USPS 955 Exam Practice Questions 


Section 1: Maintenance Knowledge and Skills

This section assesses the candidate's technical knowledge and skills relevant to maintenance work.

It typically covers topics such as:

  • Safety Practices – Questions related to workplace safety, including personal protective equipment, safety procedures and hazard recognition.
  • Tools and Measuring Instruments – Questions on the use of various hand tools, power tools and measuring devices commonly used in maintenance tasks.

  • Basic Mechanical Concepts – Questions could cover mechanical principles such as levers, pulleys, gears, bearings and hydraulics.
  • Building Maintenance – This can include questions on plumbing, carpentry, painting and HVAC systems.
  • Troubleshooting and Repair – Questions might involve scenarios requiring the diagnosis and repair of mechanical or electrical problems.


Example Question 1. Safety Practices 

You are performing maintenance on a conveyor belt system. Before starting the work, which of the following safety procedures should you follow first?

a) Notify your supervisor that the machine will be temporarily out of service
b) Ensure that the conveyor belt's power source is disconnected and properly locked out/tagged out
c) Check the surrounding area for any unrelated safety hazards
d) Start disassembling the parts of the conveyor belt that require maintenance

The correct answer is: b) Ensure that the conveyor belt's power source is disconnected and properly locked out/tagged out.

Example Question 2. Tools and Measuring Instruments

Which tool is most appropriate for measuring the voltage present in an electrical circuit?

a) Ammeter
b) Multimeter
c) Caliper
d) Torque wrench

The correct answer is: b) Multimeter

Example Question 3. Basic Mechanical Concepts

A pump is moving 300 gallons of water every minute at a speed of 60 RPM (revolutions per minute). If the speed of the pump is reduced to 30 RPM, how many gallons of water will the pump move per minute, assuming the pump's efficiency remains constant?

a) 150 gallons
b) 300 gallons
c) 600 gallons
d) It cannot be determined from the information given

The correct answer is: a) 150 gallons

To solve this problem, we can use the direct proportionality between the speed of the pump in revolutions per minute (RPM) and the amount of water it moves in gallons per minute. Since the pump's efficiency remains constant, we can say that the volume of water moved is directly proportional to the pump's speed.

The pump moves 300 gallons of water every minute at a speed of 60 RPM. This gives us a baseline for understanding the relationship between speed and volume moved.

The speed of the pump is reduced to 30 RPM, which is half of its original speed (60 RPM → 30 RPM, or 60 RPM / 2).

Because the efficiency of the pump is constant, when you reduce the speed of the pump by half, the volume of water moved is also reduced by half. This is a direct proportion. If at 60 RPM, the pump moves 300 gallons, then at 30 RPM, it would move half of that amount, because 30 RPM is half of 60 RPM.

Half of 300 gallons is 150 gallons. Therefore, at 30 RPM, the pump moves 150 gallons of water per minute.

Example Question 4: Basic Electrical Concepts

Which of the following electrical components is used to store an electrical charge?

a) Resistor
b) Capacitor
c) Inductor
d) Transformer

The correct answer is: b) Capacitor

Example Question 5: Troubleshooting and Repair

You are troubleshooting a malfunctioning electric motor that suddenly stopped working. What should be the first step in diagnosing the problem?

a) Replace the motor immediately with a new one
b) Check if the power supply to the motor is intact and functioning
c) Dismantle the motor to inspect the internal components
d) Apply lubricant to the motor's moving parts and restart it

The correct answer is: b) Check if the power supply to the motor is intact and functioning

Example Question 6: Building Maintenance

When replacing a damaged floor tile, which of the following actions should be performed first?

a) Apply adhesive to the new tile
b) Remove the grout surrounding the damaged tile
c) Clean the surface where the new tile will be placed
d) Measure the area to ensure the new tile fits perfectly

The correct answer is: b) Remove the grout surrounding the damaged tile


Section 2: Personal Characteristics and Experience Inventory

This section evaluates the applicant's personal traits and experiences that are relevant to a maintenance career at the USPS. It might include questions about:

  • Work Experience – Questions regarding past experiences that demonstrate mechanical aptitude and problem-solving skills.
  • Personal Characteristics – Questions that assess qualities such as reliability, cooperation, and the ability to work independently or as part of a team.
  • Situational Judgment – These questions present hypothetical work-related scenarios to evaluate the candidate's judgment, decision-making and ability to interact effectively in various situations

Example Question 1: Work Experience

Describe a situation from your previous work experience where you had to solve a problem in a limited amount of time.

What was the issue, and what steps did you take to resolve it?

a) I have never encountered a situation where I had to solve a problem quickly
b) I noticed an error in a report due the next day; I stayed late, corrected the error and double-checked the rest of the report
c) I ignored the problem, hoping it would resolve itself before the deadline
d) I passed the responsibility to a coworker because I was too busy with other tasks

The correct answer is: b) I noticed an error in a report due the next day; I stayed late, corrected the error, and double-checked the rest of the report

This answer demonstrates problem-solving skills, initiative, and responsibility. The candidate identifies a problem, takes immediate action to correct it and ensures that the solution is complete and accurate, qualities that are valued in any work environment.

Example Question 2: Personal Characteristics

How would you describe your approach to work?

a) I prefer to wait for instructions before I start anything to avoid mistakes
b) I like to tackle tasks as they come, even if it means sometimes skipping breaks
c) I plan my work ahead and prioritize tasks to ensure efficiency and meet deadlines
d) I usually keep to the minimum required effort, as I believe in working smart, not hard
