ASSESSOR CERTIFICATION EXAM
STUDY GUIDE Practice Questions with
Detailed Answers, Rationales, and
Regulatory Updates for 2025-2026
Section 1: Regulatory Framework and Definitions (Questions 1-25)
Q1: Which federal regulation establishes the requirements for lead-
based paint activities, including risk assessor certification?
A) 40 CFR Part 745
B) 29 CFR Part 1926
C) 24 CFR Part 35
D) 42 USC Section 7401
Correct Answer: A) 40 CFR Part 745
Rationale: 40 CFR Part 745, Subpart L, establishes the EPA's lead-based paint
activities program, including certification requirements for inspectors, risk
assessors, and abatement supervisors. 29 CFR Part 1926 covers OSHA
construction standards, and 24 CFR Part 35 addresses HUD requirements for
federally-assisted housing .
Q2: What is the primary purpose of a lead risk assessment as defined
by EPA?
,A) To identify all lead-based paint in a dwelling
B) To determine the presence and location of lead-based paint hazards
C) To evaluate the structural integrity of a building
D) To estimate the cost of property renovation
Correct Answer: B) To determine the presence and location of lead-
based paint hazards
Rationale: A risk assessment is an on-site investigation to identify lead-based
paint hazards specifically, not just the presence of lead-based paint. Unlike an
inspection (which identifies all LBP), a risk assessment evaluates hazards that
pose an exposure risk .
Q3: What is the definition of "target housing" under EPA regulations?
A) Any housing built before 1950
B) Any housing receiving federal assistance
C) Any housing built before 1978, except housing for the elderly or persons
with disabilities (unless children under 6 reside there)
D) All rental properties regardless of construction date
Correct Answer: C) Any housing built before 1978, except housing for
the elderly or persons with disabilities (unless children under 6 reside
there)
Rationale: Target housing is defined in 40 CFR 745.103 as any housing
constructed before 1978, with specific exemptions for housing designated for
elderly persons or persons with disabilities (unless children under 6 reside
there) and zero-bedroom dwellings .
Q4: Which law originally required disclosure of lead-based paint
hazards in residential property transactions?
,A) TSCA Title IV
B) The Residential Lead-Based Paint Hazard Reduction Act of 1992 (Title X)
C) The Clean Air Act
D) The Safe Drinking Water Act
Correct Answer: B) The Residential Lead-Based Paint Hazard Reduction
Act of 1992 (Title X)
Rationale: Title X of the Housing and Community Development Act of 1992
(also known as the Residential Lead-Based Paint Hazard Reduction Act)
established the requirement for disclosure of lead-based paint hazards in
residential property transactions built before 1978 .
Q5: What is the EPA's Action Level for lead in drinking water?
A) 0.005 mg/L (5 ppb)
B) 0.010 mg/L (10 ppb)
C) 0.015 mg/L (15 ppb)
D) 0.020 mg/L (20 ppb)
Correct Answer: C) 0.015 mg/L (15 ppb)
Rationale: The EPA's Action Level for lead in drinking water is 0.015 mg/L (15
parts per billion). When levels exceed this threshold, water systems must take
corrective action, including public notification and treatment modifications .
Q6: What year was lead-based paint banned for residential use in the
United States?
A) 1950
B) 1968
C) 1978
D) 1985
, Correct Answer: C) 1978
Rationale: The Consumer Product Safety Commission banned lead-based
paint for residential use in 1978. This is the cutoff year used for determining
target housing and disclosure requirements .
Q7: Which of the following is NOT considered target housing?
A) A single-family home built in 1965
B) An apartment building built in 1975 with a child under 6 in one unit
C) A zero-bedroom dwelling (studio apartment)
D) A child-occupied facility built in 1985
Correct Answer: C) A zero-bedroom dwelling (studio apartment)
Rationale: Target housing specifically excludes zero-bedroom dwellings
(studios/efficiencies) and housing for the elderly or persons with disabilities
(unless children under 6 reside there). Child-occupied facilities built before
1978 are also subject to regulation .
Q8: What is a "child-occupied facility" under EPA regulations?
A) Any daycare center
B) A building constructed before 1978 visited regularly by children under 6
C) Any school built before 1978
D) A facility where children under 6 spend more than 3 hours per week on
at least two different days
Correct Answer: B) A building constructed before 1978 visited
regularly by children under 6
Rationale: A child-occupied facility is defined as a building or portion of a
building constructed before 1978 that is visited regularly by children under 6
