Which of the following best demonstrates internal auditors performing their work with proficiency?

Proficiency in internal auditing refers to possessing and maintaining the necessary knowledge, skills, and competencies. The most direct and demonstrable way auditors achieve this is through ongoing learning. The Institute of Internal Auditors (IIA) Standard 1230, "Continuing Professional Development," explicitly mandates that "Internal auditors must enhance their knowledge, skills, and other competencies through continuing professional development." Completing a CPD program is the primary mechanism for staying current with evolving risks, technologies, and auditing techniques, thereby actively demonstrating and maintaining the proficiency required by the Standards.

A. Meeting with management is a crucial part of audit communication and relationship management (related to IIA Standard 2400), not a direct demonstration of the auditor's underlying technical proficiency.
B. Adhering to the Code of Ethics is a fundamental requirement. While the Code includes a principle of Competency, completing CPD is the specific action that demonstrates the fulfillment of this principle.
C. Working collaboratively demonstrates teamwork and interpersonal skills. While these are valuable competencies, they do not encompass the full scope of technical knowledge and skills that define proficiency.

1. The Institute of Internal Auditors (IIA). (2017). International Standards for the Professional Practice of Internal Auditing.

Standard 1210: Proficiency: "Internal auditors must possess the knowledge, skills, and other competencies needed to perform their individual responsibilities."

Standard 1230: Continuing Professional Development: "Internal auditors must enhance their knowledge, skills, and other competencies through continuing professional development." This standard directly links the act of CPD to the maintenance of proficiency.

2. The Institute of Internal Auditors (IIA). (2017). The IIA's Code of Ethics.

Principle 4: Competency: "Internal auditors apply the knowledge, skills, and experience needed in the performance of internal audit services." Rule of Conduct 4.2 states auditors "Shall continually improve their proficiency and the effectiveness and quality of their services," which is achieved through activities like CPD.

3. Gramling, A. A., Rittenberg, L. E., & Johnstone, K. M. (2020). Auditing: A Risk-Based Approach (11th ed.). Cengage Learning.

Chapter 19, which discusses internal auditing, explains that professional standards, such as those from the IIA, require auditors to maintain their professional competence through continuing education to address the changing business environment and emerging risks. This reinforces that CPD is the recognized method for demonstrating proficiency.
