Try these 10 sample questions from the Lead Supervisor Certification Exam practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

  1. 1A child has lived near peeling lead paint but shows no obvious immediate symptoms. What can the supervisor infer from the absence of symptoms?

    1. A. Lead exposure requires observable learning or behavior problems.
    2. B. Lead exposure remains possible without obvious immediate symptoms.
    3. C. Lead exposure requires measurable slowing of growth or development.
    4. D. Lead exposure requires observable hearing or speech problems.

    Answer: B

    Explanation: CDC states, "Most children have no obvious immediate symptoms." Learning, growth, and hearing problems are possible effects, but none must be visible before exposure can occur.

    Reference: CDC, Lead Exposure Symptoms and Complications — What to look out for, childhood exposure paragraph

  2. 2A contractor is hired specifically to eliminate a lead-based paint hazard permanently. How does Wisconsin classify the project?

    1. A. Abatement
    2. B. Interim control
    3. C. Cleaning verification
    4. D. Minor repair and maintenance

    Answer: A

    Explanation: DHS 163.03(1) defines abatement as "any measure or set of measures intended to permanently eliminate lead-based paint hazards". That permanent purpose makes A correct; the other choices describe temporary control, a post-renovation protocol, or a limited repair.

    Reference: Dhs 163 — DHS 163.03

  3. 3An occupied building's proposed containment blocks the only emergency exit. What must the supervisor do?

    1. A. Proceed if warning signs are posted
    2. B. Redesign containment so it does not interfere with emergency exit
    3. C. Lock the exit during work hours
    4. D. Allow occupants through the active work area

    Answer: B

    Explanation: DHS 163.14(1)(e)3 states, "Containment may not be constructed in a manner that would interfere with emergency exit." B corrects the prohibited design and preserves safe egress.

    Reference: Dhs 163 — DHS 163.14

  4. 4Which post-work process makes a final determination that work and final cleaning were completed and dust-lead levels are below Wisconsin clearance levels?

    1. A. Cleaning verification
    2. B. Clearance
    3. C. Pre-cleaning
    4. D. Interim certification

    Answer: B

    Explanation: DHS 163.03(14) says clearance makes "a final determination that the work was completed, final cleaning was conducted and dust-lead levels are below the clearance levels." Cleaning verification is a different renovation protocol, so B is correct.

    Reference: Dhs 163 — DHS 163.03

  5. 5Which description matches Wisconsin's definition of direct supervision?

    1. A. Available by telephone within one hour
    2. B. On-site and readily available to observe and assist
    3. C. Present only for setup and final cleaning
    4. D. Reviewing records after the work is complete

    Answer: B

    Explanation: DHS 163.03(25) defines direct supervision as "supervision by an individual who is on-site and readily available to observe and assist." Only B includes both required elements.

    Reference: Dhs 163 — DHS 163.03

  6. 6Before planning replacement of a lead-painted window assembly, the supervisor inventories its components. Which group consists of window-system parts identified by HUD?

    1. A. Sash, stop bead, parting bead, and jamb.
    2. B. Sash, tread, riser, and window jamb.
    3. C. Stop bead, stair tread, newel, and riser.
    4. D. Parting bead, stair riser, newel, and tread.

    Answer: A

    Explanation: HUD states that the term window applies to "the sash, the stop and parting beads, and the window jambs." The other groups mix window terms with stair components.

    Reference: HUD, Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, Chapter 12 — Figure 12.3a

  7. 7A worker briefing covers health effects that high adult lead exposure may cause. Which listed effect specifically involves kidney function?

    1. A. Kidney damage affecting the renal system.
    2. B. Anemia affecting the blood-forming system.
    3. C. Neurologic damage affecting the nervous system.
    4. D. Infertility affecting the reproductive system.

    Answer: A

    Explanation: CDC/NIOSH lists "Kidney damage" among effects of high lead exposure in adults. The other options are also real adult lead effects, but they concern blood, nerves, and reproduction rather than kidney function.

    Reference: CDC/NIOSH, About Lead in the Workplace — Health effects from high lead exposure

  8. 8A project is intended only to reduce a lead hazard temporarily. Under DHS 163, which classification is most accurate?

    1. A. Abatement
    2. B. Interim controls
    3. C. Clearance
    4. D. Lead-free inspection

    Answer: B

    Explanation: DHS 163.03(58m) defines interim controls as measures designed to "temporarily reduce human exposure or likely exposure" to lead-based paint hazards. B fits that temporary purpose; abatement is permanent, while clearance and inspection are evaluation activities.

    Reference: Dhs 163 — DHS 163.03(58m)

  9. 9Before work, what should be done with movable furniture and rugs in the work area?

    1. A. Cover them in place without cleaning
    2. B. Remove them from the work area
    3. C. Place them at the containment entrance
    4. D. Move them after clearance sampling

    Answer: B

    Explanation: DHS 163.14(1)(e)4.a directs, "Remove all objects that can be moved from the work area, including furniture, rugs, and window coverings." B follows that instruction.

    Reference: Dhs 163 — DHS 163.14(1)(e)4.a

  10. 10What is the outer deadline, measured in working days after completion, for the supervisor's written abatement report?

    1. A. 10 working days
    2. B. 20 working days
    3. C. 30 working days
    4. D. 45 working days

    Answer: B

    Explanation: DHS 163.14(1)(m) says the report is due "Within 10 working days after receiving the clearance report, but no later than 20 working days following completion of abatement". B is the outer limit; the first trigger can make it due earlier.

    Reference: Dhs 163 — DHS 163.14
