III. CLASSROOM AND ACADEMIC RESPONSIBILITIES

A. Conduct of Classes

3. Attendance: Students are expected to make full use of their educational opportunities by  regular class attendance and to assume the academic risk of absences. An instructor, however,  may set such standards of attendance as he or she feels are necessary for the satisfactory conduct  of a given course. It is the responsibility of students to meet those standards, and of the  instructor to determine whether absences may be excused. Classes, rehearsals, and performances  are generally not held on Yom Kippur and the previous evening.

The General Faculty has approved the following regulations: 

i) Students wishing to observe recognized religious holidays are excused automatically from classes that occur on these dates. 
ii) Faculty are to make it possible for students observing recognized holidays to make up any work they miss, provided arrangements have been made in advance.
