Officers and Masters must pass formal examinations to demonstrate their knowledge at various levels, in accordance with national laws and the [[STCW Convention]]. These examinations have a progression based on the size and complexity of the ship, including its sailing area as well as by rank. Globally, most seafarers are required to possess a basic seamanship certificate. In the U.S., the progression begins with what is known as "the six pack", a license that allows fishing guides to operate with up to six passengers . In the [[United Kingdom]], all seafarers, both deck officers and crew, must complete an Efficient Deck Hand (EDH Course) at an approved training provider under direction of the UK [[Merchant Navy Training Board]].<ref>{{cite web |url=https://www.witherbyseamanship.com/course-criteria-for-efficient-deck-hand.html |title=Course Criteria for Efficient Deck |website=Witherby Publishing Group |access-date=19 April 2021}}</ref><ref>{{cite web |url=https://www.gov.uk/guidance/apply-for-navigationalengine-room-ratings-certificate |title=Apply for Navigational/Engine Room Rating Certificate |website=UK Gov |date=13 November 2017 |access-date=19 April 2021}}</ref>

The crew of a large ship will typically be organized into "divisions" or "departments", each with its own specialty. For example, the deck department is responsible for navigation, ship handling and general maintenance, while the engineering division are responsible for propulsion and other mechanical systems. Crew start on the most basic duties and as they gain experience and expertise advance within their area. Crew who have gained proficiency become "able seamen", "petty officers", "rated", or "mates" depending on the ship type and organisation. 

On smaller commercial craft, there is little or no specialisation. Deck crew perform all boat handling functions. The officers of the ship are responsible for navigation, communication, and watch supervision.
