What is a CMI?
A Council-certified Microbial Investigator (CMI) investigates microbial issues in the indoor environment. For example, a CMI can perform mold inspection, mold testing and bioaerosol sampling. A CMI can interpret lab results and design an effective remediation protocol. Finally, a CMI can perform post-remediation sampling to verify the success of a remediation project.
A CMI has verified knowledge in disciplines related to microbial investigations and sampling. The CMI examination covers a wide range of bioaerosols and their potential health effects. The CMI exam also deals with microbial sampling procedures and equipment.
Each CMI has demonstrated at least two (2) years experience in microbial sampling, mold inspection or mold testing in one or more of the following settings:
-
Offices and commercial buildings
-
Industrial structures
-
Government facilities
-
Schools and public buildings
-
Healthcare facilities
-
Residential structures
To earn the Council-certified Microbial Investigator designation, every candidate must:
-
Demonstrate at least two (2) years of verifiable field experience in microbial sampling (mold testing)
-
Pass a rigorous examination based on broad industry knowledge rather than a course curriculum
-
Earn the unanimous approval of the CMI certification board
-
Re-certify every two years
-
Participate in 20 hours of professional development activities each year
-
Maintain the highest ethical standards
The CMI certification is accredited by the Council for Engineering and Scientific Specialty Boards (CESB), a nationally recognized independent accreditation body. ACAC certifications are the ONLY designations in the indoor air quality field to earn CESB accreditation.
