Upon admission to NPC, a student assumes the responsibility of completing each course for which he or she is registered. The student is expected to attend all sessions of the classes in which he or she is enrolled. Any student who has three absences without excuses acceptable to the instructor, medical or otherwise, may be dropped from the class. Students who miss the first two meetings of the class may also be dropped. After a student has been dropped from the class for unexcused absences, an appeal for reinstatement will be considered only under extenuating circumstances.
