The language of instruction at ISB is English.  All ISB students are required to study English and a second language – German, French, Spanish, or the student’s mother tongue.

There are three types of language course available within the IB Diploma: Language A, Language B and Language Ab Initio. The courses are designed with the following student profiles in mind:

Type of Course

Student Profile

Language ATypically for students who are already fluent in both reading and writing the target language, and who are experienced in using the language within an academic context.
Language BTypically for students with 2-5 years’ experience of learning and using the target language.
Language Ab InitioTypically for students with little or no previous experience of the target language.


The IB requires students to choose language courses that match their level of experience in the language. Whichever type of language course is chosen, it is expected that the course content should provide the student with a genuine challenge.

The IB requires students to choose at least one Language A. Students for whom English is their second language, are encouraged to study their mother tongue as an A language. The study of two A languages will gain the student a Bilingual IB Diploma.

The underlying principle of students learning two languages is to promote an understanding of other cultures through the study of languages and their literature, and to develop communicative competence.

More details of the language courses on offer at ISB in the IB Diploma can be found in the IB Diploma Subject Guide.
