(EPA certification is optional and 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 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.)
