  1. Christian

    I liked the course. It was easy to follow. I never lost interest. The instructor kept you engaged and it felt like the questions from the students were always questions that I was interested in asking myself. Great job.

  2. Ger

    A reliable resource and information that I could continually use. I love how some quiz results gives you not just the answers, but the formula. I highly recommend it.

  3. Jedd

    It is great to have such knowledgeable trainers in the course.

  4. Lynn

    Thank you so very much. This course was thorough! I would recommend it for anyone who is thinking of taking a certification exam. I had taken a radon course in the 1990s and was certified back then but I let my certification lapse because I did not have much radon testing work. This course was a great refresher and I feel well prepared for the certification exam and future testing work.

  5. Ed

  14. Marcus

    I really enjoyed the course. The instructor kept it interesting and funny. The videos, additional resources, and quizzes were all easy to navigate. I plan to refer back to this course frequently.

    Excellent course. My only complaint is that when going through the devices, I felt like it was a bit more fast paced since those in the class were already familiar with the devices. Being someone that only briefly knows about charcoal devices, it was difficult to get through that specific section. In addition, there was no powerpoint PDF for the NJ section. I felt the video was not very helpful in determining many of the differences. A clear list of differences would have been more useful. But overall, the course was well put together and the quizzes were beyond helpful.
