About the EPA 608 Universal Exam
The EPA Section 608 Universal certification authorizes technicians to service all stationary refrigeration and air-conditioning equipment. It combines a Core section with Type I (small appliances), Type II (medium- through very-high-pressure), and Type III (low-pressure) sections, for 100 multiple-choice questions, and requires 70% on each closed-book, proctored section to pass. The certification does not expire.
Exam sponsor: U.S. Environmental Protection Agency (EPA) via approved certifying organizations. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
100 multiple-choice questions: 25 each for Core, Type I, Type II, and Type III. Universal requires passing all four as closed-book, proctored tests, either in one sitting or by combining separately passed proctored sections; an open-book Core can never be carried into Universal. This practice bank mirrors the four-section structure.
