(EPA certification requires the attendee to pass a test administered by the instructor at the end of the seminar. While every attempt is made to provide our attendees with a high quality education, Lewellyn Technology does not guarantee that all attendees will pass this test. It is highly recommended that attendees study on their own in addition to taking these seminars.)
