The teacher marks the student as present, absent, or tardy. The campus administration determines if the absences are excused, unexcused, etc. A student's attendance record may be changed by the teacher or by campus administrators. Some circumstances in which this may occur include:

• A student was marked absent and then arrived to class tardy
• An absence was marked unexcused but was later determined to be excused
• An absence was marked excused but was later determined to be unexcused

It is the teacher's responsibility to record attendance in a timely manner (at least daily). If this occurs, the attendance record will be updated throughout the day, and the most accurate attendance data will be displayed on the student's attendance page.

The official attendance record determines funding received by the campus from the state. Each campus is required to maintain records showing Average Daily Attendance (ADA) for the campus. The official attendance for the day is taken during the ADA period (usually the second or fifth period of the day).

• The established ADA period does not change during the school year.
• For funding purposes, students who are absent during the ADA period will be counted absent for the entire day. Students who are present during the ADA period will be counted present for the entire day.
• For funding purposes, a student must be present for at least two hours to be considered in membership for a half day, and for at least four hours to be considered in membership for one full day.
