What is a CMC?


A Council-certified Microbial Consultant (CMC) has earned the most respected certification in the field of microbial consulting.


To earn and maintain the CMC, every candidate must:


  • Demonstrate at least eight (8) years of verifiable field experience in microbial consulting

  • Pass a rigorous, psychometrically rated examination based on broad industry knowledge rather than a course curriculum

  • Earn the unanimous approval of the CMC certification board

  • Re-certify every two years

  • Participate in 20 hours of professional development activities per year

  • Maintain the highest ethical standards


The CMC 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.
