EPA 608 practice quiz (US)

Practice only, not the EPA exam. These are original questions written from public U.S. EPA Section 608 rules (40 CFR Part 82, Subpart F) as summarised on epa.gov, checked November 2026. They are not real exam questions. Independent study guide; not affiliated with or endorsed by the U.S. EPA. Rules change; check epa.gov and your certifying organisation. Nothing you enter is sent or saved. The quiz is in English only, like the exam.

10 questions each for Core, Type I, Type II and Type III. Check one section at a time or all 40 at once. Each answer comes with a short explanation.
