It has two timed, computer-based parts taken at a testing center: Multicraft (60 items in 60 minutes) and Spatial Relations (68 items in 40 minutes), about two hours in total. Passing score is 70, but selection is rank-based — aim for 85+.

Sample Postal Exam 955 Practice Questions

Try these sample questions to review concepts for the Postal Exam 955 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 162+ question experience with AI tutoring.

1Which truth-table output describes a 2-input AND gate?
A.Output is 1 only when both inputs are 0
B.Output is 1 only when both inputs are 1
C.Output is 1 when at least one input is 1
D.Output is 0 when both inputs are equal
Explanation: An AND gate outputs 1 only when ALL inputs are 1. With both inputs at 1, output = 1; in every other combination (0,0), (0,1), (1,0), the output is 0.
2A NAND gate's output is the equivalent of which combination?
A.An OR followed by an inverter
B.An AND followed by an inverter
C.Two inverters in parallel
D.An XOR followed by an AND
Explanation: NAND literally means 'NOT AND' — the gate performs the AND operation, then inverts the result. So output = 0 only when all inputs are 1.
3On a schematic, the symbol of a triangle pointing into a vertical line with a perpendicular bar represents which device?
A.Resistor
B.Diode
C.Capacitor
D.Inductor
Explanation: A diode is drawn as a triangle (anode) pointing toward a vertical line (cathode). Current flows in the direction of the triangle (anode to cathode) when forward-biased.
4A diode is forward-biased when:
A.The anode is more negative than the cathode
B.The cathode is more positive than the anode
C.The anode is more positive than the cathode by at least the forward-voltage drop
D.Both anode and cathode are at the same potential
Explanation: A silicon diode conducts when the anode is more positive than the cathode by roughly 0.6–0.7 V (the forward-voltage drop). Below that, the diode remains off.
5An NPN transistor is in saturation when:
A.Base-emitter junction is reverse-biased
B.Both junctions are reverse-biased
C.Both base-emitter and base-collector junctions are forward-biased
D.Collector-emitter voltage equals the supply
Explanation: An NPN transistor is in saturation when BOTH junctions are forward-biased — the device acts like a closed switch with a small V_CE (≈ 0.2 V).
6Which gate outputs 1 when the inputs are different and 0 when they are the same?
A.AND
B.OR
C.XOR
D.NOR
Explanation: XOR (exclusive-OR) outputs 1 when inputs differ and 0 when they match. It's the workhorse for binary addition (sum bit) and parity checking.
7An ideal op-amp has which of these characteristics?
A.Zero input impedance and infinite output impedance
B.Infinite open-loop gain, infinite input impedance, zero output impedance
C.Unity gain and 50-ohm input impedance
D.Negative input impedance
Explanation: An ideal op-amp has infinite open-loop gain, infinite input impedance (no input current), and zero output impedance. Real op-amps approach these as design targets.
8A schematic shows a component with a coiled symbol crossed by an arrow. What is it?
A.Fixed resistor
B.Variable inductor
C.Capacitor
D.Photodiode
Explanation: A coil with an arrow through it is a variable inductor — the arrow indicates the value can be adjusted (e.g., a tuning coil).
9Which logic gate is functionally complete by itself (any logic circuit can be built from it alone)?
A.AND
B.OR
C.NAND
D.XOR
Explanation: NAND (and NOR) are universal gates — any Boolean function can be built using only NAND gates. AND, OR, and XOR are not functionally complete by themselves.
10A zener diode is normally operated in:
A.Forward bias above 0.7 V
B.Reverse breakdown region
C.Saturation region
D.Open-circuit mode
Explanation: A zener diode is designed to operate in its reverse breakdown region, where its voltage remains nearly constant at the zener voltage — useful for voltage regulation.

About the Postal Exam 955 Exam

The USPS Postal Exam 955 is the Maintenance Selection System exam used to hire Electronic Technician, Building Equipment Mechanic (BEM), Mail Processing Equipment (MPE) Mechanic, Maintenance Mechanic, and Area Maintenance Technician. It is a computer-based test taken at a testing center in two timed parts: Multicraft (60 items in 60 minutes), which covers mechanical and electrical job knowledge, and Spatial Relations (68 items in 40 minutes).

Exam sponsor: United States Postal Service (USPS). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Postal Exam 955: Suggested Study Strategy

1Master Ohm's Law in three forms (V=IR, I=V/R, R=V/I) — multiple multicraft items use it as the underlying step.
2Drill logic-gate truth tables (AND, OR, NAND, NOR, XOR) until you can write them from memory in under a minute.
3Practice both spatial item types — fitting flat pieces together without gaps, and matching top, front and right views to a solid — 15 minutes a day.
4Know the six-step LOTO sequence and NFPA 70E arc-flash boundary categories — safety items repeat across versions.
5Answer every item: there is no penalty for guessing on either part, and you cannot return to a part once its timer ends.

Frequently Asked Questions

What is the passing score on USPS Postal Exam 955?

USPS sets a minimum passing score of 70 on the 955, not counting Veterans' Preference points, but selection is rank-based — higher-scoring candidates are contacted first. Competitive scores are typically 85 or higher. Your result is valid through the expiration date shown on your Notice of Result.

How is the USPS 955 structured?

The 955 has two timed parts taken on a computer at a testing center: Multicraft (60 items in 60 minutes) and Spatial Relations (68 items in 40 minutes). The whole assessment takes about two hours, and once a timed part ends you cannot return to it.

Which USPS jobs use the 955 exam?

USPS uses the 955 to hire Electronic Technician, Building Equipment Mechanic (BEM), Mail Processing Equipment (MPE) Mechanic, Maintenance Mechanic, and Area Maintenance Technician. All five crafts take the same 955 multicraft battery but apply for different vacancy announcements.

Is the USPS 955 exam free?

Yes. USPS never charges a fee for exams, applications, or employment information. Report anyone who asks you to pay for the 955 to the U.S. Postal Inspection Service or the FTC.

What topics are on the 60-question multicraft test?

USPS describes the 60-item Multicraft part as a test of knowledge and skill in the mechanical and electrical areas, with no penalty for guessing. It does not publish a topic list or topic weights.

Can the 955 be taken remotely?

No. The 955 is taken at a testing center, where the computer administers and times the test and a proctor monitors the session. There is no take-home part.

Can I retake the USPS 955?

You cannot retest for the same job posting. You can retest for other postings that require the 955 if you apply on or after your Retest Eligibility Date, which eCareer shows under Assessments.
