ExploreAbout this exam
The NRPP Radon Proficiency Program issues the Radon Measurement Field Technician (RMFT) credential, one of several certifications listed on the NRPP site under Measurement Technician Exams. NRPP describes itself as awarding radon practitioner credentials since 1998, recognized by the EPA and accredited by the ANSI National Accreditation Board under ANSI/ISO/IEC 17024, and it states that all certified individuals must conduct business in accordance with the applicable ANSI/AARST Standard(s). The credential signals mastery of the specific skills needed to complete radon testing projects, and NRPP notes that private certification is required by multiple federal and state agencies. This page is an independent study resource; it is not affiliated with, endorsed by, or operated by NRPP.
Be aware that the official RMFT credential page returned a "page can't be found" error when this page was built, so NRPP has not published an exam blueprint, item count, time limit, passing score, fee amount, or domain weighting in the material available here. Those details must be confirmed with NRPP directly, starting from the Measurement Technician Exams page linked in the site navigation or the NRPP Candidate Handbook.
What the source does confirm: NRPP certification requires biennial documentation of competence, expertise, and performance covering skill, knowledge, and quality control; a supervisory policy update effective September 1, 2025 concerns RMFTs and seven (7) business days; and NRPP exam, initial certification, and renewal fees changed effective January 1, 2025, with no amounts stated. Preparation should therefore center on the NRPP Candidate Handbook, the NRPP Candidate Study Guides, initial training courses, and the required ANSI/AARST standards. Use the FAQ below to plan study order and avoid the most common planning mistakes.
What you'll study
About NRPP RMFT preparation
What exactly does the RMFT credential cover?
NRPP frames its credentials as evidence of mastery of the specific skills required to complete radon testing and remedial projects, and requires certified individuals to work in accordance with the applicable ANSI/AARST Standard(s). The RMFT sits among NRPP's Measurement Technician Exams. The detailed task list is not published on the sources available here, so confirm scope through NRPP's Measurement Technician Exams page and Candidate Handbook.
How many questions are on the exam and how long is it?
Not stated in the available source material. The official RMFT credential page returned a not-found error, and the NRPP home page gives no item count or time limit. Treat any number you see elsewhere as unverified and confirm it with NRPP before you schedule. Plan for a proctored, knowledge-based certification exam typical of ANSI/ISO/IEC 17024 personnel programs, but do not budget your time around an unconfirmed figure.
What score do I need to pass?
No passing score is published in the source material available here. NRPP's site does not state a cut score for the RMFT exam. Ask NRPP directly, or check the NRPP Candidate Handbook, which is the document NRPP links for candidates. Avoid relying on passing scores quoted in forums, since exams and cut scores are revised over time.
How much does the exam and certification cost?
The amount is not stated. NRPP announced that effective January 1, 2025, fees for Exams, Initial Certifications, and Renewal Certifications were updated, but the notice gives no dollar figures. Check the NRPP certification portal or contact the NRPP Administrative Office for current pricing before you budget. Do not carry forward older fee figures you may have seen.
Can I retake the exam if I fail, and how soon?
The source material does not describe a retake policy, waiting period, or retake fee for the RMFT exam. NRPP's Candidate Handbook is the likeliest place for that policy, and the NRPP Administrative Office can confirm it. Because fees were revised effective January 1, 2025, verify any retake charge at the same time rather than assuming an older amount.
How long is the certification valid?
NRPP states that achieving and maintaining certification requires biennial documentation of competence, expertise, and performance to demonstrate skill, knowledge, and quality control. In practice that means a two-year cycle with renewal requirements rather than a lifetime credential. NRPP publishes a separate How to Renew Your Certification page and a First Certification Cycle To-Do List for new certificants.
What changed for RMFTs on September 1, 2025?
NRPP posted a Radon Measurement Field Technician Certification Supervisory Policy update stating that as of September 1, 2025, RMFTs will have seven (7) business days. The announcement excerpt is truncated, so the full scope of what the seven business days applies to is not visible in the available source. Read the complete notice on the NRPP site before relying on it.
What should I study first?
Start with the NRPP Candidate Handbook for administrative rules, then the NRPP Candidate Study Guides that NRPP links for candidates. Work through the required ANSI/AARST standards, since NRPP requires certified individuals to conduct business in accordance with them. NRPP also lists initial training courses and mandatory standards overview courses. Build device knowledge from the approved device list and radon measurement methods pages.
What is the most common preparation mistake?
Studying to a remembered blueprint instead of the current one. The RMFT credential page was unavailable when this page was built, fees changed effective January 1, 2025, and a supervisory policy update took effect September 1, 2025. Candidates who rely on outdated item counts, fees, or supervision rules waste effort. Verify every administrative detail with NRPP before scheduling.
