Participation in lectures, discussions, and other activities is an essential part of the instructional process. Students are expected to attend class regularly; those who are compelled to miss class meetings should inform their instructors of the reasons for absences. Faculty often include classroom participation and attendance in student grading and evaluation. In such cases, the instructor will clearly communicate attendance/participation expectations and how this is weighted in terms of grading (for example, the penalty, if any, for an unauthorized absence from class) in the course syllabus. Students who expect to miss several class sessions for personal, professional, religious, or other reasons should meet with their faculty adviser to consider alternative courses prior to registration.
