It is imperative for the chief audit executive to track and develop the educational qualifications of internal audit staff to ensure that the resources needed to complete the audit plan are available. By maintaining a well- qualified audit team, the CAE ensures that the internal audit activity is equipped to address the range of risks and controls that the audit plan encompasses, thereby fulfilling its responsibilities effectively.
IIA guidance on human resources management within internal audit, which emphasizes the importance of continuing education and staff development to meet the organization's audit needs.

The primary reason a chief audit executive should dedicate time and resources to the continuing professional development of internal audit staff is to ensure they have the competency to address high-priority risks.
Continuous professional development ensures that audit staff are equipped with up-to-date knowledge and skills necessary to effectively audit complex and evolving risk environments, thereby contributing directly to the effectiveness and reliability of the internal audit function.

* Option B: Matching cancelled checks to invoices ensures payment was made but does not specifically detect fictitious invoices.
* Option C: Searching for duplicate payments addresses duplicate invoices but not necessarily fictitious ones.
* Option D: Checking employee bank records could indicate fraud but is invasive and less direct than comparing addresses.

According to The IIA's Code of Ethics, objectivity must be maintained by internal auditors, which means they should not allow personal feelings or prejudices to affect their professional judgment. In this scenario, altering the audit program to focus on an issue because of personal disagreement over the treatment of workers demonstrates a failure to remain objective.
