The American Council for Accredited Certification offers the Council-certified Microbial Remediation Supervisor (CMRS) to individuals whose training and field experience in supervising microbial remediation projects warrant professional recognition. Additionally, ACAC offers the CMRS examination to certain license applicants in states where it is required by law.


Objectives of the CMRS Program:

  • To identify persons with acceptable knowledge of indoor air quality and the standards and regulations affecting Council-certified Microbial Remediation Supervisors


  • To award special recognition to those microbial remediation supervisors who have demonstrated verifiable field experience.


  • To qualify applicants for certain state licenses.




Candidates for the CMRS certification must possess one of the following combinations of five (5) years education and relevant field experience:
