How it works

This unofficial EPA lead inspector practice test holds 138 questions on the lead-based paint inspector's job, written from 40 CFR Part 745 and two EPA lead pages, read October 9, 2026. Each answer names its section.

Read the full guide

What the questions cover

Eight topics follow the inspector course list in 40 CFR 745.225(d)(1): the inspector's role, lead and its health effects, the federal and state rules, choosing rooms and components, paint, dust and soil sampling, action levels and testing, the inspection report and recordkeeping. The bank does not cover how to operate an XRF analyzer.

Practice only, with no pass mark

Section 745.226 prints no question count, time limit or pass mark for the certification exam. Exam mode draws 40 questions, which is this site's choice, and shows a score with no pass or fail.

  • Keep the two jobs apart: an inspection finds lead-based paint surface by surface, and a risk assessment finds hazards and gives options.
  • Learn the dust-lead action levels in force since January 12, 2026: 5 for floors, 40 for interior window sills, 100 for window troughs, in µg/ft².

Questions and answers

Is this the EPA lead inspector exam?

No. It is unofficial practice, not affiliated with the U.S. Environmental Protection Agency or any state lead program, written from the federal rule and EPA's pages. No question comes from a certification exam.

How do you become a certified lead inspector?

Under 40 CFR 745.226(b), complete an accredited inspector course, pass the certification exam and apply to EPA. The rule asks inspectors for no further education or experience. A state with its own authorized program sets its own steps.

How long is the lead inspector course?

40 CFR 745.225(c)(6) sets a minimum of 24 training hours for the inspector course, with at least 8 hours of hands-on training. The inspector refresher course lasts at least 8 training hours.

How many times can you take the lead inspector exam?

No more than three times within 6 months of receiving the course completion certificate, under 40 CFR 745.226(b)(6). Someone who has not passed and been certified by then retakes the course before reapplying.

Does the federal lead inspector rule apply in every state?

No. Under 40 CFR 745.220(b) it applies only where no state or tribal program is authorized. An authorized state certifies its own inspectors and may ask more than the federal rule, so check with your state's lead program.
