National Radon Proficiency Program (NRPP) examinations are offered online with NRPP only. These exams are challenging, and the successful completion of a KSU course will significantly improve your ability to pass the examination. 

To be listed or licensed by states, you need to pass a national proficiency exam. NRPP is administered by the American Association of Radon Scientists and Technologists (AARST). Check with the states in which you wish to do business  to see whether there are additional requirements.

If you are seeking advanced NRPP certification in multifamily or school and large building measurement or mitigation, you need to be NRPP certified in measurement or mitigation. NRPP does not view state licensing as a substitute for NRPP certification.
