1. A mold assessor in Florida observes a musty odor in a building but cannot see any
visible mold growth. The client requests a mold inspection report. Under FS 468.84, what
is the assessor’s most legally appropriate next step?
a) Issue a clearance certificate stating no mold exists because none is visible
b) Recommend destructive testing to open all wall cavities immediately
c) Perform a moisture mapping and collect air or surface samples in accordance with
their scope of work
d) Decline to write a report until mold is visually confirmed
Correct Answer: c
Rationale: Florida law requires mold assessors to base their assessment on a defined
scope of work. Odor indicates possible hidden mold; sampling (air or surface) is
permissible to identify contamination patterns. Clearance certificates require
documented evidence, and destructive testing requires client consent and justification.
Avoiding reporting due to lack of visibility contradicts professional standards.
2. Which of the following is specifically prohibited for a Florida-licensed mold assessor
under Florida Statute 468.841(2)?
a) Collecting air samples for spore trap analysis
b) Referring a client to a specific mold remediator whom the assessor owns
c) Using thermal imaging to detect moisture
d) Preparing a written mold remediation protocol
,Correct Answer: b
Rationale: Florida law prohibits a mold assessor from having a financial interest in a
mold remediation company they refer clients to, as this creates a conflict of interest.
Collecting samples, using thermal imaging, and writing protocols are allowed within the
assessor’s scope.
3. A mold assessor takes three air samples inside a home and one outside. The outdoor
sample shows 500 spores/m³ of Cladosporium. Indoor samples range from 200 to 400
spores/m³ of Cladosporium. The assessor concludes no abnormal fungal growth. This
conclusion is:
a) Correct, because indoor levels are lower than outdoor
b) Incorrect, because outdoor should be the lowest of all samples
c) Correct, but only if Stachybotrys was also tested
d) Incorrect, because Cladosporium indoors should be zero
Correct Answer: a
Rationale: In mold assessment, outdoor air is used as a baseline. Indoor levels lower
than or similar to outdoor generally suggest no significant indoor amplification.
However, certain toxigenic species require additional interpretation, but for
common Cladosporium, lower indoor is typical.
4. Under Florida Administrative Code 64E-26.003, what is the minimum amount of
general liability insurance a licensed mold assessor must carry?
a) 100, 000𝑏)250,000
c) 500, 000𝑑)1,000,000
Correct Answer: d
Rationale: Florida requires mold assessors and remediators to carry $1 million in general
liability insurance to protect consumers from potential damages during assessments or
remediation oversight.
5. A mold assessor is hired to perform a post-remediation verification (PRV). The
remediation contractor states all work is complete. The assessor’s visual inspection
,reveals no visible mold, but moisture meter readings remain elevated in a previously
water-damaged drywall section. What should the assessor do?
a) Issue a clearance report since no mold is visible
b) Require further drying and re-inspection before clearance
c) Collect tape lift samples only from clean areas
d) Assume the moisture is from humidity and clear the job
Correct Answer: b
Rationale: PRV requires both visual and moisture verification. Elevated moisture
indicates potential for resumed mold growth. Clearance should only be given when
materials are dry to established standards (e.g., <15-16% moisture content for drywall
per industry guidelines).
6. Which sampling method is specifically recognized by the Florida Mold Assessor
licensing exam as appropriate for identifying culturable fungi?
a) Spore trap (impaction)
b) Tape lift
c) Agar plate (settle plate)
d) Swab sample plated on malt extract agar
Correct Answer: d
Rationale: Swab samples can be cultured to identify viable fungi. Spore traps and tape
lifts show morphology but not culturability. Settle plates are not quantitative for
assessment per EPA guidelines. The exam emphasizes that cultured samples (swab, bulk,
or air on agar) identify live fungi.
7. A mold assessor in Florida is an employee of a company that also offers mold
remediation. The assessor performs an assessment and then writes a remediation
protocol for the same building. Under Florida law, this is:
a) Permissible if disclosed in writing
b) Permissible if the assessor does not perform the remediation
, c) Prohibited regardless of disclosure
d) Permissible only on buildings over 10,000 sq ft
Correct Answer: c
Rationale: Florida law prohibits a mold assessor from being an employee of a
remediation company or from performing both assessment and remediation on the
same project to avoid conflict of interest, with limited exceptions for certain property
types. FS 468.8414 explicitly forbids this arrangement.
8. What does a “fungal ecology” assessment include beyond spore counts?
a) Identification of bacterial contamination
b) Evaluation of moisture sources, building materials, and conditions favoring growth
c) Asbestos testing
d) HVAC efficiency rating
Correct Answer: b
Rationale: Fungal ecology refers to understanding the relationship between moisture,
substrate, temperature, and mold growth. The assessor must identify conditions
promoting mold, not just quantify spores.
9. A homeowner requests a mold inspection to “clear” a property after a small bathroom
leak that was dried within 48 hours. There is no visible mold or odor. The assessor
should:
a) Collect multiple air samples to rule out hidden mold
b) Document no visual evidence of mold growth and state that no remediation is
indicated
c) Require a full remediation protocol before issuing any document
d) Recommend demolition of bathroom tiles
Correct Answer: b
Rationale: Mold assessment is based on evidence. Without signs of mold or water
damage, no further action is required. The assessor can legally provide a report stating
