What is a CMI?
A Council-certified Microbial Investigator (CMI) has earned the most respected certification in the field of microbial investigation.
A CMI is certified as knowledgeable and experienced in all facets of microbial investigation, including the design and execution of sampling regimens.
To earn and maintain the CMI, every candidate must:
-
Demonstrate at least two (2) years of verifiable field experience in microbial investigation
-
Pass a rigorous, psychometrically rated 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. IAQ Council certifications are the ONLY designations in indoor air quality to earn CESB accreditation.
