Postal USPS Virtual Entry Assessment License: Complete Roadmap
Follow this path to maximize your chances of passing on the first try
Audit your craft baseline (electronics, electrical, mechanical, HVAC, computers)You are here
Sketch what you already know vs. what you need to study. Electronic Technician and MPE Mechanic candidates lean electronics/electrical; BEM leans HVAC; Maintenance Mechanic leans mechanical. The 60-Q multicraft block covers all of it.
Drill core multicraft topics with worked problems
Ohm's Law, series vs parallel, logic-gate truth tables, gear ratios, refrigerant cycle, and IP basics. The proctored block is short — accuracy matters more than speed.
Practice spatial reasoning daily (rotation + paper folding)
PSI's spatial items reward repetition. Time yourself on rotation, paper-folding, and assembly puzzles for 15 minutes a day until you can answer without backtracking.
Complete the Personal Characteristics & Experience Inventory honestly
Part 1 (~120 items, ~75 min) is take-at-home but timed once started. Answers cross-check your application — be consistent, choose strong-but-credible responses, and finish in one sitting.
Review safety: LOTO, NFPA 70E, PPE, SDS, OSHA general industry
Eight or so safety items show up. Know the LOTO six-step sequence, NFPA 70E arc-flash boundaries, and the four sections of an SDS most often referenced (hazards, first aid, handling, PPE).
