New Trier High School is committed to forming a partnership with parents/guardians to maintain consistent student attendance.  Regular school attendance leads to high academic achievement and strengthens students’ punctuality, self-discipline, and personal responsibility.  Therefore, the district has established a clear attendance system.  This system will aim to support students while also holding them accountable for regular attendance for all scheduled class periods, including adviser period.   

Reporting an Absence 

Only Parents/Guardians are authorized to report a student absence. Absence reporting is done via Parent PowerSchool platform. Do not divulge your parent login and password to students. Students found entering their own attendance excusals will be subject to disciplinary consequences. 

Report an Absence

Directions for Reporting an Absence in PowerSchool: 

• Select "Attendance Monitor" (bottom of the left side navigation bar). 
• Click on "Report New Attendance." 
• Enter the required information, including an explanation
• Click “Submit.”

Parents/guardians can report an absence through PowerSchool only on the date of the absence or for future planned absences. After the date of the absence, a parent will need to contact the Attendance Office at 847-784-2286 and leave a message with the absence information.

Please note that when submitting an “Report New Attendance” form in the PowerSchool Parent Portal you are requesting the absence be excused by the school. In order to comply with State of Illinois law, the school reserves the right to determine if an absence is unexcused and/or constitutes truancy.

Any absence not corrected within 48 hours will result in the student being subject to academic and disciplinary consequences.

Student Attendance 

Students are required by State law to attend each day school is in session. The Board of Education’s attendance policy states that students will attend and be on time for class on a regular basis. Student attendance is not optional; it is a requirement of every class, including adviser period. New Trier High School students and families are responsible for knowing and following the attendance plan and procedures.
