[[Preston Cole]] was among the first admirals to institute it.<ref name="ImpossibleLife"/>

The curriculum of the Officer Candidate School is diverse between schools. An OCS curriculum is generally open-minded, allowing cadets to choice between the several different military branches in the [[United Nations Space Command]] armed forces.<ref>'''[[Halo 4: Forward Unto Dawn]]''' ''Part 1''</ref> The time a cadet serves at a school generally lasts four years and includes classroom instruction and field exercises on military science, physical training, and leadership.{{Ref/Reuse|for38}}<ref>'''[[Halo 4: Forward Unto Dawn: Squad]]'''</ref><ref name="ImpossibleLife">'''[[Halo: Evolutions - Essential Tales of the Halo Universe]]''', "[[The Impossible Life and the Possible Death of Preston J. Cole]]", ''page 430''</ref> Although generally meant for any military-capable civilian, some academies featured blatant nepotism. The [[Corbulo Academy of Military Science|Corbulo Academy]] was based around the concept of training the offspring of high-ranked military and government officials as commissioned officers.<ref>'''Halo 4: Forward Unto Dawn''', ''Part 3''</ref> Some critics suspected that nepotism was the reason that [[Miranda Keyes]] excelled at her OCS at a young age, due to [[Jacob Keyes|her father's]] respected status in the UNSC and former teaching position at her academy.{{Ref/Reuse|news}}
