NISCR's online Applied Structural Drying (ASD) certification lets you master the science of drying buildings on your own schedule, with a same-day certificate on completion. Across Tennessee's humid climate, knowing how to read psychrometrics, place air movers, and dry structures correctly is what separates a clean restoration from a callback for mold, making this credential valuable to restoration firms statewide.

Licensing
Do you need a license in Tennessee?
Applied structural drying is a technical skill set and is generally not separately licensed in Tennessee. However, drying work is usually part of a larger water or mold restoration project, and those broader projects can fall under Tennessee contractor licensing once they reach the state's $25,000 threshold, or under a Home Improvement license in certain counties. Your NISCR certificate is a professional credential, not a government license. Always confirm current state and local requirements with the Tennessee Board for Licensing Contractors before performing regulated restoration work.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.

The applied structural drying market in Tennessee
Tennessee's hot, muggy summers and high ambient humidity make proper drying genuinely difficult, and improper drying is a leading cause of secondary mold growth in the state. After events like the 2010 Nashville flood and routine storm-driven losses across the Cumberland Plateau and Mississippi River basin near Memphis, firms need technicians who can dry structures fast and verify results, keeping ASD-trained workers in steady demand.

Curriculum
What you’ll learn
- Read a psychrometric chart to track temperature, relative humidity, GPP, and dew point through a drying job.
- Calculate the number of air movers and dehumidifier capacity a structure requires based on affected area and class of water.
- Choose between refrigerant, LGR, and desiccant dehumidifiers for the conditions and load on site.
- Design directional airflow that moves moisture off surfaces and into the dehumidification system efficiently.
- Apply controlled drying to wet materials — drywall, framing, hardwood, and concrete — instead of premature removal.
- Use moisture meters, hygrometers, and data loggers to establish a dry standard and confirm materials reach it.
