NRPP Exams

NRPP Exam Requirements, Fees and Registration

* For NJ Licensing Exams see New Jersey DEP Radon Licensure Program.

All NRPP exams are now proctored remotely online through’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.

Step 3:

Once you pay for your exam, you will receive an email from Examity with login information to set up your profile and schedule your exam. Please check your spam folder if you do not see the email. If you do not pass your exam the first time, you will be required to pay the exam fee again to retake the exam (please wait until you receive your official exam results via email before rescheduling). 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.
