Advanced Tactical Training is a special curriculum for Starfleet officers. Officers must be recommended for this training. It is very difficult and challenging, and in many years half the class drops out. (TNG: "Preemptive Strike")
Starfleet Academy midshipmen who excel in tactical disciplines may be recommended to the College by their instructor, in their junior or senior year. The ATTC curriculum for Academy undergraduates takes two years to complete in most cases.
