During the first seven weeks of training, officer cadets learn militarisation and sea sense, focusing on learning about the military environment, along with team and leadership skills. During the second seven weeks, officer cadets learn essential sea officer skills, including navigation and the marine environment, strategic studies, and basic sea survival. During the second term officer cadets spend 6 weeks in Initial Sea Time (IST), serving aboard capital warships as junior ratings. Upon completion of Initial Sea Time, officer cadets return to Dartmouth for four weeks to complete their final leadership assessment, the Maritime Leadership Exercise (MARL). MARL may be completed prior to IST depending on scheduling. If they have been successful, officers of all branches then pass out of the college.
