National Radon Proficiency Program
The NRPP provides certification credentials for professional radon testers and mitigators. As an independent administrative program of the American Association of Radon Scientists and Technologists, Inc. (AARST), the NRPP is governed by a Certification Council consisting of radon industry stakeholders who are responsible for credentialing policies and procedures.
Recognized and demanded by both federal agencies and state radon programs,
NRPP credentials indicate to building owners and service providers the mastery of
the specific skills required to successfully complete radon testing and remedial projects.
Achieving and maintaining NRPP certification requires biennial documentation of competence,
expertise and performance to demonstrate skill, knowledge and quality control.
