USPS 955 Exam Prep Course
Updated: September, 2026
The USPS maintenance hiring process starts with one critical hurdle: Exam 955. This two-part screening combines a Personal Characteristics and Experience Inventory (an unproctored personality and work-style questionnaire) with a proctored Technical Test (Multicraft and Spatial Relations) to determine which candidates move forward to the next stage of the USPS hiring process - the interview.
Key facts about the USPS 955 Exam:
- You'll receive a specific deadline by email after your invitation, and missing it results in an automatic "Ineligible" status, so it's best to start practicing before the invitation arrives
- Failing results in a mandatory 6-month cooldown before you're allowed to retest
- The same exam qualifies you for multiple maintenance roles: Maintenance Mechanic, Building Equipment Mechanic, Area Maintenance Technician, Mail Processing Equipment Mechanic, and Electronic Technician
*Your Exam 955 score is stored in your eCareer Candidate Profile and stays valid for future maintenance applications requiring the same exam, so a strong score keeps paying off well beyond your current application.

Inside the Prep Course - Preview
We've created a comprehensive USPS 955 Exam Prep Pack designed to help you succeed. Our practice tests closely mirror the actual exam's format and timing, allowing you to identify and improve your weaker areas across both the Multicraft and Spatial Relations sections. With this focused preparation, you'll be confident and ready to perform on test day.
Why preparation matters: Exam 955 covers an unusually wide range of technical subjects, electrical theory, mechanics, hydraulics, motors and controls, all within a strict 60-minute limit per section, with no calculator and no second attempt if you score below 70. Our practice tests are deliberately harder than the real exam, so when test day comes, you'll find the actual questions manageable.
What’s Inside Our USPS 955 Exam Prep Pack
Using our USPS Exam 955 PrepPack, you get:
- 21 topic-specific practice tests across all Multicraft content areas - 3 Mechanics tests covering power transmission, hydraulics, pneumatics, and piping; 9 Electronics tests covering AC/DC theory, parallel circuits, motors, PLCs, control circuits, test instruments, and digital electronics; and 6 Workshop & General Maintenance tests covering welding, rigging, tools, and safety procedures - so every topic area is covered before test day.
- 3 Spatial Relations practice tests targeting both question types on the exam - Matching Parts & Figures, Matching Shapes, and 3D Object visualization - the section candidates consistently find most time-pressured and hardest to improve without dedicated practice.
- 2 timed full simulations replicating actual exam conditions - a Multicraft Simulation (60 questions, 60 minutes) and a Full-Length Exam Simulation (125 questions) covering both parts of the exam under the same time constraints you will face on test day.
- 7 in-depth study guides covering every technical domain - dedicated guides for Mechanical & Electrical, Electrical General, Hydraulics, Pneumatics, Power Transmission, Welding, and Rigging - building the theoretical foundation the 955 exam tests beyond what practice questions alone can provide.
- Complete answer explanations for every question - not just correct/incorrect, but the reasoning and formulas behind each answer, so you understand why the right answer is right and can apply the same logic to questions you haven't seen before.
- A proven prep system built on 30+ years of experience - developed by assessment specialists who have analyzed the Ramsay Multicraft format and USPS's specific implementation of Exam 955, and refined based on feedback from thousands of candidates who have gone through the actual hiring process.
Free Sample Questions
This question tests your understanding of how a conductor's physical dimensions affect its resistance. You're given a resistor's original resistance and asked to find the new resistance after only its cross-sectional radius changes, everything else about the material and length stays the same.
A resistor of length L, radius of cross- section r and resistance of 20Ω are represented below. What will be the resistance of a new resistor of 2r radius?
The correct answer is C.
We can consider the enlargement of the cross section (radius) of the resistor as though another resistor was connected in parallel:
We will calculate the new value of the resistor according to the sum of resistors in parallel:
Firstly, we will calculate the number of resistors in parallel using the cross- section of the original resistor (as given): 
We will calculate the cross- section of the new resistor: 
We can see that the cross- section of the new resistor is 4 times the original cross- section, meaning we need to calculate as though we have 4 resistors connected in parallel:
This question tests your ability to mentally combine several separate flat shapes into a single polygon. You need to determine which answer option represents all the given pieces fitting together edge to edge, with no gaps and no overlapping area.
Choose the polygon that combines the following shapes (A-H), without gaps or overlap:
The correct answer is the pentagon.
Start by adding up the total area and angle count across all the given pieces (A-H), rather than trying to visually assemble them from scratch. That total has to match whichever answer option is correct, which immediately rules out shapes that are clearly too small or too large for the combined area.
Next, check the angles. When pieces meet edge to edge, the angles at each shared point need to add up to a value that makes geometric sense, 180 degrees along a straight edge, 360 at a fully enclosed point. The triangle and diamond options can be eliminated this way: they don't provide enough total angle at their vertices to accommodate all the given pieces meeting at shared points. The rectangle and trapezoid require every internal angle to be exactly 90 degrees, but at least one of the given pieces has an angle that isn't a right angle, which rules both of them out too.
That leaves the pentagon as the only shape whose combined area and angles are consistent with all the pieces provided.

USPS 955 Exam FAQs
The most effective preparation combines full-length timed practice with targeted review of your weak areas. Work through complete practice tests under the same time limits you'll face on exam day, 60 minutes for Multicraft, 60 minutes for Spatial Relations, so the pacing feels familiar rather than foreign. Our USPS 955 Exam Prep Pack is built around this approach: full-length simulations, section-by-section practice tests, and in-depth study guides for every topic the exam covers, so you can identify and strengthen specific weak spots rather than re-studying everything evenly.
Most candidates see the best results starting 2-3 weeks before their scheduled test date, enough time to work through practice material across both sections, revisit weak areas at least once, and take a final full-length simulation close to test day without cramming. If your invitation gives you a shorter window, prioritize timed practice under real exam conditions over passive review, it builds the pacing and stamina you'll actually need on test day.
Yes. Both sections are part of the same proctored Technical Test appointment, and both count toward your overall score, there's no option to test on just one regardless of which maintenance role you're applying for. Even candidates with strong hands-on mechanical experience are often caught off guard by the Spatial Relations section's time pressure, and candidates confident in visual reasoning can still struggle with the breadth of electrical and mechanical topics on the Multicraft section. Preparing for both is the safer path to a passing score.
Both come with real gaps that can hurt you on test day. A free study guide PDF is static, it can outline topics, but it can't simulate the timed, high-pressure format of the actual exam, and it won't tell you which specific areas you're weak in. AI-generated practice questions have a different problem: general AI tools have no access to USPS's official exam format or item bank, so they can only guess at question style and difficulty, and they can produce technically plausible-sounding explanations that are simply wrong, particularly on circuit calculations, formulas, or ladder logic. On a technical exam like this, a confidently wrong AI-generated explanation can do more harm than no practice at all.
Our USPS 955 Exam Prep Pack solves both problems: timed practice tests that mirror the real exam's format and pressure, paired with explanations verified against real technical references, not generated on the fly.
