School Hours

The school gates are opened at 7:30 am allowing students to enter the school. Students must then report to their assigned point of assembly until released by the duty teacher at 7:50. The school day commences at 8:10 am and consists of homeroom, recess and lunch, and eight 40 minute periods.

School ends at 3:15 pm (all days except Wednesday) at which time students return home, apart from students participating in after-school activities. School buses depart at 3:25 pm and there is school bus at 4:30 pm for students taking part in after-school activities.

There is a shortened school day on Wednesdays, when classes end at 2:15 pm and buses depart at 2:25 pm. The purpose of the shortened school day is to provide teachers additional time for collaborative meetings. Students follow a compressed schedule of hours on Wednesday, where no lessons are missed.

The Nursery morning program is a half-day program and ends at 12:00 pm, at which time these students return home. There is an optional full day Nursery program for students who are 3 years of age by September 30th of the current academic year. The Pre-Kindergarten class is a full day program.

Only Grade 11 and 12 students are allowed onto campus at 07.30 am for unsupervised private study. Both grades may also stay unsupervised at school until 17:00 pm. Any other student wishing to stay outside of the hours listed above may only do so with explicit teacher supervision and principal approval.

Grade 12 students are also permitted to enter the school campus on weekends or holidays between 08:00 am and 16:00 pm provided that they have teacher permission and principal permission. They must sign in at the school guard house and obey all other rules listed below.

With the exception the above, other students may only remain on or return to the school campus after 15:30 pm for after-school activities or other official events, and they must then be under the direct supervision and responsibility of a teacher. They must leave the campus immediately after the activity or event in question is finished. Student wishing to be spectators at IST hosted sports events may do so only with the permission and under the supervision of attending IST coaches and teaching staff.

Any student who will be on campus outside of normal school must sign their name in the On Campus Log Book located at the reception desk. This log requires that they identify their name and grade and also the location where they will be found in the building. Such students are only permitted to make use of that location and the nearest restroom facilities unless or until such time as proper teacher supervision is also present.

Furthermore, any student wishing to arrive early or stay late must be in possession of his/her ID card at all times, and any staff member may ask the student to produce this card. Students without this card may be asked to leave immediately. Disciplinary consequences will apply for the violation of any of the above rules.


When a student is absent from school, parents are required to telephone the teacher an explanation on the day of absence or provide a written explanation upon the student’s return to class. This written explanation is necessary for proper attendance record keeping. If a child will be absent for a prolonged period, the parents should contact the school office so that the teacher may be informed and arrangements may be made for missed work. A doctor’s note is required following an absence of six or more consecutive school days due to a major illness, communicable disease, or injury. The doctor’s note should state that the student may return to class, as well as noting if there are any physical restrictions.

It is important that students arrive at school on time. Tardiness disrupts classroom activities and may result in a student missing critical learning and affect his/her grades. A tardy student must check in at the front desk in the main lobby to obtain a tardy slip before going to his/her classroom.
