AUD Further Procedures, Testing, and Audit Evidence

This part covers the evidence-gathering stage of the audit. The emphasis is on selecting the right procedures, judging whether the evidence obtained is sufficient and appropriate, and understanding how findings shape the final audit conclusion.

In This Part

• Gathering Sufficient Appropriate Audit Evidence establishes the core evidence framework used throughout AUD.
• Testing Internal Controls and Evaluating Deviations shows how control testing affects reliance and further procedures.
• Substantive Testing of Accounts, Transactions, and Audit Cycles covers direct testing of balances, cycles, and assertions.
• Auditing Estimates, Related Parties, and Other Special Matters addresses higher-judgment areas where evidence quality matters most.
• Evaluating Misstatements and Concluding on Audit Results explains how identified issues are aggregated and assessed before reporting.

How to Use This Part

• Read this part after the planning chapters so procedure selection has context.
• Focus on what changes the nature, timing, and extent of testing for a specific assertion or risk.
• Return here whenever an AUD miss stems from choosing the wrong evidence response or drawing the wrong conclusion from test results.
