About this lesson

You'll discover the two main audit approaches—controls-based testing (where you rely on strong internal systems) and substantive testing (where you examine the numbers directly)—and when to use each one. The lesson covers practical techniques like walkthrough tests, sampling methods, and analytical review, all essential for the Audit and Assurance (AA) paper. By understanding these procedures, you'll be able to plan audit work efficiently, manage risk through sampling, and provide meaningful recommendations to improve business controls.
