State Licenses

Some states have specific licensing requirements for the following related civilian occupations. These state licenses may require additional education, training or experience. Click on the occupation below to get more information on state requirements from the U.S. Department of Labor.

For more supervisory and managerial occupations, please refer to the Leader (All enlisted E-4 and above) page.

COOL may be able to assist with funding state licensure on a case by case basis. The following conditions should apply:

Navy Reservists (SELRES) may get a state license funded based on their Navy or civilian occupation, earned academic degree or a semester course. The state license must have relevancy to a Navy occupation or collateral duty.
Service members may get a state/county or municipality certification/license funded if they are separating or retiring in the state in which they desire the license. This will be a onetime funding opportunity based on their Navy or civilian occupation, earned academic degree or a semester course. Renewals are authorized 60 days prior to their discharge/separation. The license must have relevancy to a Navy occupation or collateral duty. Service members should make contact with Navy COOL prior to 18 months remaining on their soft/hard EAOS due to the complicated funding processes of some states. Certification/license must be completed 60 days prior to separation.
For each of the above opportunities, the Service member must contact Navy COOL prior to submitting a voucher request for licensure funding coordination.

As with any state license, you must meet all state eligibility criteria. Funding of a state license must have relevancy to a Navy occupation or collateral duty (e.g. no real estate license, no beautician license, no private eye license, etc…). Contact Navy COOL for more information.

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.

USCG (NMC) Credentialing

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.

Waiver of Merchant Mariner Credential Application Fees for Active Duty Members

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 Credentialing Basics

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 Is Right For You?

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.

Military Training Approved By USCG (NMC)

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)

NVIC Assessments

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.

For detailed information about mariner careers, United States Coast Guard (USCG) credentialing requirements, and how to apply for USCG credentials through the National Maritime Center (NMC), U.S. Navy personnel can review the Blueprint to Mariner document to learn about funding opportunties. U.S. Army personnel should contact the U.S. Army Transportation School, Maritime and Intermodal Training Department (MQD) in Buildling 461, Ft Eustis, VA or call 757-878-6337 for more information.

For personalized information on Merchant Mariner credentials that may be attainable or nearly attainable based on your specific military experience and how to navigate the process, visit the Mil-2-Mariner (M2M) Tool on the MilGears website. The M2M Tool analyzes your entries and uploaded service records for creditable sea service, training and assessments that you completed during your military service and compares your results against the standard for an original or upgraded Merchant Mariner Credential to determine which credentials you may be able to pursue based on your specific military experience.

Direct-Hire Authority for Advancing Military to Mariner with the Department of Defense

The Under Secretary of Defense for Personnel and Readiness signed a memorandum on 8 October 2020 providing and delegating to military departments, agencies, and field activities, direct-hire authority to employ qualified separated members of the uniformed Services with valid merchant mariner licenses or sea service experience in support of United States national maritime needs.

This direct-hire authority enables the DoD to recruit and appoint separated members of the uniformed Services who are qualified candidates without applying competitive rating and ranking procedures. Qualified candidates are individuals who:

Possess a valid USCG Merchant Marine Credential
Meet the minimum standards for the position as published
Meet any selection placement factors and/or competencies identified as necessary for appointment to the position

Service members may be directly selected without a competitive job interview process. For more information see the Direct-Hire Authority for Advancing Military to Mariner within the DoD document.

For more information about Federal direct-hire policy, data, and oversight, please refer to the Office of Personnel Management (OPM) Hiring Information web page.

To evaluate your sea service for Merchant Marine credential eligibility, see the MilGears Mil-2-Mariner Tool.

Military Sealift Command (MSC)

One way to continue your service to your nation is through the US Navy’s Military Sealift Command (MSC). As an MSC civil service mariner, you join the premier provider of ocean transportation for the Department of Defense which operates over 100 non-combatant, civilian-crewed ships in support of the US Navy, deployed US forces, and coalition partners around the world. Learn more about Military Sealift Command at the "About MSC" page on their website. You can see which MSC occupations most closely relate to your military occupation in the MSC tab in the Related Occupations section on this page.

Merchant Marine Industry

Another way to serve as a civilian mariner outside of government service is as a US Merchant Marine. The merchant mariner industry consists of privately-owned, US registered merchant ships and a variety of towing, offshore supply, and passenger vessels which provide waterborne transportation for passengers and cargoes moving in domestic and international commerce. Primary shipboard employment categories include deep sea, Great Lakes, towing and barges, inland and coastal waters, passenger vessels, and offshore and mineral operations. Other areas of employment in the maritime industry include shipbuilding and repair, longshoring (cargo handling), port terminal administration, and intermodal logistics.

General information about the maritime industry can be found in the Maritime Careers Brochure and the Maritime Careers Resources Guide. The Maritime Industry website also includes numerous informative links to maritime companies, schools, and seaports.
