Sample Exam Questions

Try these 12 original PLP sample questions. They are not official National Payroll Institute questions and do not reproduce a live exam.

Question 1

Topic: Payroll governance

A payroll leader is asked to approve a new bonus process with no documented approval step. What is the best response?

• A. Add a clear authorization and audit trail before payroll release
• B. Approve it because bonuses are discretionary
• C. Let employees self-report bonus amounts
• D. Process the payments first and decide controls later

Best answer: A

Explanation: Payroll leadership should protect accuracy and accountability. A bonus process needs authorization, documentation, and review before payments are released.

Question 2

Topic: Stakeholder communication

Finance wants payroll accrual data earlier, but HR is concerned about incomplete employee-change data. What should the payroll leader do?

• A. Ignore HR and send whatever finance requests
• B. Refuse all finance reporting
• C. Ask employees to estimate accruals
• D. Define timing, assumptions, data owners, and correction procedures with both teams

Best answer: D

Explanation: Payroll leaders often mediate between functions. A good process states what data is available, who owns it, when it is delivered, and how corrections are handled.

Question 3

Topic: Legislative change

A province announces an employment-standards change affecting vacation accrual. What should payroll leadership prioritize?

• A. Wait until employees complain
• B. Review the change, update policy and system settings, test calculations, and communicate impacts
• C. Apply the change only to new employees
• D. Stop tracking vacation accruals

Best answer: B

Explanation: Payroll leadership requires change control. Legislative changes should be translated into policy, configuration, testing, communication, and review steps.

Question 4

Topic: Vendor oversight

An outsourced payroll provider processes payroll, but internal HR approves employee changes. What remains the employer’s responsibility?

• A. No responsibility remains after outsourcing
• B. Only choosing the provider’s logo
• C. Oversight of data quality, approvals, controls, service performance, and compliance obligations
• D. Letting the vendor decide all employment terms

Best answer: C

Explanation: Outsourcing does not remove accountability. Payroll leadership must oversee vendor controls, data handoffs, reports, service levels, and compliance outcomes.

Question 5

Topic: Payroll metrics

Which metric best supports payroll process improvement?

• A. Error rate by error type, pay group, and root cause
• B. Number of emails sent by payroll
• C. Number of employees with the same first name
• D. Office seating location

Best answer: A

Explanation: Useful payroll metrics connect errors to causes and process points. That lets leaders target fixes instead of only counting activity.

Question 6

Topic: Privacy

A manager asks payroll to send a full payroll register to a shared team inbox. What should the payroll leader do?

• A. Send the report because managers are senior
• B. Post the report on the intranet
• C. Remove names but leave all other sensitive fields
• D. Share only information required for a legitimate purpose through an approved secure channel

Best answer: D

Explanation: Payroll data is sensitive. Access should be limited to legitimate business needs and shared through secure, approved channels.

Question 7

Topic: Year-end readiness

What is the strongest year-end readiness practice?

• A. Start year-end only after the first employee asks for a slip
• B. File quickly without review
• C. Reconcile taxable benefits, remittances, payroll registers, and employee master data before filing
• D. Delete prior payroll reports to avoid confusion

Best answer: C

Explanation: Year-end readiness depends on reconciliation. Payroll should compare payroll data, remittances, benefits, and master records before filing.

Question 8

Topic: Escalation

A payroll analyst finds a recurring overpayment caused by a system configuration error. What should the payroll leader do?

• A. Treat it as one employee’s issue only
• B. Correct the employee, assess population impact, fix the configuration, and document the control gap
• C. Ignore prior periods
• D. Stop using payroll controls

Best answer: B

Explanation: A recurring configuration error may affect more than one employee. Payroll leadership should fix the root cause, quantify impact, and document corrective action.

Question 9

Topic: Process change

Payroll plans to automate a manual earnings upload. What should happen before the automation goes live?

• A. Remove approvals because automation is always correct
• B. Let the system run for a year before review
• C. Keep the process undocumented
• D. Test calculations, exception handling, access, approvals, and reconciliation

Best answer: D

Explanation: Automation changes risk; it does not remove risk. Testing should cover data flow, calculations, exceptions, access, approvals, and reconciliation.

Question 10

Topic: Leadership judgment

A senior executive asks payroll to delay a statutory remittance to improve short-term cash flow. What is the best response?

• A. Explain the compliance risk and escalate through proper governance if pressure continues
• B. Delay because the request is senior
• C. Ask employees to fund the remittance
• D. Hide the remittance in another account

Best answer: A

Explanation: Payroll leaders must protect compliance obligations even when business pressure exists. The answer is documented escalation, not unauthorized delay.

Question 11

Topic: Service management

Employees report slow payroll issue resolution, but the team has no case categories or response targets. What is the best improvement?

• A. Tell employees to stop asking questions
• B. Handle only the easiest cases
• C. Create intake categories, priority rules, ownership, response targets, and trend reporting
• D. Delete old cases without review

Best answer: C

Explanation: Payroll service improves when issues are categorized and measured. This supports accountability, trend analysis, training, and process fixes.

Question 12

Topic: Cross-functional change

HR changes job codes that drive overtime eligibility, but payroll is not informed until after payroll closes. What should the payroll leader implement?

• A. A rule that job codes never matter
• B. A change-control process linking HR master-data changes to payroll impact review
• C. A manual correction only if an employee complains
• D. A policy that payroll never reviews HR data

Best answer: B

Explanation: Payroll relies on accurate upstream data. Cross-functional change control reduces errors when HR, time, finance, and payroll systems interact.
