Every Dutch citizen aged 18 and up is obligated to have health insurance. LSBv and ISO, together with Zilveren Kruis Achmea, have set up a health insurance policy especially for students: Studenten Goed Verzekerd. This health insurance policy contains everything that students need and is one of the cheapest in the Netherlands.
