Which audit type confirms whether controls are operating effectively?

• A. Compliance testing
• B. Internal auditing
• C. Post-completion audits
• D. Quality audits

Answer: (A)

The key idea is how assurance activities verify that controls actually work in practice to meet policy or regulatory requirements. Compliance testing is used to check that controls are being applied as the policies require and that they operate effectively in day-to-day processes. By examining a sample of transactions or activities and seeing whether the control steps are followed and produce the expected outcome, you gain evidence that the control is functioning as intended and reducing risk. While internal auditing is the broader assurance function that may perform such tests, it isn’t a specific audit type focused on controls’ operating effectiveness. Post-completion audits look at project outcomes after delivery, and quality audits concentrate on product or process quality rather than whether controls are operating to policy. Hence, compliance testing is the most direct way to confirm that controls operate effectively.
