The International Baccalaureate Secondary section is a multilingual programme with an international student and teacher population. Students work in small groups in an open class setting with several teaching stations. Subjects are presented by one teacher and in one language. Depending on the subjects and topics, follow-up work can be done in English and/or French, thus advancing in the multilingual skills. Simultaneously Dutch, German, Spanish, French and English are present as language advancement subjects. Students choose languages with the help of the MYP coordinator and in line with their language background and experiences.

In the Diploma Programme students choose two languages being Language A and Language B. The other four subjects are predominantly given in the English language, therefore a good command of English is required.
