Exceptional leave
In accordance with the Dutch Compulsory Education Act (Leerplichtwet), leave outside of the school holidays is not allowed. Parents must plan holidays and special events during the official school holidays and in accordance with the school calendar. Exceptional leave can be granted only in very significant circumstances.
The local attendance authority(leerplicht) is responsible for parental compliance with the Dutch Compulsory Education Act and works with ISU in upholding the law.If parents decide to take leave withoutpermission, it can mean parents will be contacted by the attendance authorities(leerplicht).This could also lead to legal proceedings and the imposition of a fine.
Contact secondary.admin@isutrecht.nl orprimary.admin@isutrecht.nl should you want to enquire about exceptional leave.
