Is the field of mold inspection new to you? If so, the Council-Certified Structural Mold Investigator (CSMI) is the ideal designation.


The CSMI is the newest mold-related certification from the American Council for Accredited Certification (ACAC).  This non-accredited certification is designed for people not meeting the 2 year experience requirement for the Certified Microbial Investigator (CMI).




According to the ACAC, the only prerequisite for the CSMI is employment in the field of indoor environmental investigation. Employment would also include work done by self-employed practitioners, but the certification board may request proof of active work.


If you have a few years of experience, you should consider the Certified Microbial Investigator (CMI).

Both the online and on-site classes above include the CSMI practice exam. If you would like to only take our CSMI practice exam without doing the whole course, the cost is $199. Click on CSMI Practice Exam to register. Please note that the practice exam does not explain why the correct answers are correct and the wrong answers are wrong.


How is the CSMI different from the CMI and CMC?


The CSMI is very similar to the CMI and the CMC examinations. The difference between the CSMI and the CMI/CMC are the required years of experience. The CSMI requires no experience while the CMI requires 2 years of documented experience and the CMC requires 8 years of experience. We have a single class that will equally prepare you for all 3 of these examinations. Don’t worry about our classes helping you pass the exams.  We guarantee your success!


How do I get certified?


After finishing our class, you’ll be prepared to take the ACAC certification exam for CSMI.  The exam itself is offered at computerized testing centers.  You can find a proctored testing location by clicking this link: Testing Locations
