THE RADON REPORTER | 9 PROFICIENCY Mitigation Certification Updates Results of NRPP Radon Mitigation Certification Revalidation NRPP notified readers in the last issue of Radon Reporter of the outcome of NRPP’s measurement certification revalidation process and changes to the Radon Measurement Professional and Field Technician certification programs. This article updates readers on the changes to the Radon Mitigation Specialist and Mitigation Installer certification programs as a result of the revalidation of these programs, which were approved by NRPP’s Certification Council in February. The revalidation process involved regular meetings of committees of subject matter experts to review the content and format of NRPP’s certification examinations, the requirements for initial certification, the recertification interval, and the recertification activities. The process included a validation survey, which many industry members completed. Survey results were used to guide the development of the 2025-2026 programs. Because NRPP’s certifications are designed to identify individuals who possess the knowledge and skills necessary to protect the public from the harmful effects of radon, NRPP revalidates its certification programs at regular intervals to align certification requirements with essential, job-related competencies. Although a solid deadline for rolling out these changes has not yet been set, NRPP is aiming for mid-2026. Changes to the Radon Mitigation Installer Certification The Mitigation Installer credential is designed to identify individuals who are proficient at installing soil depressurization systems following designs provided by the certified system designer. This can include installing pipes, fans, and other equipment necessary to reduce contaminants to below their respective action levels. They understand the necessary practical considerations for a successful installation, and they notify the supervising Mitigation Specialist when encountering problems. Mitigation Installers follow safety protocols established by the Mitigation Specialist to protect themselves and the occupants of the building during the installation process and may explain the functioning of the mitigation system to the homeowner or building manager, including how to operate and maintain it. Mitigation Installers work under Radon Mitigation Specialists (and in the future, Vapor Intrusion Mitigation Specialists), installing mitigation systems in single family residential as well as commercial or other large buildings. For initial certification under the revalidated program, MIs will complete an 8-hour training course, pass a 40- item examination, report to NRPP the name of the Radon Mitigation Specialist (RMS) who will be supervising their work, and agree to the NRPP Code of Ethics/Certification Terms Agreement . MIs will recertify every two years by completing eight hours of NRPP-approved continuing education. Of these eight hours, a four-hour review course covering the SGM standard is required. The remaining four hours of continuing education may be earned from category I or category II activities. MIs will also renew their agreement to the NRPP Code of Ethics/Certification Terms Agreement and again notify NRPP of the name of their current supervising RMS. Differences between the current RMI and the new MI certification include the following: The name of the Radon Mitigation Installer certification has changed to Mitigation Installer .
