Internal Control Effectiveness Assessment

Overview

Evaluate the design and operating effectiveness of internal controls using the COSO Internal Control Framework (2013 revision, 17 principles), SOX Section 302/404 requirements, and the Three Lines of Defense model. This skill supports the assessment of control test results, identification of deficiencies, and determination of whether deficiencies constitute significant deficiencies or material weaknesses.

When to Use

• Evaluating control testing results from first-line, second-line, or third-line testing programs
• Assessing whether control design adequately addresses identified risks
• Determining the severity of control deficiencies (deficiency, significant deficiency, material weakness)
• Preparing or reviewing management's annual assessment of internal controls (SOX 404)
• Analyzing trends in control effectiveness across business units or risk domains
• Responding to external audit findings on control effectiveness
