Use this guide to connect audit risks with assertions, controls, evidence and reporting decisions. The concepts progress from professional responsibilities to engagement completion, with examples aimed at entry-level CPA candidates. For each situation, identify the objective, explain why the procedure addresses it, and compare your reasoning with the resolved example.
Professional Responsibilities and Audit Foundations
1. Reasonable assurance and audit limitations
A financial statement audit seeks reasonable assurance that the statements are free of material misstatement, whether caused by fraud or error. Assurance is high but not absolute because evidence can be persuasive rather than conclusive, estimates involve uncertainty, and concealment can defeat procedures. These limitations do not justify accepting weak evidence for a significant risk.
Resolved example: A customer confirmation supports a receivable’s existence, but collection problems still require valuation evidence. The confirmation alone cannot establish that the balance is recoverable.
Mistake to avoid: Treating an audit opinion as a guarantee that every transaction is correct.
Context reference: What is the Uniform CPA Examination? - NASBA
2. Management and auditor responsibilities
Management prepares the financial statements, selects appropriate accounting policies and maintains relevant internal control. The auditor independently evaluates the statements and expresses an opinion based on evidence. Auditor recommendations do not transfer management’s decisions to the auditor. Distinguish responsibility for correcting an accounting record from responsibility for assessing its effect on the audit.
Resolved example: The auditor identifies omitted depreciation. Management evaluates and records the adjustment; the auditor tests the correction and considers whether similar omissions exist.
Mistake to avoid: Assuming that detecting an error makes the auditor responsible for preparing the accounts.
Context reference: What is the Uniform CPA Examination? - NASBA
3. Professional skepticism
Professional skepticism combines a questioning mind with critical assessment of evidence. It requires attention to contradictions, unusual circumstances and information that challenges management’s explanation. It does not mean assuming everyone is dishonest. Resolve inconsistencies through suitable corroboration, and reconsider earlier conclusions when new evidence changes the facts supporting them.
Resolved example: Management attributes rising revenue to higher prices, but invoices show unchanged prices. The auditor investigates quantities, returns and cutoff instead of accepting the original explanation.
Mistake to avoid: Accepting a plausible explanation without checking evidence that could contradict it.
Context reference: What is the Uniform CPA Examination? - NASBA
4. Professional judgment and objectivity
Professional judgment applies relevant knowledge and experience to the engagement’s facts. Objectivity requires avoiding bias, conflicts and undue influence when making that judgment. A defensible decision identifies alternatives, evaluates evidence and explains the conclusion. Neither seniority nor a preferred outcome substitutes for reasoning tied to the accounting framework and applicable professional requirements.
Resolved example: Two valuation assumptions are plausible. The auditor compares each with contracts and market evidence, then documents why one better reflects the entity’s circumstances.
Mistake to avoid: Choosing the assumption that produces the desired profit and rationalizing it afterward.
Context reference: What is the Uniform CPA Examination? - NASBA
5. Independence in fact and appearance
Independence concerns both an impartial state of mind and relationships that could reasonably undermine confidence in that impartiality. Financial interests, employment relationships and certain services can create problems even when an auditor believes personal judgment remains unbiased. Evaluate the relevant independence rules for the engagement before assuming that disclosure or another precaution resolves the relationship.
Resolved example: An engagement team member owns shares in the audit client. The firm checks the applicable prohibition and resolves the interest before permitting participation.
Mistake to avoid: Treating a personal promise of impartiality as sufficient evidence of independence.
Context reference: What is the Uniform CPA Examination? - NASBA
6. Ethical threats and appropriate responses
Ethical analysis identifies threats such as self-interest, self-review, advocacy, familiarity and intimidation. Evaluate their significance and determine the response permitted by applicable requirements. Some threats can be addressed through safeguards; prohibited relationships require eliminating the relationship or declining the work. A safeguard must change the circumstances creating the threat, rather than merely acknowledge them.
Resolved example: A client pressures an auditor to overlook unsupported revenue. Consultation and firm leadership involvement address the pressure while the auditor continues evaluating the disputed evidence.
Mistake to avoid: Assuming every ethical problem can be cured by disclosure or an extra review.
Context reference: What is the Uniform CPA Examination? - NASBA
7. Confidentiality and information handling
Confidentiality requires protecting client information and considering the basis for any disclosure. An engagement purpose does not authorize unrestricted sharing. Applicable professional requirements and law may establish exceptions or duties, so distinguish authorized disclosure from casual communication. Protect information during collection, storage, transmission and disposal, including when specialists or service providers are involved.
Resolved example: A valuation specialist needs contract data. The team confirms appropriate authorization and confidentiality arrangements, then shares only information relevant to the specialist’s work.
Mistake to avoid: Assuming that everyone working near the engagement may access all client records.
Context reference: What is the Uniform CPA Examination? - NASBA
8. Engagement acceptance and continuance
Acceptance and continuance decisions consider management integrity, independence, competence, resources and whether the engagement’s necessary conditions exist. A familiar client still requires reassessment when circumstances change. Serious restrictions on evidence access or doubts about integrity can affect whether the firm should undertake or continue the engagement under applicable professional requirements.
Resolved example: A returning client refuses access to major inventory records. The firm reassesses whether it can obtain sufficient evidence and whether continuing the engagement is appropriate.
Mistake to avoid: Treating last year’s acceptance decision as permanent despite changed circumstances.
Context reference: What is the Uniform CPA Examination? - NASBA
9. Agreeing the engagement terms
Clear engagement terms establish the objective, scope, applicable reporting framework and respective responsibilities. They also clarify expected reporting and access to relevant records and people. An engagement agreement reduces misunderstandings but does not override professional standards. Proposed restrictions should be evaluated before work begins, rather than silently incorporated into an otherwise unchanged audit.
Resolved example: A company requests an audit but permits only inquiry. The auditor explains that the proposed restriction prevents the evidence work needed for an audit.
Mistake to avoid: Assuming that a signed agreement makes an inadequate scope professionally acceptable.
Context reference: What is the Uniform CPA Examination? - NASBA
10. Documentation, supervision and review
Audit documentation connects procedures performed, evidence obtained and conclusions reached. It should allow an experienced auditor unfamiliar with the engagement to understand significant work and judgments. Supervision directs appropriate work; review evaluates whether it supports the conclusions. Significant contradictions and their resolution belong in the record, rather than only in informal conversations.
Resolved example: A reviewer finds two conflicting inventory totals. The preparer reconciles them and documents the source of the difference before concluding on the balance.
Mistake to avoid: Recording only a final checkmark without the evidence or reasoning supporting it.
Context reference: What is the Uniform CPA Examination? - NASBA
Planning and Risk Assessment
11. Understanding the entity and its environment
Risk assessment starts with understanding how the entity earns revenue, finances operations, uses technology and responds to external pressures. Business risks become audit concerns when they could cause material financial statement misstatements. Connect the economic circumstance to an account, disclosure or assertion instead of treating every business difficulty as an identical audit risk.
Resolved example: A retailer loses its main supplier. The auditor considers inventory availability, contract obligations and liquidity rather than automatically concluding that recorded sales are misstated.
Mistake to avoid: Listing business problems without explaining their possible financial statement effects.
Context reference: What is the Uniform CPA Examination? - NASBA
12. Financial statement assertions
Assertions describe what must be true about reported transactions, balances and disclosures. Relevant distinctions include existence or occurrence, completeness, rights and obligations, valuation, cutoff and presentation. Start with the possible misstatement, then identify the assertion at risk. One account can require different procedures because its existence, valuation and disclosure risks are separate.
Resolved example: A receivable may represent a real sale yet be uncollectible. Confirmation addresses existence more directly; subsequent receipts and credit information help address valuation.
Mistake to avoid: Assuming that proving an account exists proves every assertion about it.
Context reference: What is the Uniform CPA Examination? - NASBA
13. Materiality by size and nature
Materiality concerns whether a misstatement could reasonably influence financial statement users’ decisions. Amount matters, but nature and circumstances also matter. Relevant considerations can include sensitive disclosures, trends or compliance with contractual conditions. A planning amount guides audit work; it does not automatically make every smaller error immaterial in every setting.
Resolved example: A $6,000 error changes reported compliance with a loan covenant. Although small relative to assets, its effect requires qualitative evaluation.
Mistake to avoid: Using a numerical benchmark as the sole test of materiality.
Context reference: What is the Uniform CPA Examination? - NASBA
14. Performance materiality and aggregation
Performance materiality is set below overall materiality to reduce the risk that accumulated undetected and uncorrected misstatements exceed overall materiality. Its determination involves judgment about expected errors and engagement circumstances. It is not an allowed error quota for each account. Consider the combined effect of misstatements rather than evaluating every balance in isolation.
Resolved example: With overall materiality of $100,000, four uncorrected errors of $30,000 total $120,000. Their aggregate requires evaluation even though each is individually smaller.
Mistake to avoid: Comparing each error separately with overall materiality and ignoring their combined effect.
Context reference: What is the Uniform CPA Examination? - NASBA
15. Audit risk and detection risk
Audit risk is the risk of an inappropriate opinion when financial statements are materially misstated. Risks of material misstatement reflect inherent and control risk; detection risk concerns audit procedures failing to detect a misstatement. When assessed misstatement risk rises, the auditor needs procedures capable of lowering detection risk through more persuasive evidence.
Resolved example: Weak controls and complex revenue terms increase assessed risk. The auditor responds with closer contract inspection and more direct testing of recognition.
Mistake to avoid: Believing that strong audit procedures change the client’s underlying inherent risk.
Context reference: What is the Uniform CPA Examination? - NASBA
16. Inherent risk factors
Inherent risk concerns susceptibility to misstatement before considering related controls. Complexity, subjectivity, uncertainty, change and susceptibility to bias can increase that susceptibility. Assess these factors at the relevant assertion level. A large balance is not necessarily difficult to audit, while a smaller estimate can contain substantial uncertainty or require specialized knowledge.
Resolved example: A fixed bank deposit has straightforward terms. A smaller contingent payment depends on uncertain future sales and therefore presents greater estimation complexity.
Mistake to avoid: Ranking inherent risk solely by account size without examining how the amount is determined.
Context reference: What is the Uniform CPA Examination? - NASBA
17. Fraud risk and management override
Fraud involves intentional misstatement, including fraudulent reporting or asset misappropriation. Incentives, opportunities and rationalizations inform assessment but do not prove fraud. Management override deserves attention because management can bypass otherwise effective controls. Journal entries, biased estimates and unusual transactions warrant procedures responsive to the circumstances, rather than a presumption that all unusual items are fraudulent.
Resolved example: Large period-end revenue entries lack normal shipment references. The auditor investigates their authorization, business purpose and supporting evidence before drawing a conclusion.
Mistake to avoid: Treating a fraud indicator as proof, or dismissing override because routine controls work.
Context reference: What is the Uniform CPA Examination? - NASBA
18. Risk assessment procedures
Inquiry, analytical procedures, observation and inspection help identify and assess risks. Combine sources because an explanation from management may differ from operational evidence. Risk assessment establishes where further work is needed; it generally does not, by itself, provide all the evidence necessary for an audit opinion. Document how findings change the planned response.
Resolved example: Inquiry suggests stable margins, but preliminary analysis shows a sharp increase. Inspection identifies a new revenue arrangement requiring additional recognition testing.
Mistake to avoid: Treating preliminary analytical relationships as conclusive evidence that balances are fairly stated.
Context reference: What is the Uniform CPA Examination? - NASBA
19. Nature, timing and extent of procedures
Nature means the type and purpose of a procedure; timing means when it is performed or which period it covers; extent means its quantity or coverage. Responding to risk can change any of these dimensions. More items do not compensate for an irrelevant procedure, and interim work needs appropriate attention to the remaining period.
Resolved example: For risky year-end sales, inspecting contracts and shipment evidence near year-end is more responsive than doubling an unrelated midyear expense sample.
Mistake to avoid: Equating a stronger audit response exclusively with a larger sample.
Context reference: What is the Uniform CPA Examination? - NASBA
20. Updating the audit strategy and plan
The audit strategy establishes overall scope, timing and direction; the plan describes procedures that implement it. Both respond to new information. An unexpected control failure or unusual transaction can require revising assessed risks, staffing and substantive work. Preserve the connection between the changed fact, revised assessment and resulting procedure rather than updating paperwork without changing work.
Resolved example: A late acquisition introduces unfamiliar valuation issues. The team adds specialist involvement and acquisition testing to address the new risks.
Mistake to avoid: Following the original plan unchanged after evidence undermines its assumptions.
Context reference: What is the Uniform CPA Examination? - NASBA
Internal Control and Control Testing
21. The interconnected components of internal control
Internal control encompasses the control environment, risk assessment, control activities, information and communication, and monitoring. These components work together rather than as isolated checklists. A well-designed approval can be undermined by poor information or a culture that tolerates bypassing it. Understand how controls address relevant reporting risks and how the organization detects failures.
Resolved example: Managers approve credit limits, but sales staff routinely ignore them without follow-up. The formal approval does not establish an effective overall control process.
Mistake to avoid: Evaluating written procedures without considering behavior, information flows and monitoring.
Context reference: What is the Uniform CPA Examination? - NASBA
22. Control design versus implementation
Design asks whether a control could prevent, or detect and correct, a relevant misstatement if properly operated. Implementation asks whether the control actually exists and is being used. Neither establishes consistent operation throughout the period. A walkthrough can help understand design and implementation, but additional evidence is needed when the audit relies on operating effectiveness.
Resolved example: A purchase approval policy is suitable, but staff never use it. The control has a design on paper without effective implementation.
Mistake to avoid: Treating a policy manual as evidence that a control operated.
Context reference: What is the Uniform CPA Examination? - NASBA
23. Segregation of incompatible duties
Separating authorization, custody, recording and reconciliation reduces opportunities to commit and conceal errors or fraud. Evaluate actual access and responsibilities, including electronic permissions. Small organizations may use compensating controls, but those controls need sufficient independence and precision. Different job titles do not create segregation when one person can perform all critical functions.
Resolved example: A clerk creates vendors and releases payments. Independent approval of new vendors and payment review can address the risk if effectively performed.
Mistake to avoid: Assuming separate departments provide segregation despite shared credentials or unrestricted access.
Context reference: What is the Uniform CPA Examination? - NASBA
24. Authorization controls
Authorization controls establish that transactions receive appropriate approval before execution or recording. Assess who approves, what information is reviewed and whether exceptions are resolved. A signature is useful only if it represents a meaningful decision by an authorized person. Approval also has limits: it does not automatically establish correct accounting or actual receipt of goods.
Resolved example: A purchasing manager approves an order within delegated authority. The auditor still examines receiving evidence before concluding that the related expense occurred.
Mistake to avoid: Treating approval as proof of every financial statement assertion.
Context reference: What is the Uniform CPA Examination? - NASBA
25. Reconciliations and management review controls
A reconciliation compares independent records, identifies differences and ensures appropriate resolution. A review control needs sufficient precision to detect the misstatements it targets. Consider the reviewer’s expectations, investigation criteria and evidence of follow-up. A broad review of total expenses may not detect offsetting errors within individual accounts.
Resolved example: A bank reconciliation flags a $9,400 unexplained difference. The reviewer traces it to a duplicate book entry and confirms correction before approval.
Mistake to avoid: Counting a completed reconciliation as effective when unexplained differences remain unresolved.
Context reference: What is the Uniform CPA Examination? - NASBA
26. General information technology controls
General IT controls support reliable system operation through access management, program change controls and operational controls. Their relevance depends on the systems and automated controls used in the audit. Weak access or change controls can undermine reliance on otherwise well-designed applications. Assess the affected functionality rather than assuming every IT weakness has an identical financial reporting effect.
Resolved example: Developers can alter live pricing code without approval. The auditor reassesses reliance on automated invoice calculations and tests affected transaction amounts directly.
Mistake to avoid: Assuming an automated control stays reliable merely because its original configuration was correct.
Context reference: What is the Uniform CPA Examination? - NASBA
27. Application controls and exception handling
Application controls operate within transaction processing, including validation, duplicate checks and matching routines. Determine which errors the control can identify and what happens to rejected or flagged items. An automated warning is not an effective correction process unless someone appropriately resolves it. Controls over changes and access also affect confidence in automated operation.
Resolved example: The system flags duplicate invoice numbers, but users can override warnings freely. The auditor evaluates override controls before relying on duplicate prevention.
Mistake to avoid: Treating the presence of an error message as proof that invalid transactions cannot proceed.
Context reference: What is the Uniform CPA Examination? - NASBA
28. Service organizations and report scope
Outsourced processing remains relevant to the user entity’s reporting risks. Evaluate available service auditor reports for the controls covered, period, testing and exceptions. A report addressing financial reporting controls may support different conclusions from one addressing security or availability. Consider any complementary controls the user entity must operate and gaps between report coverage and the audit period.
Resolved example: A payroll provider’s report assumes clients approve employee changes. The auditor tests the company’s approval process instead of assuming outsourcing covers it.
Mistake to avoid: Relying on a service report without checking its purpose, period and user responsibilities.
Context reference: What is the Uniform CPA Examination? - NASBA
29. Testing operating effectiveness
Tests of controls evaluate whether relevant controls operated as designed, by appropriate people, over the period of intended reliance. Evidence can include inspection, observation and reperformance; inquiry alone generally provides insufficient support for operating effectiveness. Testing at one date may not support reliance across a year, especially when personnel, systems or procedures changed.
Resolved example: The auditor reperforms selected monthly reconciliations and inspects review follow-up across the year. This supports a broader conclusion than observing one reconciliation.
Mistake to avoid: Extending a single successful observation to the entire period without justification.
Context reference: What is the Uniform CPA Examination? - NASBA
30. Control deficiencies and audit consequences
A control deficiency exists when design or operation fails to address a relevant misstatement risk adequately. Evaluate significance using likelihood and potential magnitude, including interaction with other deficiencies. Classification and communication depend on the applicable engagement standards. A deficiency can require changing audit procedures even when no actual material misstatement has yet been found.
Resolved example: No one reviews manual revenue entries. The auditor increases direct journal-entry testing and evaluates the deficiency for communication under the relevant standards.
Mistake to avoid: Concluding that a control is adequate solely because testing found no misstatement.
Context reference: What is the Uniform CPA Examination? - NASBA
Audit Evidence and Sampling
31. Sufficiency and appropriateness of evidence
Sufficiency concerns the quantity of evidence; appropriateness concerns relevance and reliability. Required quantity depends partly on risk and evidence quality. Large volumes of irrelevant or unreliable material do not establish an assertion. Before expanding testing, ask whether the selected procedure addresses the possible misstatement and whether the information used can be trusted.
Resolved example: Hundreds of purchase orders show authorization but not delivery. Receiving records provide more relevant evidence for whether goods were received.
Mistake to avoid: Counting documents without evaluating the assertion each document supports.
Context reference: What is the Uniform CPA Examination? - NASBA
32. Evidence reliability and entity-produced information
Evidence reliability depends on its source, nature and circumstances. Directly obtained independent evidence is often persuasive, but general reliability tendencies are not absolute rules. Reports produced by the entity require attention to completeness, accuracy and detail. A genuine document may still be irrelevant to the period or assertion being tested.
Resolved example: Before analyzing overdue receivables, the auditor reconciles the aging report to the ledger and tests whether invoice dates and balances are accurate.
Mistake to avoid: Assuming a professionally formatted system report is automatically complete and accurate.
Context reference: What is the Uniform CPA Examination? - NASBA
33. Vouching and tracing
The direction of testing determines which omissions or overstatements a procedure can detect. Vouching generally starts with recorded items and seeks supporting evidence, helping test occurrence or existence. Tracing generally starts with source evidence and follows it into records, helping test completeness. Choose an appropriate source population and investigate missing or inconsistent links.
Resolved example: To find omitted sales, the auditor traces dispatched orders into the sales ledger. Starting only with recorded sales would miss orders never entered.
Mistake to avoid: Using a recorded-item sample to conclude that unrecorded transactions do not exist.
Context reference: What is the Uniform CPA Examination? - NASBA
34. External confirmations
External confirmations seek information directly from a knowledgeable third party, with the auditor maintaining appropriate control over requests and responses. Evaluate authenticity, exceptions and nonresponses. A nonresponse is not agreement with the recorded amount. Alternative procedures must address the relevant assertion, and confirmation evidence may not resolve valuation, completeness or contractual issues by itself.
Resolved example: A customer does not respond about a $14,000 balance. The auditor examines subsequent receipts, invoices and delivery evidence relevant to the outstanding amount.
Mistake to avoid: Treating silence as confirmation or accepting responses routed through management without evaluation.
Context reference: What is the Uniform CPA Examination? - NASBA
35. Substantive analytical procedures
A substantive analytical procedure compares recorded amounts with a sufficiently precise expectation developed from reliable data and plausible relationships. Determine an acceptable difference and investigate discrepancies with corroborating evidence. Relationships may weaken when pricing, product mix or operations change. A broad trend comparison can identify risk without being precise enough to provide substantive assurance.
Resolved example: A stable lease requires $8,000 monthly rent for twelve months, suggesting $96,000. Recorded rent of $112,000 requires investigation of additional premises or errors.
Mistake to avoid: Accepting management’s explanation for a difference without supporting evidence.
Context reference: What is the Uniform CPA Examination? - NASBA
36. Defining populations and selecting samples
A sampling conclusion applies to the population from which the sample was selected. Define the objective, sampling unit, period and relevant population before choosing items. Statistical and nonstatistical approaches both require thoughtful selection and evaluation. Separately testing large or unusual items can be useful, but those results do not automatically represent the remaining population.
Resolved example: Testing ten largest invoices identifies their individual accuracy. It does not establish the error rate among thousands of smaller invoices.
Mistake to avoid: Projecting results from convenient or targeted items to an unrelated population.
Context reference: What is the Uniform CPA Examination? - NASBA
37. Sampling and nonsampling risk
Sampling risk is the possibility that a sample leads to a different conclusion from examining the entire population. Nonsampling risk arises from inappropriate procedures, misinterpreted evidence or failure to recognize errors. A larger sample can reduce sampling risk, but it does not repair a poorly designed procedure or an incorrectly defined population.
Resolved example: Testing more invoices does not detect omitted shipments when the auditor samples only recorded invoices. The completeness objective requires a different population.
Mistake to avoid: Assuming that increasing sample size solves every weakness in audit testing.
Context reference: What is the Uniform CPA Examination? - NASBA
38. Evaluating control sample deviations
A control deviation is a failure to perform the control as specified. Evaluate its cause, frequency and implications for intended reliance, including sampling risk. The observed deviation rate is not necessarily the population’s true rate. Consider whether deviations cluster around particular employees, periods or transaction types and whether alternative controls address the same risk.
Resolved example: Three missing approvals in sixty tested items give an observed deviation rate of 5%. The auditor evaluates uncertainty and causes before deciding on reliance.
Mistake to avoid: Treating the observed rate as exact or assuming extra clean items erase deviations.
Context reference: What is the Uniform CPA Examination? - NASBA
39. Projecting substantive sample misstatements
Substantive sampling evaluates detected misstatements and, where appropriate, projects them to the sampled population using a suitable method. Separate known errors, projected errors and sampling uncertainty. Projection does not establish the exact population misstatement. Investigate error causes and consider whether the sample remains representative before comparing the results with relevant tolerable amounts.
Resolved example: Under ratio projection, $1,200 error in a $60,000 sample from a $600,000 population projects to $12,000, before considering sampling uncertainty.
Mistake to avoid: Reporting a projection as an exact error or applying it to separately tested items.
Context reference: What is the Uniform CPA Examination? - NASBA
40. Written representations
Written representations document management’s acknowledgment of responsibilities and statements about relevant matters. They support other audit evidence but do not replace evidence reasonably expected to be available. Contradictory evidence requires resolution even when a representation is signed. Refusal to provide necessary representations raises questions about evidence sufficiency and management integrity under applicable standards.
Resolved example: Management states that inventory is usable, but inspection finds widespread damage. The auditor investigates recoverability rather than relying on the representation.
Mistake to avoid: Using a signed management statement to dismiss contradictory objective evidence.
Context reference: What is the Uniform CPA Examination? - NASBA
Accounts and Transaction Cycles
41. Cash and bank reconciliations
Cash testing distinguishes bank-side timing differences from missing or incorrect book entries. Inspect reconciliations, verify significant reconciling items and consider restrictions or transfers affecting presentation and cutoff. Deposits in transit and outstanding checks require evidence of subsequent clearing or another explanation. A reconciled total does not establish that every reconciling item is legitimate.
Resolved example: Bank cash of $52,000 plus $7,000 in transit less $4,000 outstanding checks equals $55,000. Books of $55,300 need a verified $300 bank-charge adjustment.
Mistake to avoid: Accepting old reconciling items without investigating why they have not cleared.
Context reference: What is the Uniform CPA Examination? - NASBA
42. Inventory observation and count testing
Inventory count work addresses physical quantities and condition while considering movement during the count and the entity’s counting procedures. Test from count records to goods for existence and from goods to records for completeness. Observation alone does not establish ownership or valuation. Reconcile tested count information with final inventory records and investigate significant adjustments.
Resolved example: An unlisted pallet is found on the warehouse floor. Tracing it into final count records addresses completeness; ownership documents establish whether it belongs to the entity.
Mistake to avoid: Treating physical possession as proof of ownership or correct valuation.
Context reference: What is the Uniform CPA Examination? - NASBA
43. Inventory costing and recoverability
Inventory valuation requires testing cost accumulation and applying the entity’s relevant reporting framework to recoverability. Obsolescence, damage and slow movement can indicate that recorded cost is not recoverable. Subsequent sales can provide useful evidence when circumstances are comparable. Do not assume every inventory method uses the same subsequent-measurement rule.
Resolved example: Under an applicable lower-of-cost-and-net-realizable-value policy, an item costs $90 and has $72 net realizable value. The required write-down is $18.
Mistake to avoid: Applying a valuation formula without identifying the framework and inventory method.
Context reference: What is the Uniform CPA Examination? - NASBA
44. Revenue recognition and cutoff
Revenue testing connects accounting recognition to contractual performance under the applicable framework. Invoice dates and cash receipts do not independently establish when revenue belongs in the statements. Inspect delivery, acceptance, service completion and return terms as relevant. Cutoff testing around period-end helps detect transactions recorded in the wrong reporting period.
Resolved example: A contract requires customer acceptance, which occurs on January 4. A December 29 invoice alone does not support December recognition when acceptance remains substantive.
Mistake to avoid: Using the invoice date as a universal revenue recognition rule.
Context reference: What is the Uniform CPA Examination? - NASBA
45. Receivables and credit loss estimates
Receivables require distinct evidence about existence, rights and expected collection. Confirmation or delivery documentation may support existence, while subsequent receipts, aging, disputes and credit information inform recoverability. Evaluate the applicable credit loss approach and management’s assumptions. A customer’s agreement with a balance does not establish that the customer can or will pay it.
Resolved example: A customer confirms a $40,000 receivable but enters financial distress. The auditor evaluates credit loss evidence rather than concluding that confirmation proves full recovery.
Mistake to avoid: Confusing acknowledgment of a debt with evidence of collectibility.
Context reference: What is the Uniform CPA Examination? - NASBA
46. Searching for unrecorded liabilities
Liability completeness testing looks beyond recorded payables for obligations that should have been recognized. Subsequent payments, supplier statements, unmatched receiving reports and unpaid invoices can reveal omissions. Determine whether the underlying goods or services were received before period-end and apply the relevant recognition rules. Payment after year-end does not automatically mean a current-year expense.
Resolved example: A January payment covers materials received December 27. Inspection identifies a year-end payable that was omitted from the December records.
Mistake to avoid: Testing only listed payables when the risk is liabilities missing from the list.
Context reference: What is the Uniform CPA Examination? - NASBA
47. Payroll validity and accrued compensation
Payroll testing addresses whether employees are genuine, compensation is authorized and recorded amounts reflect work or entitlements under the applicable arrangements. Compare payroll records with personnel records and independent evidence of employment. Period-end accrual testing separates payment date from when compensation was earned. Current statutory rates or entitlements require confirmation rather than assumption.
Resolved example: Employees earn $18,000 before year-end but receive payment in January. If unpaid and unrecorded, the auditor identifies an omitted compensation accrual.
Mistake to avoid: Assuming a bank transfer proves the recipient was a valid employee.
Context reference: What is the Uniform CPA Examination? - NASBA
48. Property, equipment and capitalization
Testing property and equipment includes additions, disposals, ownership, depreciation and possible impairment. Distinguish costs qualifying for capitalization from ordinary operating expenses under the reporting framework. Inspect supporting documents and assess whether useful lives, residual values and depreciation methods remain appropriate. Physical inspection supports existence but does not determine correct carrying value.
Resolved example: A company capitalizes routine machine cleaning. The auditor evaluates its nature and identifies expense treatment when it creates no qualifying asset or improvement.
Mistake to avoid: Capitalizing a payment solely because it relates to an existing fixed asset.
Context reference: What is the Uniform CPA Examination? - NASBA
49. Auditing estimates and management bias
Estimate testing evaluates methods, significant assumptions and data in light of the applicable measurement objective. Possible approaches include testing management’s process, developing an independent expectation or considering relevant subsequent events. Estimation uncertainty does not make every outcome acceptable. Assess patterns suggesting bias across estimates, even where individual assumptions appear plausible.
Resolved example: Management consistently chooses optimistic demand assumptions across several valuations. The auditor evaluates their support and the combined indication of bias.
Mistake to avoid: Accepting an estimate simply because its calculation is mathematically correct.
Context reference: What is the Uniform CPA Examination? - NASBA
50. Contingencies, commitments and legal evidence
Contingencies and commitments require evidence about underlying obligations, uncertainty and disclosure, using the applicable reporting framework. Relevant sources can include contracts, minutes, correspondence, legal expenses and appropriately obtained legal responses. Recognition and disclosure thresholds differ across frameworks. A missing recorded liability does not establish that there is no reportable obligation.
Resolved example: Board minutes describe a guarantee absent from the ledger. The auditor inspects the agreement and evaluates required recognition or disclosure.
Mistake to avoid: Assuming legal uncertainty always means neither recognition nor disclosure is needed.
Context reference: What is the Uniform CPA Examination? - NASBA
Completion, Reporting and Other Engagements
51. Evaluating uncorrected misstatements
Completion requires evaluating identified uncorrected misstatements individually and together, considering size, nature and circumstances. Consider relevant prior-period effects and whether findings suggest additional undetected errors. Revisit materiality if actual results differ substantially from planning assumptions. Offsetting errors do not automatically disappear because their net effect on profit is small.
Resolved example: Revenue and expenses are each overstated by $70,000. Net profit is unchanged, but both line items and related disclosures still require materiality evaluation.
Mistake to avoid: Assessing only the net effect on earnings while ignoring other statement effects.
Context reference: What is the Uniform CPA Examination? - NASBA
52. Subsequent events and relevant dates
Subsequent events can provide evidence about conditions existing at the reporting date or reveal conditions arising afterward. The distinction affects adjustment or disclosure under the applicable framework. Audit responsibilities also depend on when the event becomes known relative to the report date and release. Establish the chronology before deciding what accounting or audit action is appropriate.
Resolved example: January insolvency confirms a customer’s severe December financial problems. That evidence informs the year-end receivable estimate rather than being dismissed as entirely new.
Mistake to avoid: Classifying every post-year-end event as irrelevant to year-end measurement.
Context reference: What is the Uniform CPA Examination? - NASBA
53. Going concern evidence and reporting
Going concern evaluation considers conditions raising doubt about continued operations, management’s plans and evidence supporting those plans. A forecast needs credible assumptions about financing, cash flows and obligations. Evaluation periods and reporting terminology depend on the applicable framework and standards. Financial difficulty does not automatically dictate one opinion; disclosure adequacy and audit evidence also matter.
Resolved example: A forecast assumes loan renewal, but the lender has rejected renewal. The auditor challenges the forecast and evaluates alternative financing evidence.
Mistake to avoid: Treating an unsupported management plan as sufficient to resolve going concern concerns.
Context reference: What is the Uniform CPA Examination? - NASBA
54. The basis for an unmodified opinion
An unmodified opinion communicates that the financial statements are presented fairly, in all material respects, under the identified framework. It requires sufficient appropriate evidence and appropriate reporting under the applicable standards. It does not certify business success, eliminate uncertainty or promise fraud detection. Read the opinion together with its framework and the statements it covers.
Resolved example: A company reports a substantial loss accurately and with adequate disclosures. The loss itself does not prevent an unmodified opinion.
Mistake to avoid: Assuming that unfavorable financial results necessarily require a modified audit opinion.
Context reference: What is the Uniform CPA Examination? - NASBA
55. Choosing a modified opinion
Distinguish identified material misstatement from inability to obtain sufficient appropriate evidence. A material but nonpervasive issue generally leads to qualification. Material and pervasive misstatement supports an adverse opinion; material and pervasive possible effects of missing evidence support a disclaimer. Pervasiveness concerns the reach or fundamental significance of effects, rather than a universal numerical percentage.
Resolved example: Known pervasive inventory valuation errors support an adverse opinion; inability to audit pervasive inventory effects points toward a disclaimer.
Mistake to avoid: Choosing adverse versus disclaimer solely by severity without distinguishing misstatement from missing evidence.
Context reference: What is the Uniform CPA Examination? - NASBA
56. Emphasis-of-matter and other-matter paragraphs
Under applicable standards, an emphasis-of-matter paragraph draws attention to a matter appropriately presented or disclosed in the financial statements that is fundamental to understanding them. An other-matter paragraph concerns matters outside the statements relevant to understanding the audit, responsibilities or report. Neither replaces a necessary modified opinion or another specifically required reporting section.
Resolved example: A properly disclosed exceptional event may warrant emphasis. A material disclosure omission instead requires evaluating an opinion modification.
Mistake to avoid: Using an emphasis paragraph to compensate for inadequate financial statement disclosure.

57. Audit, review and compilation distinctions
A financial statement audit provides reasonable assurance through risk-responsive evidence work. A review provides limited assurance, generally using inquiry and analytical procedures, with further work when needed. A compilation assists financial statement presentation without providing assurance. Select the engagement’s actual requirements rather than treating these services as interchangeable versions of the same report.
Resolved example: A lender requires audited statements. A compilation report does not satisfy that assurance request merely because the same accountant prepared it.
Mistake to avoid: Assuming any accountant-associated financial statement includes an assurance opinion.

58. Attestation criteria and agreed-upon procedures
Attestation work evaluates subject matter against suitable criteria under the relevant standards. Examination and review engagements provide different assurance levels. Agreed-upon procedures report procedures and findings without an assurance opinion or conclusion. Clear criteria and precisely described procedures prevent ambiguity about what was evaluated and what readers can reasonably infer from the report.
Resolved example: An agreed procedure compares grant spending with invoices. The report states the differences found; it does not conclude that all grant requirements were met.
Mistake to avoid: Turning narrowly defined factual findings into a broad compliance assurance conclusion.

59. Reporting frameworks and applicable standards
Accounting frameworks determine how transactions are recognized, measured and presented; auditing standards govern the auditor’s work and reporting. Identify both before resolving a scenario. Entity and engagement characteristics affect which standards apply. A special-purpose framework requires attention to suitability, presentation and reporting considerations rather than automatic use of general-purpose reporting assumptions.
Resolved example: Statements use a cash-basis framework. The auditor evaluates that identified framework and reporting requirements instead of automatically demanding accrual-basis presentation.
Mistake to avoid: Confusing an accounting recognition rule with an auditing procedure or reporting requirement.

60. Completion review and governance communication
Completion brings together evidence, significant judgments, overall analytical review and communications with those charged with governance. Investigate whether the final statements remain consistent with the auditor’s understanding. Communicate significant matters as required by applicable standards, distinguishing governance responsibilities from management’s operational role. Communication complements evidence evaluation rather than replacing unresolved audit work.
Resolved example: Final analysis shows unexpectedly high margins despite known pricing pressure. The auditor investigates the inconsistency before concluding and communicates significant findings appropriately.
Mistake to avoid: Treating a closing meeting as a substitute for resolving contradictory evidence.
