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.

Petty officers and chief petty officers could, with the approval of their commanding officer, become a CW candidate
Royal Naval College of Canada building was heavily damaged in the 1917 Halifax Explosion. In the Spring of 1918, the college was temporarily moved to facilities at the Royal Military College (RMC) in Kingston, Ontario. In September, the college was relocated to the naval dockyard at Esquimalt, British Columbia. The college was closed in 1922 after a parliamentary decision. The King’s permission was obtained to add the prefix 'Royal' to the title of the Naval College of Canada in October 1910, with the abbreviation being 'R.N.C.C.' The naval college was established at Halifax, Nova Scotia in 1911. RNCC was co-commanded by Lieutenant Commander Edward Atcherley
