Once you successfully complete a boating safety education course, the certification card you receive is permanent and does not have an expiration date. The necessity to retake the course would only arise if there were changes in state law by the legislature that mandate a renewal or re-certification.
Should you misplace or damage your certification card, please refer to the section titled "How To Replace a Lost or Damaged Boater Education Card." Here, you'll find comprehensive steps to request a replacement for your card.
