The University of Arizona's policy on Class Attendance, Participation, and Administrative Drops governs expectations around attendance university-wide. You can review the full policy in the UA Course Catalog.
Absences for any sincerely held religious belief, observance, or practice will be accommodated where reasonable. See the UA Religious Accommodation Policy for details.
Absences pre-approved by the UA Dean of Students will be honored. See the UA Attendance Policy for more information.
For CSc 422, there is no required attendance in the sense that I will not take roll. However, daily quizzes will be given at the start of each class — i.e., at 8:00 am sharp. Missing a quiz means a zero for that quiz; there are no make-ups except in extraordinary circumstances pre-approved by the instructor. Consistent attendance is therefore strongly in your interest.
