ESD practice questions - frequently asked questions

Plain answers about how ESD Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real ESD exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The ESD exam spans 8 domains: ESD training for harsh environments; Utilization of ANSI/ESD S20.20, NASA 8739.6, and Mil-Std ESD updates; Verification of ESD materials, products, and workstations; New ESD packaging, handling, storage, and transportation; Instrument-driven hands on ESD troubleshooting; Following an ESD material qualification list (MQL); Incoming inspection “first line of defense” techniques; Certification examination. Every practice question on this site is tagged to one of these domains.

The ESD exam has 50 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
