BSO Internationale School Leiden

BSO Internationale School Leiden is located on the ground floor of the International School Leiden’s modern campus at Van Vollenhovenkade 15. We provide after-school care for up to 44 children aged 4 to 12 in a bilingual Dutch-English setting. Our professional staff collect the children after school and welcome them with a healthy snack and story time. The afternoon continues with daily outdoor play—garden games, sports, or nature exploration—followed by child-led clubs that change every term: cooking, coding, arts, science experiments and more. During school holidays we transform into a full-day programme packed with themed projects, field trips around Leiden and special guests. We share the building with ISL, ensuring a smooth transition from classroom to after-school fun. Safety, engagement and joyful learning are at the heart of everything we do, and we maintain close communication with parents to make every afternoon an adventure worth talking about at the dinner table.
