Certification boundary
This site provides independent educational organization of public information. Only an EPA-approved certifying organization can administer a valid Section 608 certification test and issue the credential.
Practice boundary
Practice questions are original and do not reproduce the protected EPA test bank. A practice score is not certification and does not guarantee a real-exam result.
Regulatory and employment boundary
Rules, provider details, state licensing, local permits, and employer requirements may change. Confirm final decisions with EPA, the current eCFR, the chosen approved certifier, and relevant state or local authorities.
