Which term is defined as the risk that controls, testing, or monitoring will fail to detect a material error?

• A. Inherent risk
• B. Detection risk
• C. Residual risk
• D. ROI

Answer: (B)

Detection risk is the possibility that material misstatements will slip through the organization’s controls or the auditor’s procedures and go undetected. This concept matters because even with strong controls and monitoring, there’s always some chance that an error isn’t caught, so testing and monitoring need to be designed to limit that risk. In the audit risk model, detection risk is addressed by adjusting the nature, timing, and extent of substantive testing — more rigorous procedures reduce detection risk when inherent risk and control risk are high, and less rigorous procedures allow detection risk to rise. That’s why detection risk is the term that fits the description. In contrast, inherent risk is the likelihood a misstatement could occur before controls, residual risk is what remains after controls, and ROI is unrelated to this risk concept.
