The easy-listening format of the audio Instruction includes interviews with experts in the radon industry providing you with insight into their experience as well as substantive technological and practical information. With an impressive 92% passing rate on the certification exams, these courses have proven to be successful and popular in preparing students for the certification exam and for conducting business.

One of the favorite aspects of this course is the opportunity for students to apply their skills with oversight and mentoring advice from a course instructor.  This is done in the "Field Exercises" at the end of the course in which the student identifies a house that can be used and has had a radon test performed (typically the student’s home or a home of a friend or relative).  The student then designs a system based upon knowledge they have obtained in the course, which is reviewed in a one-on-one conversation with the Lead Instructor.  The student then installs the system, taking photos throughout the process and of the final system, which are then reviewed in another one-on-one discussion with the Lead Instructor where additional helpful tips and practices are provided.   This approach has proven to be very successful as it reinforces the educational content with a meaningful hands-on experience with the assistance of a seasoned practitioner.  As an added benefit it provides a research house to study during different seasons, as well as pictures of a house you have mitigated for use in marketing.   Alternatively, if you currently work for a company that installs mitigation systems, photos of systems you have installed can also be a basis for discussions with the CERTI instructor to fulfill your field exercise.  Other options are also available that can be custom fit to your situation or business plan.

There is approximately 20 hours of coursework, including listening to audio instruction (in short audio tracks so you can listen to as many or as few as you want at any time); online resources such as videos, protocols, and publications; and quizzes that are taken as you progress through the course (not timed and may be taken unlimited times), plus the time for your field exercises.  There is no time limit for taking the course, and even after completion you continue to have access to the course in order to refer back to resources.

CERTI students also have access to business tools such as sample contracts, and warranties.  We are also available by phone during and after the course for any questions concerning the course or radon situations you come across on the job.

Michael said: this is the second time for me on this course. It makes way more sense now! recommend everyone review this every few years. CERTI Comment: This individual took the course but waited too long to apply for certification. There is a lot of content in the course to prepare people, which is why it is also a basis of a Continuing Ed course. So once you complete the course apply for certification and then come back and review before test or take the CE version for your next renewal.
