EPA Section 608 Technician Certification
Section 608 of the Clean Air Act requires technicians who maintain, service, repair, or dispose of stationary equipment containing covered refrigerants to pass an EPA-approved test.
This learning path covers what the rule requires, which certification type matches a given piece of equipment, and the core safety and recovery practices the test topics emphasize. It is a study resource, not the certification exam.

How EPA 608 certification works
EPA Section 608 certification is required for technicians whose work can release regulated refrigerants from covered stationary refrigeration and air-conditioning equipment. To earn the credential, a learner must pass an EPA-approved test administered by an EPA-approved certifying organization. The credential does not expire.
Choose the equipment scope
Match the work to Type I, Type II, Type III, or Universal certification.
Prepare for the EPA 608 test
Use the EPA 608 study guide and EPA 608 test practice to review the published topics.
Test with an approved organization
Confirm current testing options directly in the EPA list of approved certification programs.
Official basis: EPA Section 608 Technician Certification.
Can you get EPA 608 certification online?
Some EPA-approved certification programs offer remote or online testing that does not require travel to a physical testing location. Options vary by provider, and the test still must be administered through an EPA-approved certifying organization. Skills Exam Prep is an independent study site: it does not administer the test or issue EPA certification.
Use the current EPA certification-program directory to verify remote-testing availability, provider approval, and registration details before paying or scheduling.
EPA 608 Universal certification
Universal certification covers all three equipment groups: Type I small appliances, Type II high- and very-high-pressure appliances, and Type III low-pressure appliances. EPA states that the Core test used for Universal certification must be proctored; an open-book Core result cannot be used to earn Universal.
