Unless an exemption or extension applies, the failure to comply with the physical exam and immunization requirements by October 15 of the current school year will result in the student's exclusion from school until the required health forms are presented to the District. New students who register after October 15 of the current school year shall have 30 days following registration to comply with the health examination and immunization regulations. If a medical reason prevents a student from receiving a required immunization by October 15, the student must present, by October 15, an immunization schedule and a statement of the medical reasons causing the delay. The schedule and statement of medical reasons must be signed by the physician, advanced practice nurse, physician assistant, or local health department responsible for administering the immunizations.
