The Mold Removal Specialist Certification is not Accredited, while the new Mold Remediation Specialist Certification is Accredited by the ANSI National Accreditation Board (ANAB).

The overall content of the Examination is similar but updated in a Job Task Analysis conducted in 2021.

Before your expiration date, you will need to apply for the ANAB Accredited Mold Remediation Specialist Certification, take the Examination, and pass with a 79% or higher to stay certified.

The overall subject matter of the MRS Examination did not change, and we plan for nothing to change with Florida or any other state/city licensing program.

The hope with Accreditation is that it will bring recognition to the Certification, and other cities and states may include the Certification as a part of their licensure programs.

Each county, city, and state have different local laws and regulations regarding operating a mold remediation company. Please check with your local government to obtain details on business requirements.

If you are based in Portland, Oregon, Washington, D.C., or the State of Florida, please click here for more information on license requirements.

The ANSI National Accreditation Board (ANAB) has Accreditation programs that operate in accordance with international guidelines and have been verified by government and peer review assessments.

Being ANAB Accredited assures the IICRC’s competence and reliability regarding our Mold Remediation Specialist (MRS) Certification program. It shows that the IICRC sustains continual improvement through assessment of system effectiveness, efficiency, and competence as well as promotes consistence and demonstrates equivalence of assessments via mutual recognition based on peer review.
