peer reviews performed every three years. The peer review takes the form of an internal self-assessment and independently validated by a qualified external reviewer. In order to facilitate and reduce the cost of an external review, a self-assessment will be performed within a short time prior to the external review. (For more information on Quality Assurance and Peer Review, see Procedures 270.00 and 270.00A)
