Children aged 12 to 18 who do not speak Dutch will be placed in an international bridge class, called the Internationale Schakelklas (ISK). The ISK offers full-time education, with the main goal of preparing students to transition into regular Dutch-speaking classes.
In Amstelveen, there are two ISK schools:
Futuris for children aged 12 to 16 years old. It is not possible for a child to enroll at this school if they have already been living in the Netherlands for more than two years.
Nova College for children aged 16 and over.
Annebet van Mameren from New2NL made a nice video to explain the Dutch secondary school system, please see the video below.
