The following policies are of particular interest: Academic Honesty The university is committed to high standards of academic honesty. Students will be held responsible for violations of these standards. Please refer to the university’s academic honesty policies for a definition of academic dishonesty and potential disciplinary actions associated with it. Drops and Withdrawals Please be aware that, should you choose to drop or withdraw from this course, the date on which you notify the university of your decision will determine the amount of tuition refund you receive. Please refer to the university policies on drops and withdrawals (published elsewhere) to find out what the deadlines are for dropping a course with a full refund and for withdrawing from a course with a partial refund. Special Services If you have registered as a student with a documented disability and are entitled to classroom or testing accommodations, please inform the instructor at the beginning of the course of the accommodations you will require in this class so that these can be provided. Disturbances Since every student is entitled to full participation in class without interruption, disruption of class by inconsiderate behavior is not acceptable. Students are expected to treat the instructor and other students with dignity and respect, especially in cases where a diversity of opinion arises. Students who engage in disruptive behavior are subject to disciplinary action, including removal from the course.

Course Policies

Incoming Competency Expected By Instructor Students should should have successfully completed requisite B. The student notify the instructor priorthe to class if an 5000-level absence is anticipated and he/she should not miss more than four contact hours. Makeup work will be assigned and if the absence is unexpected, it may exceed the material presented. C. For absences of eight hours, the instructor has the option to lower the student's grade one latter grade and to inform the student of the action. D. If the student is absent twelve hours or more, the instructor has the option to assign a grade of “F” (work that is unsatisfactory) and to inform the student of the action. It is the student's responsibility to withdraw from the course. E. For excused absences (in an extreme case) when the instructor chooses to award a grade of I (Incomplete) for twelve to sixteen hours missed,

the student must provide acceptable documentation to verify that the absences were unavoidable (e.g., illness, military duty TDY). These actions will be coordinated with the site director who will ensure that the documentation is placed in the student’s file. F.

In all cases, without excused absences, the student should withdraw from the course if he or she has more than sixteen hours of absences.
