While the school does not release grades to students (except upon direct request), there is an evaluation and feedback system. At the end of every semester at St. John's, each student comes together with his or her tutors to be evaluated on his or her academic performance. This exercise is called a Don Rag, a term which comes from Oxford, where professors ("dons") would "rag" on their students.citation needed Don Rags begin with each tutor discussing the present student's performance in the third person to the other tutors as if the student were not there. After this, the student is asked if he or she has anything to add, at which point the student may discuss his or her own performance in light of the tutors' comments, although he or she is not required to do so. In junior year, students have the option of choosing to participate in a "conference", in which the student takes up the responsibility of leading a self-evaluative discussion, rather than a Don Rag. In senior year students do not receive Don Rags.
