You must take refresher training before you apply for recertification to EPA. You should begin looking for available courses well before your current certification expires, because refresher courses may not be available in your area on a frequent basis. However, EPA recommends that you take your refresher training no earlier than 18 months before your current certification expires. You will not lose time from your current certification if you take refresher training early. When you apply for recertification, EPA will issue you a certificate that begins on your current expiration date and expires three years from that date.
If you are unable to find an accredited refresher course in your discipline, you may take an accredited initial course in your discipline. If you choose this option, you must successfully complete the entire course.
