The information is presented exactly as in the H&W ledgers - by the Apprenticeship Trade, then by the name of the apprentice, the day, Month and Year in which he started and then the month and year in which he finished his apprenticeship.
Sometimes apprentices completed their 4 or 5 year apprenticeship early if they demonstrated particular skills or aptitude. Some ended their apprenticeship early because they moved to a different trade within the company and, where detailed, this transfer has been denoted. Some left shipbuilding to take up another trade or occupation, or, as happened during World War 1, left to join the Army or other military services. (Where the original ledgers identify apprentices leaving to “join up” during WW1 this has been shown on the listings).
