A CMRS can design remediation protocols or follow established protocols and industry standards.

A CMRS has verified knowledge of the microbial remediation field. The CMRS examination covers the most respected reference texts in the industry. Candidates for the CMRS must know the important industry standards. They must be familiar with scientific principles governing mold and the indoor environment. They must understand the most common practices and protocols used by remediators. They must be familiar with the equipment used in mold remediation. They must be aware of legal issues affecting their work Each CMRS has demonstrated at least five years experience in mold remediation and mold removal in one or more of the following settings: offices and commercial buildings; industrial structures; government facilities; schools and public buildings; healthcare facilities; and residential structures.

The Indoor Air Quality Council launched the credential in 1999. In 2006, the Council discontinued membership services and focused exclusively on credential program. In 2008, the Council broadened its focus to other industries and changed its name to the American Council for Accredited Certification (ACAC). 

For healthy homes-related credentials, ACAC offers credentials in two broad categories: indoor environment and microbes. Microbes primarily consist of mold and bacteria. In the microbes category, ACAC offers six credentials:

  • Three credentials for individuals who investigate microbe and mold issues and takes samples: a Consultant, an Investigator, and Residential Mold Inspector. A Consultant has eight years of experience while an Investigator only has two years of experience. A Residential Mold Inspector locates and identifies mold as part of a home inspection usually during a real estate transaction.
  • Two credentials for individuals who conduct mold remediation and mold removal projects in the indoor environment: a Supervisor and a Remediator. A Supervisor has five years of experience while a Remediator has only two years of experience.
  • Claims Adjustor credential for the individuals who establishes and maintains good air quality in the built environment. The CIAQM requires two years of property management experience.

Three cautions:

  • Individuals and not firms are credentialed. Therefore, make sure the individual who is credentialed directly supervises the radon mitigation work.
  • Several states require additional certification or licensing for individuals conducting mold remediation. Check with your state.
  • If you have a complicated problem, make sure you have the more experienced Council-certified Microbial Remediation Supervisor conducting the investigation.
