School generally commences on or before August 13th of each year. New student/parent orientation for MS and HS are scheduled the day before school opens. School usually ends after the first week in June of each year. You will find that the ISB calendar consists of the same number of instructional days as US schools. Please check the ISB Calendar for the most up-to-date information.

Each bus is air-conditioned, has retractable seat belts, and a bus supervisor. Service is door-to-door for all students before school and immediately after school at 2:20pm. There is an Elementary after-school activity bus at 3:50pm which also offers door-to-door service for students in grades Kg – 5. Middle School and High School students also have additional 3:50pm and 5:10pm bus services that travel on the main routes. Students will be dropped off on a main route at a point closest to their home. For many students, this means a short walk into a Soi (lane).

ISB has uniforms for sale at the ISB Book Store on our campus. The uniform consists of a polo shirt with the school emblem with either khaki or black shorts, pants, or skirt. Physical Education (PE) uniforms are required at all levels. This is a unisex uniform that consists of black knit shorts and a gray ISB T-shirt. Elementary School students wear the PE uniforms to school on the day they have PE classes. Middle School and High School students change into their PE uniforms before PE class in the locker rooms provided.

A great deal of effort is invested in creating balanced classrooms in order to provide for the most effective instruction. We try to balance each Elementary School and Middle School classroom in terms of gender, nationality, language proficiency, academic ability, and maturity level. Parents may complete a class placement form, available in the Elementary School counseling center, if they wish to have a voice in the class placement process.
