NRPP Compliance: An End-of-Year Summary
In late 2024, NRPP’s Certification Council approved revisions to its compliance policy, which included:
• Clarifying the policy and process for filing complaints against NRPP-certified professionals;
• Classifying various types of infractions and associated disciplinary actions for each class;
• Creating a new policy and procedures for filing complaints against NRPP and its certification programs; and
• Defining various categories of appeals and clarifying the policy and procedures for filing an appeal.
Since the publication of the new policies, NRPP has received a steady stream of complaints against certified professionals and complaints against its own certification policies. Below please find a summary of the 2024 and 2025 complaints NRPP received about NRPP certified professionals, many of which were dismissed because the subject of the complaint was not certified or because the complainant didn’t provide enough information to substantiate the complaint and did not respond to NRPP’s request for additional information.
Types of Complaints Received
The following information includes the type of complaint filed (standards versus conduct) and the topic (issue being complained about) for all complaints received in 2024 and 2025, including the ones that were dismissed. Please note that NRPP did not take action on all of these and many did not lead to disciplinary action.

ADVERTISERS: New Year, New Opportunities!
NRPP Measurement Certifications Have Been Revalidated
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 assess 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, highlighted HERE, 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.
Changes to the initial measurement professional credential 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-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.
For more on changes for initial and renewal measurement credentials, see the blog post HERE.
