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).

3. Must be free of all legal issues.
