Certified Microbial Investigator (CMI)

28 Hours / 2 Months / Mentor Supported

Course Overview:

Are you looking to get certified to do mold inspections? The most reputable mold certifications in the marketplace come from the American Council of Accredited Certification (ACAC).

The Certified Microbial Investigator (CMI) certification will demonstrate to your clients that you:

  • Understand when, where and why mold and bacteria will grow
  • Recognize the effects that mold and bacteria may have on health
  • Assess indoor environments in a comprehensive manner, rather than just collect samples
  • Comprehend how to diagnose microbial problems and write plans for them to be resolved
  • Apply an industry standards of care to your work
