"Well paced course and good visual aides to help understand the information being presented."

"Very Informative. I've been doing Radon testing for 20 plus years and thought I knew everything about Radon. I was wrong and I actually knew very little about Radon."

"The only place I will ever go for additional training is CERTI. It's been six years and all of my courses and information are still in my same portal so that I can access and refresh myself whenever needed. As good as it gets."

"I took this course to fulfill my continuing education credits and I'm glad I did.  There is simply so much information to remember and this course covers ALL of it!  I cannot say enough about the professionalism, completeness, and methodology of quizzes (which explain the answers gotten wrong so that you can learn from them!)" 

"This was an excellent course.  I went thru a different education provider during the initial licensing agreement but wish I would have known about this course then.  The level of content, supplemental resources, and the ability to go at my own pace was invaluable." 

“This was a great course. I appreciate the home page and that we can utilize this information even after completion. I really like the online course and the flexibility to complete the course. That works very well with my schedule.”
