New Jersey Certification

As of April 1, 2016, the Radon Section of the New Jersey Department of Environmental Protection (NJDEP) no longer administers the certification exams or maintain an approved list of initial and continuing education training courses.  NRPP administers the NJDEP exams through PSI Testing Facilities in New Jersey, New York, Pennsylvania, and Delaware. 

 A list of training providers who have been approved by NRPP to offer the initial New Jersey training are listed below.  For the annual continuing education requirements, those who are certified with the state of New Jersey are allowed to use any continuing education (CE) course approved by NRPP. Click here to be taken to the CE page.    

New Jersey law requires that the New Jersey Department of Environmental Protection (DEP) certify radon measurement and mitigation professionals.  There are four types of radon professional certification in New Jersey.  They are as follows:

Certification TypeInitial
Training Course
CE Requirements
Measurement Specialist24 hours  8 hours
Measurement Technician16 hours  4 hours
Mitigation Specialist24 hours  8 hours
Mitigation Technician16 hours  4 hours

Individuals who want to become a New Jersey certified radon professional must:

1.  Attend an entry-level training course approved by NRPP for the number of hours shown above, depending on the type of certification you are wanting to obtain.  Be sure to take a course that is approved for the State of New Jersey Certification.  At this time, the following training providers are approved to offer the additional training for New Jersey along with their regular NRPP entry-level radon certification course:

2.  Pass the New Jersey Certification Exam for the appropriate category.   All individuals, who take an entry-level course that is approved with the New Jersey certification materials, are able to take their appropriate exam through a PSI testing facility in New Jersey, New York, Pennsylvania, and Delaware.  Instructions on how to register with PSI are explained a little further down on this page.

3.  Affiliate with a certified radon measurement or mitigation business and obtain an affiliation letter from the business to submit with their initial application.

4.  Meet the requirement of the New Jersey Regulations for Certification of Radon Testers and Mitigators (N.J.A.C. 7:28-27) for the certification category. 

5.  Submit an initial New Jersey radon certification application.  Instructions can be found here.

Upon approval, an individual is issued a provisional certification to allow them to obtain six (6) months of radon work experience.  After six (6) months, the business with which the individual is affiliated must submit a letter to the Radon Section of the NJDEP documenting the individual’s radon work experience.  At that time the individual will become fully certified.

Annual Certification Renewal:

Annual New Jersey certification renewal is required for professionals.  A pre-printed version of the application will be sent to the mailing address in the NJDEP database.  The application needs to be reviewed for accuracy.  Any changes need to be documented on the application before returning the renewal application to the Radon Section of the DEP.  An individual is required to take continuing education (CE) for the number of hours shown in the table above depending on the certification category.

New Jersey certified professionals are allowed to take a NRPP approved CE Course as long as a continuing education course is approved and on the NRPP list.  

Study Materials:

Below is a list of materials that anyone who is planning to take one of the New Jersey DEP certification exams will need to review in order to familiarize yourself with New Jersey requirements and standards.  Because New Jersey has their own regulations, there will be some difference in the national standards that NRPP certified individuals are taught and follow. There will be New Jersey specific questions on the New Jersey Certification exams.
