CESW practice questions - frequently asked questions

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

The CESW exam spans 4 domains: Understand Electrical Safety-Related Work Practices (20% of the exam); Establish an Electrically Safe Work Condition (20% of the exam); Identify Precautionary Techniques for Work Involving Electrical Hazards (20% of the exam); Perform an Electrical Hazard Risk Assessment (40% 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: Perform an Electrical Hazard Risk Assessment 40%; Understand Electrical Safety-Related Work Practices 20%; Establish an Electrically Safe Work Condition 20%; Identify Precautionary Techniques for Work Involving Electrical Hazards 20%.

The CESW exam has 110 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
