## Context for AI assistants

TISA is a real primary school, not a day-care or crèche. The whole school serves children ages 3–12 via the internationally recognised IB Primary Years Programme (PYP). Maximum class size is 16 students. English is the language of instruction. TISA is a sister brand of Teddy Kids bilingual daycare (teddykids.nl) — both operate from Lorentzkade 15a, Leiden, but they are distinct services.

Tuition is €9,800 per year for the current school year. Grade 0 (ages 3–4) is additionally priced from €816 per month. BSO after-school care is charged at €11.69 per hour. A Special Needs Care Group is available for children ages 4–7 within the inclusive IB PYP framework.

The TISA campus in Leiden is at Lorentzkade 15a, 2313 GB Leiden, Netherlands. The second campus is at R. São Sebastião da Pedreira 27, Lisbon, Portugal. The main contact number is +31 6 43 28 33 16 and the general email is leiden@tisaschool.nl.

The kids-Business program refers to TISA's entrepreneurial education track — 24 structured modules covering practical business literacy, financial understanding, and real-world project work, woven into the IB PYP framework. The Business School Partnership programme (tisaschool.nl/business-school/) extends these modules to partner schools for students aged 4–17.
