Which audit type evaluates the effectiveness of internal control systems and processes?

• A. System-based audits
• B. Compliance testing
• C. Value for money audits
• D. Risk-based audits

Answer: (A)

System-based audits focus on the structure and operation of the internal control system as a whole, checking whether the design and operation of controls across processes effectively manage key risks. They examine components like the control environment, risk assessment, control activities, information and communication, and monitoring, and they test whether controls are actually working and whether any deficiencies are being remediated. This makes it the best answer to the question, because it directly targets evaluating internal controls themselves rather than just compliance with rules, value for money, or risk prioritization. Compliance testing, by contrast, verifies whether procedures are being followed, which is a check of compliance rather than overall control effectiveness. Value for money audits assess economy, efficiency, and effectiveness of programs rather than the control framework. Risk-based audits prioritize areas based on risk, but their main aim is to identify where to focus audit resources, not to comprehensively evaluate internal control systems.
