Below you’ll find the questions we are most frequently asked. If your inquiry is not answered here, feel free to contact us at (312) 920-9393.

What's the difference between an accredited and non accredited certification?

Accreditation is a process in which a third-party assesses the certification program and recognizes that the program is operated according to the high standards of the accreditation organization. Most ACAC certifications are accredited by The Council of Engineering and Scientific Specialty Boards (CESB) and/or the National Commission for Certifying Agencies (NCCA). The accreditation from these organizations makes ACAC certifications more valuable to you and your clients than non-accredited certifications. 

Does my experience qualify me for a certification?

If you have specific questions about your personal experience and if it qualifies for a specific certification, you should contact the certification board directly. You can contact the ACAC at (623) 582-0832.

Are there any spaces available for your upcoming on-site classes?

If the on-site class is still listed on our website, then seats are available. 

Do you have a discounted block of hotel sleeping rooms for your upcoming on-site class?

We typically do not set up blocks of discounted hotel rooms for our on-site classes.

Does completing your class mean I am "Certified"?

No. Indoor Science is a training provider, not a certifying agency. We do not issue certifications ourselves. Our classes are designed to prepare you to pass accredited certification exams from organizations such as ACAC and ABIH. Much like taking a drivers ed class, once you finish the class you don’t have your drivers license. Many of our classes are sponsored by the Indoor Air Quality Association (IAQA) and they issue the certificates of completion (which are not a “certification”).

I've finished the class, how do I become certified?

Congratulations on finishing our course! The next step in the process is to reach out to the ACAC and complete their application form. Once your application has been completed, you will coordinate a time with them to schedule your certification exam. Exams are offered at computerized testing centers around the world. Upon passing the exam, your completed application will be sent to the ACAC Board for approval. Typically the Board meets once a month.  You are not officially certified until you receive word from the ACAC’s Board.

How long do I have to finish your online class?

Our classes provide you with 90 days of full access. After the 90 day period is completed, you may purchase a 90-day extension if you need more time.  To purchase an extension, please email us for a registration link or call us at (312)920-9393.
