Choose your practice set

Questions are pulled at random and shuffled each time. You get a passing line of 70% — the same threshold as the real EPA 608 exam.

Study aid only. This practice exam is validated against EPA materials (subject-matter-expert reviewed 2026-06-04), but it is not the official certification exam and does not certify you. Take the real exam through an EPA-approved certifying organization — start at epa.gov/section608. Always defer to the official 608 manual and current EPA rules.
