Control Deficiency vs Significant Deficiency vs Material Weakness
The categories differ by likelihood and magnitude of potential misstatement and the level of concern they create.
Control deficiency
A control deficiency exists when a control does not prevent or detect and correct misstatements on a timely basis as designed.
Significant deficiency
A significant deficiency is important enough to merit attention by those charged with governance but is less severe than a material weakness.
Material weakness
A material weakness creates a reasonable possibility that a material misstatement will not be prevented or detected and corrected timely.
Exam strategy
Focus on severity and potential financial-statement effect, not just whether a control failed.
The takeaway
Material weakness is the most severe category; significant deficiency is important but less severe.
