To help employers ensure compliance, ISF has updated its widely used On Board Training Record Book for Deck Cadets (Trainee Officers), to take account of the amended competence requirements in STCW 2010, which entered into force in January 2012. The revised ISF Book takes full account of the competence standards stipulated by STCW 2010, such as the use of Electronic Chart Display and Information Systems (ECDIS), application of leadership and team working skills and proactive measures to protect the marine environment. The training tasks included have been developed to ensure that cadets make the best use of their seagoing service, and to help supervising officers make an objective evaluation of whether cadets are competent.
