Stichting Kalisto Boeiend Basisonderwijs!

What Stichting Kalisto Boeiend Basisonderwijs! does

Stichting Kalisto Boeiend Basisonderwijs! is a Dutch non-profit foundation (stichting) that operates a network of 16 primary schools across the municipalities of Woerden, Montfoort, Stichtse Vecht, and De Ronde Venen, enrolling more than 3,700 students and employing over 375 staff, including 320 teachers. The portfolio comprises 15 regular primary schools (basisonderwijs) plus one specialized basic education school, SBO De Keerkring in Woerden, supplemented by a Day a Week School enrichment program for highly gifted students (hosted at De Regenboog and De Willibrordus) and a Passend Onderwijs (inclusive education) framework across the network. Each school retains its own identity and local character under a shared educational vision emphasizing contemporary teaching, talent development, and Catholic/ecumenical values of love, respect, equality, solidarity, and trust.

The foundation is funded primarily by the Dutch Ministry of Education through per-student allocations, with secondary, non-mandatory voluntary parent contributions at certain schools. Its technology stack centers on the Social Schools platform for unified parent communication and information sharing across all 16 schools, supplemented by digital learning tools, media literacy programs, and other modern educational technologies supporting 21st-century skills. Internal capability development is anchored by the Kalisto Academie, which includes a certified two-year TOP-leerkracht (TOP teacher) program, while operational support is delivered through a Bestuursbureau (executive office) in Woerden covering policy, HR, controller, secretariat, ICT, and cross-school training coordination.

Governance follows the Governancecode Funderend Onderwijs, with a two-person College van Bestuur (Theo Hooghiemstra as Chair and Iris Berkhout as Member), a three-person Raad van Toezicht chaired by Max Hoefeijzers, and a Gemeenschappelijke Medezeggenschapsraad. The foundation holds ANBI (Algemeen Nut Beogende Instelling) status (RSIN 807571982), is GDPR/AVG compliant, and publishes annual reports dating back to 2016. Distribution is entirely regional: parents enroll directly at their preferred school, with no digital/online education delivery model and no geographic expansion beyond the four founding municipalities.
