Nine key controls, each given a population, a method and a sample size from one stated table, make up AC557's Unit 5 test plan for a composite scrap recycler. Searches like "ac 557 unit 5 assignment example", "ac557 unit 5 sample" and "ac557 unit 5 example" land here.
What a finished AC557 Unit 5 test plan looks like
Six pages built on one table, with a sample-size key above it. The key ties size to frequency and risk: one for an automated control once general controls are relied on, two or five for monthly controls, 25 or 40 for daily ones, the higher figure wherever fraud risk is rated elevated. Each of the nine key controls then gets a row: attribute tested, population and its source, the period covered, method, sample size, selection approach and what counts as a deviation. The daily override review draws 40 of 912 yard-days, split 14, 13 and 13 across the three yards. All 84 monthly scale checks are inspected because the log is short. A final section explains the rollforward from September to December 31.
How a AC557 Unit 5 example is structured
Every row is fixed before testing begins, and the plan makes that visible by listing deviation definitions ahead of any results column, since a deviation defined afterward can be defined away. Populations are named with their source and a completeness step: the 912 yard-days come from the scale system's operating calendar, agreed to attendance records for yard controllers. The automated price-table control is tested once per grade family only because change management over the scale software was tested separately and found effective, and the plan states that dependency. The kiosk loading control is excluded from operating tests because the walkthrough found its design deficient, and testing a control that cannot work as designed yields nothing useful. Tolerable deviations are zero at the planned size. Seller identification is noted as a compliance control and tested outside the plan.
A size key tied to frequency
Automated controls one each, monthly two or five, daily 25 or 40, the larger figure where the worksheet flagged fraud. Every size in the table traces back to this key.
Deviations defined before results
For the override review, a missed sign-off, a sign-off after ten the next morning, or an override above 150 dollars closed without a documented reason each counts.
Populations with a source
912 yard-days from the scale system's calendar, agreed to controllers' attendance; 84 monthly scale checks from the maintenance log; the override report itself tested for completeness.
A control left untested, on purpose
The kiosk loading control is excluded because its design already failed the walkthrough, and the plan records why operating tests would add nothing.
Interim to year-end
Testing covers January to September; October through December is rolled forward with inquiry, inspection of any changes and five further override review selections.
Where marks go in AC557 Unit 5
A sample size with no stated basis is the first thing graders question, since the plan exists to show where each number came from. Populations defined loosely, all tickets or the year's reviews, without a source or a completeness step leave the sample unanchored. Deviations defined after results, or never defined, suggest findings could be argued away. Testing an automated control with a large manual sample wastes effort and signals a misunderstanding; relying on a test of one without addressing change management is the opposite error. Testing a control already known to be poorly designed draws comment from most graders. Plans that stop at September, with no rollforward to the assessment date, leave the conclusion uncovered for a quarter, and graders notice that gap.

AC557 Unit 5 questions, answered
Why is an automated control tested only once?
An automated control performs the same way every time unless its programming changes. If change management over the system is effective, one test per configuration shows how it behaves across the period. The plan tests the price table once per grade family and states that the conclusion depends on the separate change management testing, the condition graders look for.
Where do sample sizes like 25 or 40 come from?
From guidance that scales size to how often a control runs and how much reliance rests on it. Firms and companies publish their own tables, and many courses supply one. The plan states its key at the top and applies it consistently, so if your section gives a different table, the sizes change while the logic stays the same.
Why not test a control that failed the walkthrough?
Because the walkthrough already showed the design cannot achieve its objective, so operating tests would only confirm that a flawed control ran as flawed. The deficiency is evaluated from the design finding directly, and testing resumes once the control is redesigned, which the remediation unit schedules with a date.
