Supply officer (Royal Navy) scheme (entering Britannia Royal Naval College (BRNC), Dartmouth, Devon, as a Cadet or Midshipman, under terms similar to those direct from civilian life) was open to those supply branch ratings under the age of about 25. Such ratings were called CW candidates, and they were specially reported on for selection to attend the Admiralty Interview Board before final selection for promotion and entry to BRNC. The second avenue of promotion from rating to commissioned officer was to the Special Duties (SD) List. Petty officers and chief petty officers could, with the approval of their commanding officer, become a CW candidate
Royal Swedish Naval Staff College added. Only the coastal artillery course included physics. In higher education courses, special subjects were included, and in some of the general course subjects. In 1926 there were teachers in 18 subjects. As students, the Navy's subaltern officers were commanded in turn; an entry qualification was not needed. The Royal Swedish Naval Staff College was discontinued in 1961 and the Royal Swedish Armed Forces Staff College was formed by merging war colleges of the different military branches, namely the Royal Swedish Army Staff College (established 1878), the Royal Swedish Naval Staff College (established 1898) and the Royal Swedish Air Force
