What is auditing?
Audit and assurance assessment skills involve connecting a risk of misstatement to the relevant assertion, appropriate procedures and a conclusion supported by the evidence actually obtained. The worked questions cover existence versus completeness, searching for an omitted liability, a control design weakness, an unusual trend, an external response with a discrepancy, more items do not repair the wrong test. Use the explained answers to check your method, then practise applying the same principles to fresh facts instead of memorising an answer sequence.
Why this skill matters
Different testing directions answer different concerns. Finding listed inventory on the floor helps address existence; searching for items absent from the records addresses a different risk. An unusual trend or confirmation difference also requires investigation rather than automatic acceptance or accusation. The worked questions focus on these connections so that procedures have a stated purpose and exceptions receive an explained resolution.
A subject-specific method
Step 1
Describe what could be misstated and in which direction, then identify the assertion that the proposed procedure must address in the scenario.
Step 2
Choose the testing population and direction deliberately, distinguishing records-to-source existence work from source-to-records work directed toward completeness.
Step 3
Evaluate the relevance and reliability of evidence, considering its source, timing and the way it was obtained rather than simply counting documents.
Step 4
Investigate exceptions and contradictory evidence, recording an explained resolution instead of treating either management or an external response as automatically correct.
Step 5
Connect the conclusion to the evidence obtained and any remaining limitation, without claiming that one procedure resolves every assertion or the entire engagement.
Original worked scenario
Scenario: An accounts receivable balance is material, and several customer confirmations are unanswered. Task: Choose the best supported response or conclusion. Worked answer: Plan alternative procedures such as examining subsequent receipts and supporting sales documents; assess whether evidence is sufficient. Why this works: An unanswered confirmation does not by itself establish that a receivable is correct or incorrect. Appropriate alternative work can provide relevant evidence, depending on the assertion and circumstances. Subsequent receipts and sales records must be evaluated for what they support, with unresolved limitations considered in the engagement context. Common trap: A management assertion alone is not necessarily sufficient appropriate evidence.
How to prepare effectively
Prepare with a risk-to-procedure table. In one column describe a possible misstatement, such as an omitted supplier liability. In the next, identify evidence that could reveal an item missing from the listing. Then explain the period test needed to decide whether it belongs at year-end. This is more useful than memorising that auditors check invoices. Practise changing the assertion while keeping the account unchanged. A physical inventory count can help address recorded existence, but obsolescence requires a different line of enquiry. Asking for more of the same count evidence does not automatically answer a valuation question. Explain what new evidence would bear on the new concern. Use discrepancy exercises to develop follow-up reasoning. A confirmation difference, unexpected ratio or unmatched receiving record is not the end of the analysis. List plausible explanations, identify evidence that distinguishes them and document the resolution. Do not jump from an exception directly to an accusation or ignore it because the first explanation sounds reasonable. For controls, distinguish the design of a review from whether it actually operated. A policy assigning an independent reviewer does not prove that the reviewer performed the check for the transactions in question. Equally, one observed review does not establish consistent operation across a whole period. The scope of the evidence matters. Review answers for vague verbs. Replace verify, check or inspect alone with a clear population, evidence and purpose. In a formal assessment, follow the supplied engagement context and standards. The aim is a proportionate, reasoned response to risk, not the longest list of audit procedures you can recall.
Mistakes that reduce scores
An existence procedure does not automatically establish completeness, and more count evidence does not by itself resolve valuation. Do not treat an unusual trend as proof of fraud or a confirmation difference as an automatic ledger correction. Connect the evidence to the assertion and investigate exceptions before reaching the stated conclusion.
Frequently asked questions
Does records-to-floor testing establish completeness?
It most directly addresses existence of recorded items. Completeness requires considering items that may be missing from the records.
Does an analytical anomaly prove fraud?
No. It identifies a matter requiring investigation. Alternative explanations and supporting evidence determine the subsequent conclusion.
Can a larger sample solve an irrelevant test?
Not automatically. More existence evidence does not by itself answer an inventory valuation concern. Relevance and quantity are distinct.
How should I describe an audit procedure?
Identify the population, direction, evidence and assertion, then state any limitation. Avoid an unexplained instruction merely to check documents.
Audit and assurance: link a risk to evidence
Audit assessment questions often test whether a proposed procedure addresses a specific risk or assertion. Start by identifying what could be wrong and in which direction. An asset might not exist, an expense might be omitted, a valuation estimate might be unreasonable, or a transaction might be recorded in the wrong period. A procedure that answers one concern may provide little evidence about another. The corresponding production discipline is Audit & Assurance. The examples below teach selected evidence and risk concepts; they are not complete audit programmes. Actual engagements require the applicable standards, professional judgement, documentation and consideration of the entity's circumstances. Do not infer that completing one procedure automatically resolves an account balance or permits a particular audit opinion. IAASB's ISA 315 material emphasises identifying and assessing risks of material misstatement as a basis for an appropriate response. In practice questions, make that connection explicit: name the risk, identify the assertion and explain how the proposed evidence helps. More paperwork is not necessarily better evidence if it does not address the question being investigated.
Question 1: Existence versus completeness
An auditor selects items from an inventory listing and checks whether they are physically present at the count location. Which concern does that direction of testing most directly address? Answer: Existence of the recorded items. Starting from the list and finding the physical item helps test whether listed inventory is real. It does not by itself establish that every physical item has been included in the records. A floor-to-records direction can help address completeness. Both directions have limitations and require suitable procedures, but distinguishing them prevents an answer that claims one sample proves every inventory assertion.
Question 2: Searching for an omitted liability
The risk is that year-end supplier liabilities are understated because invoices for goods already received were omitted. Which evidence is more directly useful: inspecting only recorded payables, or examining relevant subsequent payments and unmatched receiving records? Answer: The latter provides a route to items that may be missing from the payables listing. Trace them to the underlying goods or services and determine the correct period. Testing only recorded liabilities can miss unrecorded ones. A subsequent payment is not automatically a year-end liability: it could relate to a later period, so the procedure needs supporting dates and evidence. The purpose is to investigate completeness, not mechanically accrue every later payment.
Question 3: A control design weakness
One employee can create a supplier, change its bank details, approve an invoice and release payment without independent review. What risk does this combination create, and what would a proposed improvement need to address? Answer: It concentrates incompatible powers and creates an opportunity for unauthorised or fraudulent payments. A response could separate relevant duties or introduce an effective independent review with appropriate evidence. Merely renaming the roles would not change the access or control operation. The scenario indicates a risk, not proof that fraud occurred. A control recommendation should be proportionate and should identify who checks what, when and with which authority.
Question 4: An unusual trend
Revenue rises 40% while recorded customer receipts rise 5%, and receivables increase sharply. Does this analytical observation prove fictitious sales? Answer: No. It identifies a relationship requiring investigation. Credit terms, growth timing, collection problems, cut-off errors or fictitious revenue are among possible explanations. Obtain relevant evidence and design further procedures rather than jumping from an anomaly to an accusation. Equally, a verbal explanation from management should be evaluated rather than automatically accepted. Analytical procedures become useful when the expectation, underlying data and follow-up are appropriate to the risk.
Question 5: An external response with a discrepancy
A customer's confirmation response disagrees with the recorded receivable. What should the auditor do before treating either amount as correct? Answer: Investigate the difference using appropriate evidence, such as transaction dates, remittances, credit notes and subsequent settlement. A discrepancy may reflect timing, an error or a disputed balance. The fact that a response is external does not remove the need to understand its relevance and reliability. Do not simply overwrite the ledger with the reply or discard the response because it conflicts with the books. Document the resolution and any implications for further work.
Question 6: More items do not repair the wrong test
The concern is whether recorded inventory is overstated because of obsolescence. A colleague proposes increasing the number of items counted physically, without examining condition, sales evidence or valuation. Does that alone address the valuation risk? Answer: No. More count evidence may strengthen the existence work but does not automatically establish recoverability or appropriate measurement. Procedures addressing condition, ageing, expected selling proceeds and relevant valuation requirements would be more directly connected to the stated concern. Evidence quantity and relevance are different dimensions. A large sample of the wrong evidence does not become sufficient merely through its size. The final audit response depends on all relevant risks and evidence, not this single example.
Preparing an audit answer that explains its purpose
Avoid vague instructions such as check the documents. State the population, selection direction, evidence and assertion. For example, tracing selected post-year-end payments to receiving dates is more informative than checking payments because it explains how the procedure can reveal an omitted year-end liability. Then identify any limitation: dates, authenticity, coverage or an alternative explanation that still needs investigation. Read the IAASB ISA 315 resource alongside the standards applicable to the engagement. In practice, distinguish an exposure draft or consultation from an effective requirement. Assessment preparation should develop reasoning about risk and evidence, not encourage a memorised audit programme applied without regard to the entity or reporting period.

A final practical check
An audit exception needs a recorded resolution, not merely a tick indicating that someone looked at it. Explain the evidence obtained, the conclusion reached and any effect on other procedures. An unresolved discrepancy should remain visible to the appropriate reviewer.
