Introduction:
The Louisiana Mold Remediation Contractor Exam – Classification 10 assesses the knowledge and skills
required to perform mold remediation work safely, legally, and effectively in the State of Louisiana. The
examination evaluates competency in state licensing requirements, the ANSI/IICRC S520 Standard,
moisture control principles, containment procedures, worker safety, and post-remediation verification.
Questions are presented in multiple-choice and scenario-based formats to test both foundational
knowledge and practical decision-making. Candidates must demonstrate the ability to apply technical
standards, interpret regulations, manage project risks, and exercise professional judgment in real-world
remediation scenarios. This assessment is designed to ensure that licensed contractors protect public
health, building occupants, and workers while complying with applicable laws and industry standards.
