Attendance Office

To report a student’s absence, notify the school of a late arrive, or have a student leave early, a parent/guardian needs to call the Glenbrook South High School attendance line: 

Starting in the 2022-23 school year, families can report student attendance through the PowerSchool Portal. The system allows families to report a daily absence as well as any future dates a student will not be at school. Reporting an absence can be completed in five easy steps: 

  1. Log into your PowerSchool Portal
  2. Select "Attendance Monitor" from the left navigation pane
  3. Click "Report New Attendance"
  4. Enter details about the absence
  5. Click Submit

Additional details on completing this process are available through on the Reporting Absences in PowerSchool knowledge base article

Student Illness

  • If a student tests positive for COVID, the student should remain home and a parent/guardian should notify the attendance office. The information will be shared with the nurse’s office and someone will be in touch regarding next steps.
  • Students experiencing any flu symptoms are encouraged to remain home. Any tests, quizzes and projects can be made up when they have recovered and returned to school.

Arriving Late or Leaving Early Process

  • Students who are called out during the school day will need to come to the attendance window for a pass and sign out at the time they are leaving the school.
  • Students who are returning to school or coming in late will need to come to the attendance window for a pass and sign in when they enter the school. 
  • Students who fail to sign in or out will receive an unexcused absence for the classes that they missed.
  • Students excused from school must leave the building.
