The company has broken down the new S520 into five general principles of mold remediation: safety and health, project documentation, contaminant control, contaminant removal and contaminant prevention. The course covers mold issues, highlights of the S520, and principles of mold remediation. It does not cover hands-on mold remediation or applied microbial remediation.

Instead, the focus of the course is to offer an overview of the new standards and references in a way that's easily accessible.

Included with the class is a copy of the Standard and Reference Guide for Professional Mold Remediation S520. The S520 is the result of three years of collaborative effort on the part of dedicated volunteers from the public, institutional, and private sectors. Its purpose is to combine scientific principles with practical procedures for technicians facing real-life mold remediation challenges. Like the S500, it aims to create continuity in the delivery of services and help reduce the occurrence of poor practices.
