Start Practice TestCommon questions about EPA 608 Core certification
The Core section contains 50 questions. You'll need to score at least 70% (35 correct answers) to pass. However, we recommend aiming for 80%+ to ensure thorough preparation.
You typically have 1 hour to complete the Core section. Our timed practice tests help you build the speed and confidence to finish with time to spare.
Yes, the Core section is identical for all certification levels (Type I, Type II, Type III, and Universal). The difference comes in the additional type-specific questions you answer afterward.
No, the Core section must be taken along with at least one other category. You cannot receive certification for Core alone. Most technicians take Core plus one type or the Universal combination.
If you fail the Core section, you won't pass that specific exam attempt. You can retake the exam, but you'll need to pay the testing fee again. Our practice tests help ensure you pass the first time.
Calculators are not typically needed for the Core section. The questions focus on concepts, regulations, and procedures rather than complex calculations. However, for some Type-specific sections, a basic calculator may be helpful.
