Some states have additional regulations and requirements. See a list of course approvals and regulated states here.
Entry Level - Certification Courses:
Measurement Entry Level Course - Approved by NRPP and NRSB - This course prepares you to conduct radon measurements and is the only course required to obtain certification in Measurement. It is also a pre-requisite to taking the mitigation course:
Mitigation Entry Level Course - This course prepares you to install radon mitigation systems to reduce the levels of radon in a building. The Measurement Course is a pre-requisite to this course. Please note, that although you are required to take both Measurement and Mitigation courses to become certified in Mitigation, you are not required to obtain both certifications, but your are eligible to do so if you prefer. Each certification requires its own exam and application. You can register for both courses at a discounted price:
If you have already completed an approved Measurement Course, you can register for the Mitigation Course only - If you have not already taken an approved entry level measurement course, you can register for both C-101 and C-102 at a discount (at checkout - enter the coupon code "Bundle" to receive $105 discount):
National Radon Proficiency Program (NRPP/AARST)
-Register with NRPP for exam, then schedule the exam through Examity- You will be able to take the exam from your location with a virtual proctor - this is how it works
National Radon Safety Board (NRSB)
-Schedule the exam directly through NRSB - this will be a paper and pencil exam which is given through a proctor
-Certification Exams are available in two formats. For most of the U.S. (if a facility is close to you), the exams are available through a computer-based testing facility - PSI Testing Centers. For Canada and areas in the U.S. that are not close to a PSI facility, exams are available directly through NRPP with the services of a Proctor.
Once you have successfully completed the online course and the certification exams, you will need to download the application and submit them to the appropriate certifying board.
