USPS Postal Exam 477 cheat sheet

Safety overrides speed: if a task cannot be completed both quickly and safely, the safe method governs and the hazard is reported before work resumes.

Written procedure outranks a co-worker's verbal shortcut; follow the written instruction and tell the supervisor that a shortcut was suggested.

Escalation rule: a problem beyond your authority (equipment fault, damaged mail, irate customer request) goes to the supervisor, not to a peer's guess.

Customer and mail data - names, addresses, contents, account details - are shared only with authorized employees and the addressee.

Detection rule: an error found at your station is corrected at your station; forwarding a known mis-sort pushes the defect downstream.

Priority rule: mail-handling and customer-commitment deadlines outrank non-urgent side tasks; only a supervisor can re-rank them.

Peer conflict: raise a co-worker's performance issue privately and specifically first; escalate when it repeats or affects safety or service.

Attendance rule: notify using the local call-in procedure before shift start; a notified absence and a no-call absence are handled differently.

Integrity rule: a shortcut that misrepresents work as completed is refused even when it is faster and no one would notice.

Format: a self-report inventory asking how often you performed specific work behaviors in past jobs, answered on a frequency scale.

Scoring rule: no single response is 'correct'; the overall pattern is compared against profiles of successful postal employees.

Consistency rule: similar statements are repeated in different wording, and contradictory answers signal inaccurate self-reporting.

Overclaiming rule: endorsing every favorable statement - never late, never an error, always praised - yields an implausible profile.

Anchor rule: answer from how often the behavior actually occurred at your most recent job, not from how you intend to behave.

Coverage areas: attendance, safety compliance, rule-following, teamwork, customer contact, response to supervision, and response to criticism.

Recall rule: before answering a block, retrieve one concrete incident per behavior area to stabilize your frequency judgment.

Pace rule: statements are short but must be read in full; misreading produces responses that conflict with later similar items.

Task rule: compare a master entry to a comparison entry and mark any difference in any character, including spacing and punctuation.

Scan rule: compare field by field - number, street name, suffix, secondary unit, ZIP - rather than judging the whole line at a glance.

Digit rule: a transposition (14 vs 41) is a mismatch even though both digits are present; position matters, not digit inventory.

Look-alike set: O/0, I/1, S/5, B/8, Z/2 are the usual substitutions; compare character shapes deliberately.

Field rule: a dropped directional (N, S, E, W) or a missing Apt/Ste/Unit changes the address and counts as an error.

Coding rule: apply the printed conversion key exactly; a substituted 'close' code counts as wrong even if it seems logical.

Budget formula: per-item target = total items ÷ total minutes; abandon and guess on any item running about twice the target.

Guessing rule: where no wrong-answer penalty is stated, mark your best judgment rather than leaving the item blank.

Verification rule: after flagging a difference, recheck that pair once; a false positive and a missed error usually cost the same.
