Academic Integrity

The university has a published policy on academic integrity that may be found at


Attendance Policy

Students are expected to attend every class session of each course in which they are enrolled and to be on time. An instructor has the right to drop a student from a course for excessive absence. Students are advised to determine the instructor’s policy at the first class session. They should note that an instructor may treat lateness as equivalent to absence. (No distinction is made between excused and unexcused absences.) Each instructor retains the right to establish his or her own policy, but students should be guided by the following general College policy: In courses designated as clinical, performance, laboratory or field work courses, the limit on absences is established by the individual instructor. For all other courses, the number of hours absent may not exceed twice the number of contact hours the course meets per week. When a student is dropped for excessive absence, the Registrar will enter the grade of WU.


Courtesy Policy

Eating, drinking, or use of unauthorized hand held electronic equipment is not allowed in the classroom.
