Exclusion of Students for Health Reasons
A state school's principal who believes on reasonable grounds that a student is not clean enough to keep attending school, or that the student may have a communicable disease may preclude the student from attending school. Immediately after precluding a student, the principal must make all reasonable efforts to inform the school's board of trustees, the student, or the student's parents if the student is under 20 years of age, that the student has been precluded and the reasons for the preclusion. The Medical Officer of Health must be informed if the preclusion is because of a communicable disease. The board is required to look into the matter and must either cancel or confirm the principal's decision. If the decision is confirmed the student must not attend school until the principal is satisfied that the student is clean enough, or in the case of a communicable disease, until the board receives a medical certificate stating that the student is clean enough to return to school.
Obviously, exclusion because of a communicable disease can be a defence to a charge of not attending school.
