Merchant Mariner Credential (MMC)

The MMC contains identification information and specifies the postions onboard a vessel that an individual is qualfied to sail in.  MMA cadets will apply for a Cadet Deck/Engine rating, enabling them to receive a discharge/letter of sea service as "Cadet" or "Cadet Observer" when sailing on qualifying vessels.  Cadets will also apply for the entry-level ratings of Ordinary Seaman (OS), Wiper, and Steward's Department (SD).  These ratings do not require sea time, prior experience, or a test or exam.  All 4C Marine Engine and Marine Transportation students are required to apply for their TWIC, complete VPDSD Training and apply for their cadet Merchant Mariner Credential in their freshman year to be in compliance with MARAD'S Cadet Credential Policy (Maritime Administration).

To be eligible to apply for an MMC, a cadet:
1. Must be a US citizen or an alien lawfully admitted to the US for permanent residence.
2. Must have a Transportation Security Administration Credential (TWIC).   
3. Must be free of all legal issues.
4. Must be able to meet the medical criteria for licensure.

In order to obtain a cadet MMC, cadets must complete the VPDSD course, Vessel Security for Persons with Designated Security Duties.  Cadets are required register for the scheduled date(s) in Self Service and complete the full training to receive a certificate of completion.  This is required for the MMC, commercial shipping and graduation.
