Steps for Radon Certification

Radon Certification CardMany radon professionals find it valuable to be certified in the radon field in order to provide assurance to their clients that they are receiving services that are within standards, ethics and protocols that can be relied on.  It has especially become important to have the certification in order to provide services during real estate transactions (which account for approximately 70% of radon testing and mitigation).

The professional recognition you and your business receive from being nationally or state certified is an integral part of the professionalism and excellence we provide in our training programs.  We are committed to providing you, your business, and your clients with the assurance that the extra efforts you take in holding a national or state certification means your qualifications are of the highest standards.

Steps for Certification:

At CERTI we provide you with quality training and easy steps to becoming certified and maintaining your certification.

Measurement Provider

Mitigation Provider

  • Successfully complete the Measurement and Mitigation Entry Level Courses
  • Take the appropriate Certification Exams.  Since both measurement and mitigation courses are a requirement, you have the option of taking both measurement and mitigation certification exams to get both certifications or taking just the mitigation certification exam to get just the mitigation certification.  
  • Complete the Certification Application and return to NEHA NRPP.

What’s New?

Attention Students!! Great News!

We are in the process of updating our site to provide you better access to resources and courses. We think you will be pleased with the upcoming changes.
Unfortunately, to make this happen the site will be down as follows:  Midnight Sun Sep 21 - Midnight Sun Sep 28

In the meantime, if you need access to coursework during that time frame (audio, video, or course manuals) you can download those files directly to your computer ahead of time and access them locally.

Please let us know if you have any concerns or needs about this or any other aspect of your coursework. We will be happy to assist you.
