ESIP practice questions - frequently asked questions

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

The ESIP exam spans 5 domains: Development (15% of the exam); Design (25% of the exam); Installation (30% of the exam); Commissioning (17% of the exam); Operations, Maintenance, and Decommissioning (13% 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: Installation 30%; Design 25%; Commissioning 17%; Development 15%; Operations, Maintenance, and Decommissioning 13%.

The ESIP exam has 70 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
