Core concepts
Concept 1
Sufficiency is the quantity of audit evidence; appropriateness is its relevance and reliability for the assertion and risk.
Exam cue: Match the procedure to the specific balance, assertion and assessed risk.
Concept 2
Inspection, observation, enquiry, confirmation, recalculation, reperformance and analytical procedures provide different evidence strengths.
Exam cue: Prefer independent, direct and documented evidence where available, while corroborating management explanations.
Concept 3
Sampling and data analytics help test populations, but design, completeness, selection and exception evaluation determine the conclusion.
Exam cue: Evaluate exceptions and control deviations before deciding whether more work or a changed approach is needed.
Risk pitfalls and guardrails
Using enquiry alone as sufficient evidence for a material assertion.
Guardrail: Do not rely on a familiar formula, tax rate, legal rule or policy until you confirm the period, entity, source data and current technical scope.
Performing a procedure that addresses existence when completeness is the risk.
Guardrail: Do not rely on a familiar formula, tax rate, legal rule or policy until you confirm the period, entity, source data and current technical scope.
Projecting from a biased or incomplete sample population.
Guardrail: Do not rely on a familiar formula, tax rate, legal rule or policy until you confirm the period, entity, source data and current technical scope.
Memory anchors
Sufficiency
Sufficiency concerns how much audit evidence is obtained.
Appropriateness
Appropriateness concerns evidence relevance and reliability.
Test of Control
A test of control evaluates whether a control operated effectively.
Substantive Procedure
A substantive procedure detects material misstatement at assertion level.
Audit Sampling
Audit sampling applies procedures to less than all items so a population conclusion can be formed.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
