D251 Advanced Auditing is a graduate course in Western Governors University's Master of Accounting that revisits core audit concepts and then applies them to real transaction cycles.
WGU's program guide describes two parts. The first reviews planning (identifying, assessing and responding to the risk of material misstatement), specialized tools (attributes sampling, monetary unit sampling and data analytics), completing a quality audit and reporting.
The second applies auditing to the acquisition and payment cycle, then carries that knowledge to the revenue cycle in a performance assessment.
It carries three competency units in the MACC guides. The step up from undergraduate auditing is mainly in sampling and in writing about a full cycle audit coherently.

Key Concepts Explained
Materiality
Materiality is the size of misstatement that would change a reasonable user's decision. Auditors set overall materiality from a benchmark (such as pre-tax income or revenue) and a lower performance materiality to allow for undetected errors.
Attributes Sampling Versus Monetary Unit Sampling
Attributes sampling estimates a rate of deviation, so it suits tests of controls. Monetary unit sampling (MUS) treats each dollar as a sampling unit, so larger balances are more likely to be selected; it suits tests of details aimed at overstatement.
Example: Testing whether purchase invoices were approved, an auditor samples 60 invoices and finds 2 without approval: a sample deviation rate of about 3.3 percent. If the tolerable rate is 5 percent, the auditor compares the computed upper deviation limit (from sampling tables) with 5 percent before relying on the control. The sample rate alone is not enough.
Search for Unrecorded Liabilities
In the acquisition and payment cycle, the bigger risk is understatement of payables. Auditors examine payments made after year end and unpaid invoices to find liabilities that belong in the current period.
Typical Assignments and How to Approach Them
| Task type | What it tests | How to approach it |
|---|---|---|
| Materiality calculation | Benchmark and judgment | Justify the benchmark, not just the percentage |
| Sampling question | Method choice and evaluation | Match method to objective; evaluate the upper limit |
| Cycle audit write-up | Risks, controls and tests | Use one structure: risk, assertion, control, test, result |
| Report question | Choosing the right report | Decide materiality and pervasiveness first |
Data Analytics in the Audit
The course names data analytic tools alongside traditional sampling. Analytics let an auditor examine whole populations rather than samples, for example sorting every payment to find duplicates, payments to suppliers not on the approved list, or invoices dated on weekends.
When writing about analytics, explain what population you tested, what rule identified exceptions and what you did with the exceptions. Analytics flag items; the auditor still has to investigate and conclude.
Where Students Get Stuck
- Sample results without evaluation. Always compare the projected or upper limit with the tolerable amount.
- Testing the wrong direction. Payables risk is usually understatement; tests must look for what is missing.
- Disconnected write-ups. Each test should trace back to a named risk and assertion.
- Reporting choices. Practice deciding between qualified, adverse and disclaimer.
Study Tips for D251
- Revise your D215 or undergraduate audit notes before the sampling material.
- Build one template for a cycle audit and reuse it for acquisition and revenue.
- Practice sampling tables until reading an upper deviation limit is quick.
- Read the requirements of the revenue cycle task early, while you study acquisitions.
How We Help with D251

Frequently Asked Questions
A review of audit planning, sampling, data analytics, completion and reporting, then application to the acquisition and payment cycle and, in a performance assessment, the revenue cycle.
D215 is the undergraduate audit course. D251 is a graduate MACC course with more emphasis on sampling methods and full cycle audits.
A sampling method that treats each dollar as a unit, so larger items are more likely to be selected. It is commonly used to test for overstatement.
The guide uses it as the worked application before students apply the same approach to the revenue cycle.
It appears in WGU's Master of Accounting program guides, including the audit-focused version.
No. We tutor and prepare models on similar facts; the assessment must be your own work.
