Parents at ISH are very supportive of the school’s mission and philosophy. They regularly attend school functions, and are very keen to be part of school projects in both sections of the school. Parents can be involved via the Parent Teacher Association (PTA) in Primary and the Parents Association (PA) in Secondary. There are also connectors for new parents who come to ISH to help them become acquainted with the school and other parents. Additionally, parents can find out more about the school via the MR (Medezeggenschapsraad) a participation council, where elected representatives of teachers, students and their parents are consulted by the school management over matters concerning the management of the school.
