Over the past year NRPP has been revalidating its measurement and mitigation certification programs. Revalidation occurs at regular intervals to ensure that NRPP’s certifications assesses candidates against essential, job-related competencies. It is also a key element of ISO/IEC 17024 accreditation.
The revalidation process involved regular meetings of committees of subject matter experts to review the content and format of NRPP’s certification examinations and all requirements for initial certification and recertification. The process included a validation survey, which many industry members completed. Survey results were used to guide the development of the 2025 programs.
NRPP’s Certification Council voted in November to approve the 2025 measurement programs (RMFT & RMP). The changes are highlighted below and reflect changes in the measurement profession and requirements for safe and effective practice. The Certification Council will be reviewing the 2025 mitigation certification programs during its next scheduled meeting. Although a solid date of implementation has not yet been set, NRPP is aiming to implement the changes to both the measurement and mitigation certification programs by mid-2026.
Radon Measurement Field Technician Certification
Radon Measurement Field Technicians are responsible for deploying and retrieving approved radon measurement devices and ensuring proper device placement, which involves identifying appropriate locations for placement and/or placing devices at specified locations within a building. They document adherence to protocols including locations of device placement, closed building conditions, and statement of noninterference and other observations, and they address any issues with the device during the testing setup, such as replacing faulty devices. They also interact with building occupants as related to proper radon testing procedures, and work under the general supervision and QA/QC oversight of a Certified Radon Measurement Professional.

Changes to initial RMFT certification include:
- Training has been reduced from 12 hours to 8, focusing only on the responsibilities of the RMFT. The course must be completed before registering for the examination.
- The examination has been reduced from 85 scored questions to 60 and focuses on activities the RMFT performs before the test and during device placement and retrieval. A new section on chain of custody has been added.
- RMFTs will need to complete a two-hour device specific training course on the standard or analytical device(s) they will be using (as authorized by their supervising RMP).
- Courses will provide instruction on topics such as how to properly store and handle the device, how to initiate and stop the test, how to tell when the device has malfunctioned, and how to identify interference.
- Although device-specific training will be required whenever use of a new device type is initiated, no additional device requirements or further training will be needed for recertification.

Changes to RMFT recertification include:
- RMFTs will be eligible for category II continuing education for recertification, which includes professional activities such as attending radon-related conferences, meetings or events, delivering radon-related presentations, and authoring radon-related articles.
- RMFTs must agree to the NRPP Code of Ethics/Certification Terms Agreement
- RMFTs must update their supervisor or confirm the RMP they reported for initial certification is still their supervisor.
Radon Measurement Professional Certification
Radon Measurement Professionals deploy and retrieve, or supervise the deployment and retrieval of, radon measurement devices. They follow specific protocols and standards to ensure that the measurements are accurate and reliable. They analyze and interpret test results to determine the radon concentration in the tested area, prepare and present detailed reports on radon levels and provide recommendations. They maintain QA/QC plans and documents, ensure that equipment is properly calibrated and functioning, and provide general supervision and QA/QC oversight to Radon Measurement Field Technicians.

Changes to initial RMP certification include:
- The number of hours of training remains 16 hours, but now the course must be completed before registering for the examination.
- The examination has been reduced from a two-part, 150 scored question exam to a single, 94 item exam. There will be greater emphasis on QA and a new section on chain of custody has been added.
- In addition to submitting a DPT and calibration certificate when registering a device, RMPs will complete a two-hour device specific training course on the standard or analytical device(s) they will be using.
- Courses will provide instruction on topics such as the process for properly storing and handling the device, initiating and stopping the test, identifying interference, and interpreting data, including unique results.
- Calibration certificates will be provided annually
- Although the above will be required for initial certification and whenever use of a new device type is initiated, no additional DPTs or device specific training will be needed for recertification.
