CHP practice questions - frequently asked questions

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

The CHP exam spans 5 domains: Measurements and Instrumentation (25% of the exam); Standards and Requirements (20% of the exam); Hazards Analysis and Controls (20% of the exam); Operations and Procedures (20% of the exam); Fundamentals and Education (15% 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: Measurements and Instrumentation 25%; Standards and Requirements 20%; Hazards Analysis and Controls 20%; Operations and Procedures 20%; Fundamentals and Education 15%.

The CHP exam has 150 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
