In accordance with the Americans with Disabilities Act (ADA), the Americans with Disabilities Act as amended in 2008, and Section 504 of the Rehabilitation Act of 1973, the College ensures that its admission requirements are uniformly applied, and that its services, activities, facilities and academic programs are accessible to and usable by all qualified students. The Office of Services for Students with Disabilities (OSSD) implements and coordinates reasonable accommodations and disability-related services to promote full participation of individuals with disabilities in all aspects of life. The Rehabilitation Act defines a disability as an individual who has a physical, mental, or learning disability, which substantially limits one or more major life activity (i.e., seeing, hearing, speaking, walking, sitting, standing, breathing, reading, writing, or performing mathematical calculations, and caring for oneself); or who has a record of such impairment; or who is regarded as having such impairment. Both the impairment and the limitation of a major life activity must be established to be eligible under the ADA. Please click here for more information.

6 Other Grading Information FN GRADE - FAILURE FOR NON-ATTENDANCE A Failure for Non-Attendance (FN) grade indicates that a student has failed a course due to nonattendance. It is calculated as an F in the student s grade point average. For students receiving financial aid, failure for non-attendance may require the student to refund to the College all or part of his or her aid. The FN grade will be assigned by the faculty member at any time following the final withdrawal date for the course. See the College s page on Grading policies ( for more information. I GRADE - INCOMPLETE An Incomplete I grade is given very rarely in this course and only for documented, excused absences that result in the student being unable to complete the course on time. The decision to grant an I grade is solely up to Dr. Smith and is reserved for emergency situations (prolonged illness requiring hospitalization would be an example). A contract will be prepared by Dr. Smith that details the student s responsibilities to successfully resolve the I grade. An I grade may impact the student s ability to qualify for financial aid and may result in the student being required to pay back previous student loans. Course Guidelines & Policies ACADEMIC DISHONESTY Academic dishonesty, in any form, has severe consequences. Click here to view FSCJ s academic dishonesty definitions and procedures. LATE MAKEUP WORK Make-up examinations for excused absences must be completed as soon as possible upon returning to school. The student is to confer with Dr. Smith immediately upon returning to school, present documentation for the excused absence, and make arrangements for the make-up exam. Failure to do this may result in forfeiting the right to take the make-up. ATTENDANCE POLICY Due to the unique responsibilities associated with becoming a competent health professional, the progressive nature of the curriculum and its importance to the provision of quality oral health services, attendance and class participation is required at all scheduled clinics, laboratories, seminars, case presentations, scheduled classes and individual faculty appointments. Should an absence be necessary, the student must contact the course instructor prior to the start of class. Failure to communicate in the above manner will result in the absence being considered unexcused. Only an excused absence (student illness with physician documentation, accident, death in the immediate family, jury duty or any deemed excusable by the course instructor) may be made up. A note from a physician or other appropriate individual must be submitted immediately upon returning to campus. Failure to do so will constitute an unexcused absence. An unexcused absence will result in a grade penalty of a 2-point reduction from the final grade for the first absence. Further unexcused absences will result in a 5-point reduction from the final grade for each incident. Make-up exams for unexcused absences will not be provided. In this case, a grade of zero will be given for the assignment. Late arrivals to class are considered unexcused absences.

7 POLICY ON ELECTRONIC DEVICES Refer to the Electronic Device Policy section of the Student Handbook. Unapproved devices should not be used during class time. Approved devices should be used only for permitted purposes. If seen by instructor, one warning will be given during the term for any infraction and after that points will be deducted from your grade. COMMUNICATION In this course, as in all courses in FSCJ s Dental Hygiene program, each student is expected to present themselves professionally in their actions, attitudes, dress, and written/verbal communication. All written assignments will be evaluated for professional language, grammar and spelling. No handwritten assignments will be accepted in this course. Students should check their FSCJ daily as faculty post course related information via this link. Failure to do so may result in missing key information. Having not read faculty messages is not an acceptable excuse for failure to respond appropriately. Students may elect to configure a link between their FSCJ and personal addresses to receive messages.
