API – Exams (not conducted by IVEPE-SEV)

Taking this course will provide an excellent review of exam requirements and prepare the attendee, in large part, to challenge the API 653 exam (Aboveground Storage Tank Inspector).
Certification, as an inspector to various API programs is done directly by API. The exam can be taken on-line.
