Student Attendance Policy: 

The LHWHS philosophy is that regular attendance is vital to the success of students. Ladue High School values attendance and punctuality. Students are expected to attend classes daily and to arrive on time. Student should maintain a good attendance record because a direct relationship exists between school attendance and grades, citizenship and overall success in school. Students and parents should understand that absences, whether excused or unexcused, negatively impact student learning and the student's grade in class. Furthermore, the regular interaction on students with one another in the classroom and their participation in well-planned learning activities are necessary parts of the learning process. Absence from school may be necessary under certain conditions, especially for certain chronic illnesses. The school has a compelling interest to ensure that students attend class. 

  • School hours are 7:30am to 2:30pm.
  • Students are expected to arrive at school and to all classes on time. 
  • The attendance policy is calculated and implemented on a semester basis. 

Excusing a Student: 

Parents/guardians are responsible for telephoning the Attendance Office at 993-4540 on the day the student is absent from school. An answering machine is available 24 hours a day to accept calls from parents in advance or on the day of the absence. Telephone requests for early dismissal of a student shall be honored only if the caller can be positively identified as the student’s parent or guardian. Any absence not verified by the parent/ guardian within 48 hours after the student returns to school will count as an unexcused absence. Written messages, including emails, will be accepted, but such messages MUST include a contact telephone number for verification. Any person requesting release of a student must present proper identification prior to release of the student. Students who are 17-years-old and living independently and students 18 years or older must validate their own attendance and dismissal.

LHWHS Student Sign-out Process and Procedure:

    • Parent/guardian email address
  • Student safety is our top priority, and students with a parking permit will not be allowed to leave campus until both forms of permission are received.

  • A student who requests to go to their car during the school day will be given a pass after referencing the parking database and signing-out/in.

  • Sign-in/out sheets and visitor sheets are official student records and must be kept on file for a full school year.

Students Arriving/Returning Late to School: 

Students arriving late to school or returning while school is still in session must sign in at the Attendance Office and receive a pass to class. 


A student is considered tardy when he or she enters the class after the bell has rung. Individual teachers may establish further requirement (e.g., being seated, having materials ready, etc.). Arriving to class more than 40 minutes late without a pass will be considered an unexcused absence. A student who has three (3) tardies to class in a grading period will receive and "I" citizenship grade and parents will be notified. A fourth tardy may result in a "U" citizenship grade, parent contact, student conferences, and after-school detention. 

If a teacher lowers a citizenship grade due to one or more unexcused absences or tardies, teachers will notify parents of the lowered grade.
