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.
