According to the IIA's International Professional Practices Framework (IPPF), internal auditors must possess the knowledge, skills, and other competencies needed to perform their individual responsibilities. This principle is embedded in the Attribute Standards, particularly Standard 1210 on Proficiency. Proficiency means internal auditors collectively must have the competencies necessary to carry out engagements. If the internal audit activity lacks certain skills, the Chief Audit Executive (CAE) must obtain competent advice and assistance from external sources or qualified experts. Key competency areas include understanding auditing standards, procedures, and techniques; knowledge of accounting principles; and awareness of management principles and business risks. Auditors must also be proficient in evaluating fraud risk, though they are not expected to have the expertise of a fraud investigation specialist. Additionally, they should understand information technology risks, controls, and available technology-based audit techniques. The IIA's Ethics component reinforces competency through the Code of Ethics, specifically the principle of Competency. This requires internal auditors to engage only in services for which they have the necessary knowledge, skills, and experience; to perform services in accordance with the International Standards; and to continually improve their proficiency, effectiveness, and quality of services. Continuing professional development (Standard 1230) is essential, requiring auditors to enhance their knowledge through ongoing education, professional certifications like the CIA, and staying current with industry developments. Due professional care (Standard 1220) complements competency, requiring auditors to apply the care and skill expected of a reasonably prudent and competent internal auditor. Together, these competency requirements ensure that internal auditors provide credible, objective, and value-adding services while upholding the profession's integrity, ultimately strengthening organizational governance, risk management, and control processes through skilled and ethical professional conduct.
Competency Requirements for Internal Auditors
Competency Requirements for Internal Auditors
Competency is a cornerstone of the internal audit profession. Understanding the competency requirements is essential for both practicing internal auditors and for candidates preparing for the CIA Part 1 exam, where this topic frequently appears under the domain of ethics and professionalism.
Why It Is Important
Competency ensures that internal auditors can perform their work with the necessary knowledge, skills, and abilities to add value and improve an organization's operations. Without competency, an audit engagement risks producing inaccurate conclusions, missing key risks, and eroding stakeholder confidence. The Global Internal Audit Standards (and the former IPPF) mandate competency as a condition for delivering credible, objective assurance. It is also directly tied to the IIA Code of Ethics, which lists Competency as one of its core principles. In short, competency protects the profession's reputation and the reliability of audit outcomes.
What It Is
Competency refers to the collective knowledge, skills, and other competencies (KSAs) needed to carry out internal audit responsibilities effectively. It applies at two levels:
1. Individual level: Each internal auditor must possess or obtain the knowledge, skills, and competencies needed for their assigned engagement. 2. Collective (function) level: The internal audit activity as a whole must possess, or obtain, the competencies needed to perform its responsibilities. The Chief Audit Executive (CAE) is responsible for ensuring this.
The IIA Code of Ethics states that internal auditors: • Shall engage only in those services for which they have the necessary knowledge, skills, and experience. • Shall perform internal audit services in accordance with the Standards. • Shall continually improve their proficiency and the effectiveness and quality of their services.
This last point reflects the requirement for Continuing Professional Development (CPD) or continuing professional education.
How It Works
Competency is applied and maintained through several mechanisms:
• Proficiency: Internal auditors must have sufficient knowledge to evaluate risks such as fraud and to understand how technology risks are managed, though they are not expected to have the expertise of those whose primary responsibility is detecting fraud or managing IT.
• Due Professional Care: Auditors apply the care and skill expected of a reasonably prudent and competent internal auditor. This does not imply infallibility.
• Obtaining competence: If the internal audit activity lacks certain competencies, the CAE may obtain competent advice and assistance from external service providers or hire staff with the needed skills.
• Continuing Professional Development: Auditors keep skills current through training, certifications (such as the CIA), and professional education.
• The CAE's role: The CAE must ensure the function collectively possesses the competencies to fulfill the audit plan, and must decline or supplement engagements where competency is lacking.
How to Answer Questions on This Topic in an Exam
Exam questions often test the distinction between individual and collective competency, the difference between proficiency and due professional care, and the appropriate response when competency is lacking (obtain outside help rather than proceed unqualified). Read scenarios carefully to identify whether the question concerns a single auditor or the whole function.
Remember that the correct action when a needed skill is missing is usually to obtain competent advice or assistance, not to simply decline the engagement or proceed anyway. Also recall that auditors are expected to have general awareness of fraud and IT risks but not to be specialists.
Exam Tips: Answering Questions on Competency Requirements for Internal Auditors
• Distinguish levels: Watch for whether the question refers to an individual auditor's competency or the internal audit activity's collective competency (a CAE responsibility).
• Proficiency vs. specialist expertise: Auditors need enough knowledge to recognize risks (e.g., fraud, IT) but are not expected to match specialists.
• Due professional care is not infallibility: Look for the phrase 'reasonably prudent and competent internal auditor' as the standard.
• Missing competency = obtain assistance: The best answer is typically to secure external or additional expertise rather than abandon or proceed unqualified.
• CPD is mandatory: Continuing professional development to improve proficiency is required, not optional.
• Link to the Code of Ethics: Recall that Competency is one of the four ethics principles alongside Integrity, Objectivity, and Confidentiality.
• Eliminate extremes: Answer choices suggesting auditors must guarantee results or be experts in every field are usually incorrect.
By mastering both the conceptual framework and these practical exam strategies, candidates can confidently handle competency-related questions on the CIA Part 1 exam.
