De Amsterdamse Montessorischool

What De Amsterdamse Montessorischool does

De Amsterdamse Montessorischool (Stichting De Amsterdamse Montessori School, DBA: De AMS) is a Dutch government-funded primary school founded in 1916 by Mej. C.W. Tromp, operating as a stichting (foundation) from two municipal-monument-designated locations in Amsterdam-Zuid: Albrecht Dürerstraat 36 (onderbouw, ages 4-6, in a 1935 W. van Tijen-designed open-air school building) and Willem Witsenstraat 14 (midden- en bovenbouw, ages 6-12, in a 1983 Herman Hertzberger-designed Apolloschool building). The school delivers Montessori-based primary education across three grade groups (onderbouw, middenbouw, bovenbouw; groups 1-8), using authentic Montessori materials (Golden Material, Pink Tower, Brown Stair, self-correcting tools) integrated with the Kosmisch Onderwijs en Opvoeding (KOO) curriculum built on the DaVinci method, the Taaldoenkast language system, and the Fichesspel decimal system. The education model emphasizes self-directed work, mixed-age classrooms, individualized pacing, and observation-based development tracking.

The revenue model rests on three streams: per-student Dutch government education funding (onderwijsbekostiging) as the primary, recurring subscription-style base; voluntary parent contributions (vrijwillige ouderbijdrage) priced on a solidarity/income-tiered basis; and pass-through transaction fees from after-school activities (dance, chess, English lessons, tennis, football, capoeira, musical theater). The go-to-market is direct enrollment via the BOVO (Bovenschools Overleg) lottery for Amsterdam Centrum/Zuid and parent referrals, with no commercial marketing. The school is governed by an independent parent-community board (typically six to eight members) led by a chairperson (Liselore van der Heijden) and operates day-to-day under Director Marjolein Spaargaren. Operational partners include BSO providers (Woest Zuid, KleintjeZuid, Villa Vondel, Compananny), preschool via Combiwel, music via Muziekschool Amsterdam, and municipal swimming via Sloterbad.
