ACAC Certifications

If you do an internet search for “mold certifications” or “indoor air quality certifications,” you’ll find a dozen, seemingly legitimate organizations.  Unfortunately, they are non-accredited certifications and they may actually harm your reputation among professionals in the field!


The American Council for Accredited Certification (ACAC) is the organization that offers the well-known, accredited certifications of CIE, CMR and CMI.  These ACAC certifications and others are accredited by the Council of Engineering & Scientific Specialty Boards.  In fact, a few states only allow ACAC’s certification exams to meet their licensing requirements!
