The ISI Lower School begins with pre-elementary classes for students 3 years old through kindergarten before transitioning to the elementary school years from grades 1 to 5.
Elementary classes for grades 1 to 5 also follow the IB Primary Years Program curriculum and begin taking an even more significant role in directing their own hands-on learning and finding answers to their questions.
Lower School Support Services
school day and classrooms
The Lower School starts classes each morning at 8:15 a.m. and the school day ends each day at 3:00 p.m. Students have morning and lunch recesses.
With nine teachers and nine assistant teachers, the overall student-faculty ratio in pre-elementary classes is 8:1. Pre-elementary classes can vary in size from very small to 16 students.
Pre-elementary classes near the larger end of this enrollment spectrum utilize full-time teaching assistants. Teaching assistants are either native speakers or are perfectly fluent in the target language for their class.
The student-faculty ratio for the elementary grades is also 8:1. Classes can vary in size from very small to 18 students. The average class size is 12-15 students.
To reflect our multicultural spirit, ISI incorporates celebrations from many cultures into our school year. Examples include our bell-ringing ceremony at the start of the new school year (Ukrainian in origin), a formal breakfast in early December (from the Dutch tradition of Kerstontbijt), the French Fête des Rois (a traditional Epiphany celebration in January with a marzipan ‘galette’ or cake), and many others.
Field trips to local points of interest support our pre-elementary curriculum.
Elementary students attend overnight camps and go on field trips that support the elementary curriculum.
