In Ranger School, you are constantly being assessed by the cadre, known as Ranger Instructors or RIs. Ranger School consists of three phases: Benning Phase, Mountain Phase, and Florida Phase. If you are given a poor score by the RIs, you will not proceed to the next phase and will be "recycled", or sent back to the beginning of the phase you were in. If they give you a bad enough score, you will be completely dropped from the course. "Recycling" is fairly common, and some students have been know to do it as many as three times before passing.
