Yes, the USCG reports that MMCs are now being endorsed with all STCW endorsements for which the mariner is qualified. Until December 31, 2016, these endorsements will be automatically included at renewal if you have 12 months of sea service in the last five years. After that date, mariners must demonstrate continued competence through the appropriate combination of sea service and training. In addition, in order for your Chief Engineer STCW endorsement to be valid after December 31, 2016, you will need to complete training in leadership and managerial skills, engine resource management, and management of electrical and electronic control equipment.

The USCG reports that the course completion certificates for these three courses are valid for 5 years.

Leading up to 1/1/2017, the USCG will accept assessment signed by mariners that hold an appropriate national endorsement equal to, or superior to, the relevant level of knowledge, skills, and abilities being assessed.  After 1/1/2017, a Qualified Assessor must witness the demonstration of competency.

The term "Qualified Assessor" (QA) is defined in 46 CFR 10.107 as “a person who is qualified to evaluate, for STCW endorsements, whether an applicant has demonstrated the level of competence in the task for which the assessment is being made. This person must be individually approved by the Coast Guard or through a Coast Guard approved or accepted course or program of training.” CMES is developing a QA Course and will submit it to the USCG for review.

NVICs 15-14 and 10-14 include a Records of Assessment for 3rd and 2nd Assistant Engineers or 3rd mate/2nd Mates trying to qualify for Management-level STCW Endorsements.  These assessments can be performed on a ship or as part of a USCG-approved course.  For the Mates, most of CMES’ Deck Officers courses include the Assessments continuing from USCG Policy Letter 04-02 as part of the evaluation process; however, a few Assessments must still be performed shipboard.
