RMI practice questions - frequently asked questions

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

The RMI exam spans 6 domains: Communicate with the Client (14% of the exam); Identify Radon Entry Points (17% of the exam); Maintain Jobsite Safety (15% of the exam); Implement Mitigation Installation Strategy (30% of the exam); Perform Post-Installation Tasks (17% of the exam); Operate in an Ethical and Professional Manner (7% 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: Implement Mitigation Installation Strategy 30%; Identify Radon Entry Points 17%; Perform Post-Installation Tasks 17%; Maintain Jobsite Safety 15%; Communicate with the Client 14%; Operate in an Ethical and Professional Manner 7%.

The RMI exam has 95 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
