Advanced expertise in internal auditing is largely based on the knowledge, skills, and abilities that are generally expected of all internal auditors. According to IIA guidance, all internal auditors should be proficient in risk management, control, and governance processes, including the ability to evaluate fraud risk and the ability to assess risk management strategies. However, creating test databases is a specialized technical skill that goes beyond the typical expertise of internal auditors. This type of skill is more commonly found among IT auditors or those with specific training in information technology, and it is not typically expected of all internal auditors.
