Students are asked to be in attendance every day, all day. Every absence requires a note from the physician or parent/guardian. Every absence counts whether it is excused or unexcused. A high school student must be in attendance for half of every period to be counted present for the class. Tardies to school or to class are only excused with a doctor's note. All other tardies are unexcused. Any time a student is tardy to school the student must sign in to school at the main office in A building. Anytime a student has been absent from school the student must present the absence note to the main office and receive a return to class note for the absence.
