  1. During a mold inspection of a multi-family dwelling, a CMA observes condensation regularly forming on interior window surfaces in winter. What is the PRIMARY underlying cause of this mold-risk condition?

    Answer: Warm, humid interior air contacting cold window surfaces below the dew point

    Condensation on windows occurs when warm, humid indoor air contacts a cold surface that is at or below the dew point temperature, providing moisture for mold growth.

  2. A CMA is asked to inspect a building where occupants report health symptoms only on weekdays. What should this pattern lead the CMA to investigate first?

    Answer: The HVAC system settings, including weekday versus weekend operation schedules

    Symptoms occurring only during work hours strongly implicate the building's HVAC system, which may operate differently on weekdays and distribute mold spores or VOCs.

  3. Under Florida Statute 468, which of the following is PROHIBITED for a licensed Mold Assessor?

    Answer: Performing or offering to perform mold remediation on the same project being assessed

    Florida law prohibits a licensed mold assessor from performing or offering remediation on the same project to prevent conflicts of interest that could compromise assessment objectivity.

  4. A CMA is inspecting a building and finds Chaetomium in a surface sample from water-damaged drywall. What does this identification indicate?

    Answer: There has been significant and likely prolonged cellulose-rich material wetness

    Chaetomium is a water-damage indicator mold that colonizes cellulosic materials under sustained wet conditions, and it can produce mycotoxins.

  5. When interpreting an air sample result, a CMA finds that the indoor Aspergillus/Penicillium spore count is significantly higher than the outdoor count. What is the MOST appropriate conclusion?

    Answer: The elevated indoor count suggests an active indoor mold amplification source requiring investigation

    Indoor Aspergillus/Penicillium counts substantially exceeding outdoor baseline levels indicate an indoor amplification source that must be located and addressed.

  6. A CMA is collecting air samples in a building with a forced-air HVAC system. At what point relative to HVAC operation should samples typically be collected for a worst-case assessment?

    Answer: While the HVAC system is actively running to distribute any mold spores present

    Collecting samples while the HVAC system is running captures spores being actively distributed throughout the building, reflecting actual occupant exposure conditions.

  7. What is the significance of observing 'ghost marks' or 'ghosting' on walls and ceilings during a mold inspection?

    Answer: They are dark sooty patterns along framing or airflow paths indicating particulate deposition and possible mold growth on or within walls

    Ghosting patterns result from particulates and bioaerosols depositing along structural members or air-leakage paths, often correlating with moisture infiltration and mold growth in cavities.
