Mariners who wish to serve as a DE or QA should send an e-mail request to Alternatively, submissions can be mailed to:

The documentary evidence necessary to become a QA is listed in 46 CFR 10.405. Additional guidance is found in NVIC 19-14, Enclosure 1, on how to obtain approval as a QA. Enclosure 2 provides guidance on professional qualification criteria for assessors for various STCW endorsements.
