ATTENDANCE POLICY:
No absences are allowed in any dental hygiene class/lab unless the student is hospitalized or if there has been a death in the immediate family. Arrangements must be made that do not conflict with class times for doctor’s appointments, sick family members, and transportation needs. In cases of emergency or illness, it is suggested that the student contact the instructor prior to class (or clinic) should an absence be anticipated. Class handouts can be obtained from the instructor. Class notes can be obtained from classmates. One point will be deducted from the final average for each unexcused absence and ¼ point for each tardy; 4 tardies will equal 1 absence.
Physically absent is considered if 15 minutes late for class or
laboratory session. Calling prior to class does not result in an
“excused” absence, but rather assists the faculty in evaluating the student’s progress in professionalism. If you are not present, you are not learning the information or putting in the necessary time to develop your skills. You will receive an attendance notice every time you are tardy or absent from class. See Dental Hygiene Handbook for additional stipulations.
MAKE-UP POLICY: The student will not be able to make up exams without a doctor’s note and/or at the instructor’s discretion. The student will receive a “0” for that exam or quiz. If a make-up is given, the make-up exam will be different from the one given at the
scheduled time.
