Indoor Environmentalist Course


Who should take this course?

If you are looking to obtain a prestigious indoor air quality certification such as the CIE or CIEC, you don’t want to miss this course, often referred to as the “CIE Course”.  Or maybe you are most interested in learning how to thoroughly evaluate the indoor air quality of residential, commercial, and institutional buildings.  Whether your interest is certification prep or learning how to perform exceptional fieldwork, our Indoor Environmentalist Course is the right class for you.

While preparing for the CIE, CIEC, and CRIE certifications, you will learn how to ask the right questions, inspect important areas, and measure meaningful contaminants.

Is this an online course or an on-site course?

Both! You can start the online class today or check our course schedule below for upcoming dates. 


The online class consists of videos that you watch at your own pace, any time of day or night. It takes about 32 hours to complete the online course. Online students get access to the videos for 90 days and indefinitely keep the course manual for future reference. 


Online Registration


Our face-to-face, on-site courses are condensed down into two 8-hour days for a fast-paced format. The on-site class gives students the opportunity to use IAQ instruments hands-on. The class is typically taught quarterly in cities throughout the US. See below for upcoming class dates.
