ETT practice questions - frequently asked questions

Plain answers about how ETT 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 ETT exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The ETT exam spans 4 domains: Safety (15% of the exam); Electrical Testing Fundamentals and Theory (25% of the exam); Component Testing (55% of the exam); Systems and Commissioning (5% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Component Testing 55%; Electrical Testing Fundamentals and Theory 25%; Safety 15%; Systems and Commissioning 5%.

The ETT exam has 100 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
