EPA 608 Exam Requirements

Eligibility

There are no age, education or experience requirements. Anyone can sit for the exam.

Format

• Closed-book, multiple choice. Each section has 25 questions; you must answer 18 correctly (72%) on each section you attempt.
• Core is required for every type. You can take Type I, II and III in one sitting (Universal) or add types later.
• Type I may be offered as an open-book, non-proctored exam by some organizations. Type II, Type III and Universal must be proctored, either in person or through online proctoring.
• Exams are administered by EPA-approved certifying organizations such as ESCO Institute, RSES, Mainstream Engineering and HVAC Excellence. Fees vary by provider, typically in the range of $20–$150.

Certification

• Certification is issued as a wallet card by the certifying organization.
• It never expires and is valid in every U.S. state and territory.
• If you fail one type section you keep credit for the sections you passed and retake only the failed one.
• Passing is 18 of 25 correct (72%) per section, not an overall average. Details: EPA 608 passing score.

Always confirm current fees, seating time and online-proctor rules with the organization that will print your card. EPA publishes the list of approved programs.
