sometimes within another platoon, in order to ensure that this was not the reason the student was peered. If it happens within this new squad, however, this is taken as an indication that student is being singled out because they are either lazy, incompetent, or cannot keep up. At this time the student will usually be removed from the course. Recycling If a student performs successfully, but suffers an injury that keeps them from finishing, they may be medically recycled (med recycle) at the discretion of either the battalion or the Ranger Training Brigade commander; the student will be given an opportunity to heal and finish the course with the next class. Students recycled in the first phase are temporarily assigned to Vaughn's Platoon (informally known as the "Gulag" to Ranger students). Recycled students typically receive classes on Ranger School tasks and perform a variety of general tasks for their respective Ranger Training Battalion. While marking time at Ranger School is not always pleasant, those who have been recycled typically perform well when reinserted back into the course, with pass rates well over 80%. Students can also be recycled for a variety of other reasons, including failing their patrol evaluations, peer evaluation, collecting 3 or more bad spot reports in a phase, or receiving a Serious Observation Report (SOR). Students may receive SORs for actions including, but not limited to, negligent discharges, safety violations involving demolitions or mountaineering, not looking through their sights while firing, or throwing away ammunition to lighten their load while on patrol. If a student fails a phase twice for the same reason (patrols, peers, etc.) they will usually be dropped from the course, but may possibly be offered a "day one restart," and will restart on Day 1 of the next Ranger School class. In rare cases, those assessed of honor violations (lying, cheating, stealing) and SORs may be offered a day one restart as opposed to being dropped from the course. Graduation rates Historically, the graduation rate has been around 50%, but this has fluctuated. In the period prior to 1980, the Ranger School attrition rate was over 65%. 64% of Ranger School class 10–80 graduated. The graduation rate has dropped below 50% in recent years: 52% in 2005, 54% in 2006, 56% in 2007, 49% in 2008, 46% in 2009, 43% in 2010, and 42% in 2011. Recycles are included in the graduation
