Council-Certified Microbial Consultant

Prep Course

What is the CMC certification? 

The Council-Certified Microbial Consultant (CMC) is a high-level certification for professionals that are experienced at inspecting properties for mold. The certification is offered by the American Council for Accredited Certification (ACAC). Our company, Indoor Sciences, offers a CMC preparatory course called the Microbial Investigator Course.

The CMC is the most prestigious certification for mold inspection in the industry, bar none.  Consider getting this accredited certification today!

What are the CMC prerequisites? 

Not everyone qualifies to become a Council-certified Microbial Consultant (CMC). The ACAC requires applicants to have 8 years of field experience in mold inspection and sampling.  They reduce the experience requirement to 4 years if you have a 4-year college degree in science, engineering, or related field or 6 years if you have a 2-year college degree in science, engineering, or related field. If you are new to the field and have less experience, you may want to target the non-accredited CSMI certification which requires no experience. Or if you only have 2 years of experience, you should consider the accredited certification that is one step below, the CMI.

Experience is documented by filling out project sheets which are part of the CMC application. If you have questions about your experience meeting the requirements, we suggest you contact the ACAC at (623) 582-0832.

What is the exam like? 

The CMC exam is offered through computerized testing centers found around the world. There is also a newer option to take the exam online with a proctor viewing you through a webcam. 

The following are important details related to the CMC examination:

  • All multiple choice questions with four possible answers
  • 120 total questions
  • Passing grade is 75%
  • Duration: 3 hours 
  • Closed-book exam

How do I prepare for the CMC exam? 

Thousands of students have prepared for the CMC certification by taking our Microbial Investigator Course, which is sometimes referred to as the “CMC Course”.  In fact, we guarantee that students taking our course will pass the CMC! Indoor Sciences is a training provider of the Indoor Air Quality Association (IAQA) and has been hired by governmental agencies and clients around the world to teach this class. Because this is an accredited certification, we do not receive a copy of the exam.  However, for over a decade we’ve had a high degree of success helping students pass the CMC exam on the first try. 

The Microbial Investigator Course, which prepares you for the CMC exam, is both offered as an online and onsite course.  For more information including pricing and upcoming training dates, visit the Microbial Investigator Course.
