Water Damage Restoration Technician study plan

Define the four IICRC water damage restoration principles and explain what each one prevents in a real loss

List the three ANSI/IICRC S500 water categories (Category 1 clean, Category 2 grey, Category 3 black) and give two contamination examples for each

Describe how water category can degrade over time and what conditions accelerate that degradation

Identify the four classes of water intrusion (Class 1 through Class 4) and match each to a typical room or assembly scenario

Build a one-page category-versus-class matrix from memory, then correct it against your study material

Explain the role of a moisture meter, thermo-hygrometer, and infrared camera in a standard assessment

Describe how to sketch a floor plan and mark affected versus unaffected materials before extraction begins

Sequence the initial response steps from safety check through emergency extraction

State the documentation items a technician must record at intake (source, category, class, affected area, readings)

Practice writing a short scope note for a simulated Category 2 loss in a hallway and bathroom

Describe extraction equipment types and when each is appropriate for carpet, hard floor, and cavity water

Explain the purpose of air movers and how airflow direction and placement affect drying

Compare refrigerant and desiccant dehumidifiers by operating principle and typical use case

State the difference between open drying and closed drying systems and when each is chosen

Identify safety controls for electrical equipment in wet environments

Explain the target drying conditions concept and how temperature, humidity, and airflow interact

Describe how to establish a drying goal and when a structure is considered dry

Calculate a simple psychrometric comparison using grain depression between affected and unaffected areas

List the daily monitoring actions a technician performs on an active drying project

Identify signs that drying is stalled and name two corrective actions

Classify common building materials as salvageable, conditionally salvageable, or non-salvageable after water exposure

Describe inspection and drying approaches for wall cavities, subfloors, and ceiling assemblies

Explain how carpet, pad, and hardwood respond differently to water and what determines removal

Outline containment and engineering controls used when a loss involves contaminated water

State when a technician must escalate to a supervisor or refer to a specialist

Describe mold growth conditions and the technician's role versus a remediation specialist's role

List personal protective equipment levels and match each to water category and task

Explain the purpose of containment barriers and negative air pressure on a contaminated job

Identify common safety hazards on water losses: slip, electrical, structural, and biological

Outline the steps for a final walkthrough and customer handoff after drying is complete

Review the full restoration workflow from emergency call through job close and identify gaps in your own notes

Practice explaining a category and class determination aloud in under two minutes

Answer 60 practice questions across all topics and log every miss with the underlying fact

Re-read the weakest two topic areas and rewrite your summary notes for them

Memorize the key numeric references you use most, such as drying goal thresholds and monitoring intervals

Complete two timed full-length practice exams and compare scores for improvement

Review only the error log and weakest topics rather than re-reading everything

Recite the category and class matrix and equipment selection sheet from memory

Prepare exam-day logistics: identification requirements, scheduling, and time allocation per question

Write a final one-page personal cheat sheet of facts you most often forget
