CEU Requirements: NL-DECThe Newfoundland & Labrador Department of Environment & Conservation (NLDEC) limits the number on continuing education units (CEUs) that may be obtained from online training. For structural certificates, no more than five CEUs may be acquired from online training during each five year period. The NLDEC requires you to spend a minimum of 50 minutes in a course and pass the final quiz with at least 70% correct answers in order to earn CEUs. Print a certificate of completion after the final quiz or at any time from the My Course History link. Keep the certificate for your records as proof of successful completion of a course.
