The 2022 course manual for the IICRC-approved Water Damage Restoration Technician certification — 18 hours of instruction and an optional exam, and the prerequisite for Applied Structural Drying, Applied Microbial Remediation and Commercial Drying Specialist. Built on the S500 fifth edition, it moves through the important S500 definitions, the general steps of a restoration project, the basic principles of drying, the properties of water, Categories and Classes, environmental microbiology, health and safety, restoration equipment, antimicrobials, psychrometry, the effect of water on materials, and contents. The manual notes that the IICRC reviews course manuals only for exam coverage, not for technical accuracy.
Why a contractor cares. This is the training every water tech on a job is presumed to have, and where the psychrometry and equipment selection a drying plan rests on are actually taught.
Why a public adjuster cares. When a carrier challenges drying duration or equipment count, the dispute is about the psychrometry in this curriculum — and knowing what the WRT does not cover shows how far a technician's certification actually reaches.
