The International Fleet Pre-Command Schools consisted of four institutions; Tactical, Navigational, Combat, and Support. After graduating from Battle School, one would go to one of these schools. If one was chosen to go to either Tactical or Support School, they would stay there for three years before heading on to Command School.
Tactical School Edit
Tactical School was at an unknown location in space where students who showed extra talent or initiative in Battle School were sent for additional training prior to going to Command School. Normally, students would stay there for three years before graduating. However, Bean and several other members of Ender Wiggin's Dragon Army traveled to Tactical School on the Condor and attended there for one week before being sent to aid Ender at Command School.
Navigational School was a training center sponsored by the International Fleet.
Combat School Edit
Combat School was a training center sponsored by the International Fleet. It was where graduates of Battle School went if they were not qualified for Command or Tactical School.
Support School Edit
Support School was a training center sponsored by the International Fleet. Students would spend three years at the school before graduating to Command School.
