Methods of gathering audit evidence include inspection (examining records or assets), observation (watching processes), external confirmation (third-party verification), recalculation (checking mathematical accuracy), reperformance (executing procedures), analytical procedures (evaluating financial data relationships), and inquiry (asking knowledgeable persons).

Alternatively, focusing on the purpose, they can be categorized as Financial Audits (financial statements), Compliance Audits (rules/regulations), and Operational Audits (efficiency/effectiveness).
Current best practices, such as the 5 Cs framework (Criteria, Condition, Cause, Consequence, and Corrective Action), ensure that audits provide actionable insights rather than simple observations.
