This topic is also important to Mitigators, so I am also posting it here. This is from the NRPP website.

NRPP Exam Security Update: Last Update: July 17, 2023
NRPP was recently made aware of a breach in the security of the RMP (Radon Measurement Professional) and RMFT (Radon Measurement Field Technician) exams. It has been brought to our attention that a training instructor improperly obtained and shared the contents of the measurement exams.
The security of NRPP examinations is an essential component of the program’s integrity and notably its ability to ensure impartiality and fairness in the determination of candidates’ eligibility for certification. NRPP has taken swift and immediate action to prevent use of the stolen test by immediately stopping offering the RMP and RMFT exams. Testing for measurement certifications will remain suspended until new exam materials can be developed to replace those that were breached. Persons already in the certification or exam process affected by a NRPP deadline will be provided with a grace period if warranted.
We realize the impact on the industry, and especially its newest members, is great and far-reaching but we cannot, with confidence, continue using these tests as measures of individuals’ competency. We are diligently working on creating new exams and plan to begin measurement certification testing again in October 2023. We will provide updates here as we move through the process. Please see below for a list of Frequently Asked Questions.
Should you have any information about anyone improperly sharing the exam, please call our tip hotline at 828-348-0185 ext 413.
If you have additional questions, please send an email to exam-securityatnrppdotinfo . We expect a high volume of inquiries and it may take up to 72 hours to receive a response. Thank you in advance for your patience.
We appreciate your continued support of NRPP.
