Language support for students not fluent in English

English is the main language of instruction and communication at ISB. It is therefore important that all students become proficient in the academic language of the classroom. ISB offers an ELD programme (English Language Development) to enable students to acquire the level of literacy in English needed to access the curriculum in all subjects. An assessment is done upon entry and students will then receive the appropriate ELD programme (Intensive, Intermediate and Advanced). Ongoing assessments allow students to move between levels as their English language skills improve.

Additional language classes offered by the school

French, Dutch, Spanish, Japanese.
In addition to the above languages, ISB is offering an expanded range of languages as part of the home language programme after school. The home language programme is designed to support students in maintaining the language and culture of their home country.
Students taking the IBDP have an option to take their native language as a Tutored Language. There are up to 13 Tutored Languages on offer.

Does the school employ teaching assistants?

Use of technology in the classroom

Every child, from age 3 to 18, is provided with access to age appropriate technology. In the Early Childhood Centre, this means digital cameras, educational games and tablet computers are available for use in every classroom.
From grades 3 to 5, students are engaged directly in one to one computing, meaning every student has their own tablet computer for use in the classroom, integrating technology and research skills into the curriculum to complement all units of study.
Students in grades six and above are given their own laptops. These are used in class and at home, bridging the gap between home and classroom ensuring students can be independent in their learning which can occur at any time and in any place.

Is the school ready to use virtual classrooms when needed? (e.g. teaching lessons online if the school is closed, e.g. during COVID-19 closures)

Currently, it is being used for students needing to quarantine and will be implemented if a lockdown is once again required. Students experience both synchronous and asynchronous learning opportunities.
