Which statement best describes the nature of a test of control?

• A. It is used to confirm that controls work and may reduce substantive testing.
• B. It is used when controls are not effective.
• C. It replaces substantive testing.
• D. It has no relation to the controls.

Answer: (A)

Tests of controls are procedures auditors perform to obtain evidence about whether internal controls over financial reporting are operating as designed. The aim is to determine if controls can be relied upon to prevent or detect material misstatements. When these tests show that controls are operating effectively, the audit can reduce the extent of substantive testing because less direct evidence is needed to support the financial statements. However, even with effective controls, some substantive procedures remain, especially in higher-risk areas or where fraud risk exists. This makes the statement describing tests of controls as used to confirm that controls work and potentially reduce substantive testing the best fit. It isn’t limited to situations where controls are ineffective, it doesn’t replace substantive testing, and it’s clearly related to controls.
