For all other states, please check with your state’s radon program to determine their exam and licensing requirements.

All NRPP exams are now proctored remotely online through Examity.com’s live proctoring platform. Exam candidates will present their Government-issued photo ID, answer a security question and complete a biometric keystroke match. The Proctor will explain exam rules and instruct test-takers to perform a 360-degree room scan to confirm the workspace is free of any unauthorized materials. Exam sessions are recorded from start to finish and any suspicious behavior will be flagged. Once completed, the exam recording is audited for quality control before releasing the audio, video, and analytics to the NRPP for recordkeeping. Once audited, test-takers will receive their exam results via email within 48-72 business hours. You may purchase exam study guides here: Student Study Guides. If you need to retake an exam or schedule an additional exam, you will need to return to this website to purchase another exam prior to scheduling with Examity.

Step 1:

Please check the boxes below to register for an exam. We also recommend running a computer check (click here) prior to paying for your exam. Exams should be scheduled no later than 6 months from purchase date.

I understand that I can NOT use my iPad or iPhone to take the exam.
I have a computer with Microsoft Windows or Apple operating system.
I have Chrome or Firefox installed as my browser.
I have a built-in (or external) webcam and microphone.
I have an Internet connection with a minimum speed of at least 2 Mbps download and 2 Mbps upload.
I agree that if I show up to the exam without meeting these requirements I will be charged an additional rescheduling fee.
*Note: If you cancel your exam within 24 hours of your scheduled exam time, for any reason, you will be required to purchase another exam before you can reschedule.

You may not take an exam more than four times in a 12-month period. Once you pass an exam, you may not take it again unless your certification has been expired for two years.
