TEXAS MOLD REMEDIATION CONTRACTOR STATE EXAM — COMPLETE
SOLUTIONS (2025/2026)
Introduction
The Texas Mold Remediation Contractor license, regulated by the Texas Department of
Licensing and Regulation (TDLR), certifies professionals to safely assess and remediate
mold in buildings, protecting public health and property. Contractors must adhere to
TDLR rules to ensure compliance, minimize risks, and uphold standards during projects.
This exam covers core areas, including Texas Administrative Code (TAC) mold
regulations, remediation protocols and project management, containment setup and
negative air pressure, personal protective equipment (PPE), work plans, remediation
protocols, and post-remediation evaluation (PRE), licensing requirements, reporting, and
recordkeeping, liability, insurance standards, and homeowner rights, health risks, mold
identification, and environmental controls. Designed for the 2025/2026 licensing period,
this guide provides original, scenario-based questions with detailed explanations to
support complete mastery, formatted in Markdown for clarity.
Question 1
A mold remediation contractor is hired for a project in a Texas residence with visible
mold growth exceeding 25 contiguous square feet. Per TAC §78, what is the FIRST step?
A. Begin removal without assessment
B. Notify TDLR immediately
C. Ensure a Mold Assessment Report (MAR) is completed
D. Apply biocide without containment
Correct Answer: C — Ensure a Mold Assessment Report (MAR) is completed
Explanation: TAC §78.100 requires a licensed Mold Assessor to complete a MAR before
remediation for projects >25 sq ft, outlining scope and protocols. Removal without
assessment (A), immediate TDLR notification (B), or biocide application (D) violates
sequencing rules.
Question 2
During a remediation project, a contractor identifies additional mold in an HVAC system.
What must be done per TDLR rules?
A. Ignore if not visible
B. Amend the Mold Remediation Protocol (MRP)
C. Continue without documentation
D. Use unapproved cleaners
,Correct Answer: B — Amend the Mold Remediation Protocol (MRP)
Explanation: TAC §78.120 mandates amending the MRP for new discoveries like HVAC
mold, ensuring updated containment and removal plans. Ignoring (A), continuing
undocumented (C), or unapproved cleaners (D) risks non-compliance and health hazards.
Question 3
What is the minimum PPE requirement for workers in a containment area with Category 3
mold?
A. Gloves only
B. Full-body suit, respirator, gloves, and boots
C. No PPE needed
D. Mask and gloves only
Correct Answer: B — Full-body suit, respirator, gloves, and boots
Explanation: TAC §78.140 requires full-body protective suits, N95 or higher respirators,
gloves, and boots for Category 3 (extensive) mold to prevent exposure. Gloves only (A),
no PPE (C), or minimal (D) is insufficient.
Question 4
A contractor completes remediation. What is required for post-remediation evaluation
(PRE)?
A. No evaluation needed
B. Visual inspection and clearance testing by a Mold Assessor
C. Self-inspection only
D. Homeowner sign-off without testing
Correct Answer: B — Visual inspection and clearance testing by a Mold Assessor
Explanation: TAC §78.130 mandates PRE by a licensed Mold Assessor, including visual
checks and air/surface sampling to confirm mold removal. No evaluation (A),
self-inspection (C), or sign-off without testing (D) violates clearance rules.
Question 5
What is a key requirement for mold remediation work plans per TAC §78?
A. No written plan needed
B. Include containment, removal methods, and PPE
C. Verbal plan only
D. Ignore HVAC considerations
Correct Answer: B — Include containment, removal methods, and PPE
, Explanation: TAC §78.110 requires work plans to detail containment zones, removal
techniques, PPE, and disposal to ensure safe, effective remediation. No plan (A), verbal
(C), or ignoring HVAC (D) risks non-compliance.
Question 6
An employee develops a rash after mold exposure. What is the contractor’s
responsibility?
A. Ignore if mild
B. Report incident and provide medical evaluation
C. Continue work without PPE
D. Deny exposure occurred
Correct Answer: B — Report incident and provide medical evaluation
Explanation: TAC §78.150 requires reporting exposure incidents and offering medical
evaluation to comply with worker safety. Ignoring (A), no PPE (C), or denial (D) violates
regulations.
Question 7
What is the negative air pressure requirement for containment areas?
A. No pressure needed
B. Maintain -0.02 inches of water column
C. Positive pressure only
D. Variable without monitoring
Correct Answer: B — Maintain -0.02 inches of water column
Explanation: TAC §78.120 mandates negative pressure of at least -0.02 inches WC in
containment to prevent mold spore spread. No pressure (A), positive (C), or unmonitored
(D) risks contamination.
Question 8
A contractor must notify TDLR of a project if?
A. Mold <25 sq ft
B. Project >25 sq ft and requires MRP
C. All projects, regardless of size
D. Only commercial projects
Correct Answer: B — Project >25 sq ft and requires MRP
Explanation: TAC §78.100 requires notification for projects >25 sq ft needing a MRP.
Small projects (A), all projects (C), or only commercial (D) are incorrect.
