The Recruiting Test is the same for Officers & Other Ranks, relevant scores listed in BR3 above.
The RN refers to those promoted from the lower deck to become officers as Upper Yardmen. Those aged over 30 years of age are known as Senior Upper Yardmen (SUY) and will have several years of relevant naval experience plus 4 GCSE's including maths & English. In recognition of this they receive a bespoke package of Naval General Training for 7 weeks intended to build upon the skills and knowledge they have acquired during their careers, thus avoiding repetition in areas in which they are already competent. For those aged under 30 years, known as Upper Yardmen they will join Initial Officer Training and conduct the full 28 week package. Upper Yardmen need a minimum of 5 GCSE's including maths & English, grades A*-C.
