Accredited Certifications


Indoor Sciences specializes in preparing students for industry-leading certifications from organizations such as ABIH and ACAC.  Certifications are one method to demonstrate your knowledge to clients and peers. But not all certifications are created equal.  In fact, many certifications are non-accredited and hold little weight in a court of law. Stop sifting through dozens of meaningless certifications and target high-end, accredited designations.

Why Indoor Sciences? 


In the indoor environmental field of study, there are many gray areas and competing voices. That means it is extremely important to trust your instructors.  Many teachers are ultimately trying to sell you a product or service.  Others take opinionated stances on controversial topics.  You need instruction that balances all sides of important issues without any conflicts of interest.   You can trust Indoor Sciences to deliver training that values technical accuracy, balanced viewpoints, and easy-to-understand instruction.
