Apprenticeship
The United Services Military Apprenticeship Program (USMAP) is a formal military training program that provides active duty and Full Time Support (FTS) Army, Navy, Marine Corps, and Coast Guard Service members the opportunity to improve their job skills and to complete their civilian apprenticeship requirements while they are on active duty. The U.S. Department of Labor (DOL) provides the nationally recognized "Certificate of Completion" upon program completion.
USMAP enhances your job skills and shows your motivation for more challenging military assignments. Having a DOL Certificate of Completion is an advantage in getting better civilian jobs since employers know the value of apprenticeships.
Also, your DOL Certificates are part of your Learning and Development Roadmaps (LaDR) — and these certificates will enhance your opportunity for advancement and retention.
The following USMAP apprenticeship trades are related to the EN-Engineman rating:
Completing an apprenticeship is a process with four major steps. Proceed to Step 1 on the USMAP website to select an apprenticeship trade that is related to your military occupation.
If you are interested in pursuing a career as a civilian mariner when you separate from the military, employment in the Maritime Industry as either a civil service mariner (CIVMAR) or as a Merchant Mariner in the shipping industry, you will likely need to attain credentials from the US Coast Guard through the National Maritime Center (NMC). To evaluate your sea service for Merchant Marine credential eligibility, see the MilGears Mil-2-Mariner (M2M) Tool.
Enlisted Active Duty and Reserve US Navy personnel in eligible ratings may have the Transportation Worker Identification Credential (TWIC) fees, application fees, and USCG credentialing exam fees funded through the Navy COOL program. For more detailed information about mariner careers, USCG credentialing requirements, how to apply for USCG credentials, and how to use Navy COOL for funding, review the Blueprint to Mariner document.
The following sections outline the USCG credentialing requirements and processes.
Guidance on Waiver of Merchant Mariner Credential (MMC) Application Fees for Active Duty Members of the Uniformed Services
The Office of Merchant Mariner Credentialing has published CG-MMC Policy Letter 02-20, titled: Guidance on Waiver of Merchant Mariner Credential Application Fees for Active Duty Members of the Uniformed Services.
Active duty members of the uniformed services are eligible for a waiver of fees for evaluation of an application for an MMC, the administration of an examination required for an endorsement, and for the issuance of an MMC. The waiver applies to members of the Army, Navy, Air Force, Marine Corps, Space Force, Coast Guard, and the commissioned corps of the National Oceanic and Atmospheric Administration and the Public Health Service. This policy is available on the Coast Guard Merchant Mariner Credentialing policy website on the MMC Policy Webpage.
Mariners and other interested parties should contact the Mariner Credentialing Program Policy Division at: MMCPolicy@uscg.mil or (202) 372-2357 with any questions or feedback.
Merchant Marine Credentials (MMC) are credentials issued by the United States Coast Guard through the National Maritime Center. In general, there are two types of merchant fleets: those that operate in national waters and those that operate in international waters. The type of credential you need depends on the fleet type. There are several credentials for which you may be eligible depending on your military occupation, training, and experience.
The two general types of credentials issued to US mariners corresponding to the two fleet types are:
National Endorsements
National endorsements can be used for positions including passenger for hire vessels, charter boats, offshore supply vessels, tow boats and domestic operations.
Standards of Training, Certification, and Watchkeeping (STCW)
Standards of Training, Certification, and Watchkeeping (STCW) for Seafarers are internationally recognized endorsements. STCW endorsements grant greater employment flexibility and are highly desired by employers working with large cargo vessels, international tows, tankers, and cruise ships.
Which credential to choose is based on your professional experience and the requirements you meet as well as your professional goals. Small and large vessels are used in both national and STCW operation, so the "best" choice will depend on your personal goals and where you want to work. Depending on your military occupation, training and experience, you can be awarded different credits from the National Maritime Center towards your Merchant Mariner Credential. The two primary categories of credentials you would choose from are:
Engine
Engine means the department aboard a ship responsible for the main propulsion and auxiliary systems, and other mechanical, electrical, hydraulic, and refrigeration systems, including deck machinery and cargo-handling equipment. For more information and topics on the Engine exam contents, see the USCG Engine Reference Library.
Deck
Deck means the department aboard a ship responsible for navigation, cargo, command, and control functions. Deck crew (excluding individuals serving under their officer endorsement) means, as used in 46 U.S.C. 8702, only the following members of the deck department: able seamen, boatswains, and ordinary seamen. For more information and topics on the Deck exam contents, see the USCG Deck Reference Library.
Some Deck functions currently in relatively high demand are highlighted in the Civilian Mariner Careers tab in the Related Occupations section on this page.
To evaluate your sea service for Merchant Marine credential eligibility, see the MilGears Mil-2-Mariner (M2M) Tool.
To determine if your military or civilian training courses have been reviewed and accepted by the USCG National Maritime Center (NMC) for credit towards credentialing standards, review the approved course listings.
Some USCG NMC approved US Navy training is highlighted in this US Navy school report.
The following links provide copies of USCG approval letters that you may include in your application. These training approvals are based on a review of naval training to USCG/STCW endorsements. The approvals may meet USCG/STCW requirements in whole or fulfill a portion of training towards a USCG/STCW endorsement: (Check back often, as this listing of approvals is expected to expand)
Navigation and Vessel Inspection Circulars (NVIC) provide detailed guidance about the enforcement or compliance with a certain federal marine safety regulations and Coast Guard marine safety programs. Click here to learn move about NVICs.
The Navigation and Vessel Inspection Circular (NVIC) assessments listed below are specifically related to training and experience certification of applicants as is required for Standard of Training Certification and Watchkeeping (STCW) credentials. A US Navy E5 or above who is approved by the commanding officer to sign off on equivalent level assessments, i.e. – Navy PQS, may sign off the NVIC STCW assessments for an applicant pursuing STCW credentials.
The STCW NVICs included in this section contain examples of forms showing the PQS and Navy training references in parenthesis for an applicant and the qualified assessor to reference. Below the examples are links to blank NVIC forms that you can print as the official source document, to be initialed and signed by the assessor in the appropriate spaces, and then submitted in the application package to the National Maritime Center.

Each USCG credential has drug testing requirements. See the USCG National Maritime Center website for specific information. Members can also consider individualizing this sample Drug Testing Participation letter which will be acceptable to the National Maritime Center reviewers. If using the Drug Testing Participation letter format, it must be dated within 180-days of the application. Reservists must have been on active duty for at least 60-days of the previous 180-days.
Step 2: Prepare Sea Service Letter
Navy Sailors can use the US Navy Vessel Information document and their own sea service record to complete the sea service letter requirement for inclusion in the application package. Sailors might find it helpful to refer to these blank sample letters or this complete Navy sample letter as they complete their sea service letter.
