Key Takeaways

The EPA Section 608 exam is moderately easy for prepared students. It is open-book for the Core and Type sections, requires about 70% to pass, and most candidates succeed after a short prep course. Universal certification means passing Core plus Types I, II, and III.

  • Passing score is typically 70%
  • Core and Type I–III sections; Universal = all three Types
  • Often open-book (varies by proctor/format)
  • EPA 608 is a federal requirement to handle refrigerants and never expires
  • Most students pass after a 1–2 week prep course
What the exam covers

EPA Section 608 tests refrigerant handling, recovery, recycling, and the environmental rules under the Clean Air Act. It is split into a Core section plus Type I (small appliances), Type II (high-pressure), and Type III (low-pressure). Passing all three Types earns Universal certification.

Why most people pass

The questions are knowledge-based rather than tricky, the threshold is about 70%, and many testing formats are open-book for the Type sections. A focused prep course or study guide is usually enough to pass on the first attempt.

Why it matters

EPA 608 is legally required for any technician who buys, handles, or works with regulated refrigerants. It does not expire, employers expect it, and most HVAC programs build the prep — and often the exam — into the curriculum.
