De HBM

What De HBM does

De HBM is a private Dutch secondary school (VMBO-tl / mavo level) located in Heemstede, North Holland, operating under Stichting IRiS, a foundation governing seven Christian secondary schools serving over 7,600 students across the Haarlem, Haarlemmermeer, and Amstelland-Meerlanden regions. Founded in 1993, the school serves approximately 400 Group 8 graduates annually from the Zuid-Kennemerland region with a differentiated pedagogical model — the (t)huiswerkvrije (homework-free) approach launched in 2018/2019 — under which students complete all schoolwork during school hours under teacher supervision, complemented by specialized tracks (Sportmavo, Kunstmavo, Havo Kansklas) and dual-mentor support structures.

The school operates an integrated platform built around its core homework-free methodology, supported by standard Dutch education technology integrations including Magister (student information system), Zermelo (scheduling), CUP (flex-hour sign-up), Qompas (career guidance), and IDdink (book distribution). No proprietary technology is developed in-house. Revenue is generated primarily through Dutch government educational funding (basisbekostiging), supplemented by a voluntary annual parent contribution (vrijwillige ouderbijdrage) set per grade in consultation with the parent council (MR), and small fees tied to specialized programs (Sportmavo sports materials, Kunstmavo art projects). Distribution is regional and community-driven: enrollment flows through the centralized "De Overstap" digital platform for Zuid-Kennemerland, supplemented by open days, trial lessons (proeflessen), and primary school coordination.

The institution is led by Director Karin Tamis with two team leaders (I.M. van Veen, S. Maij), and partners strategically with Eerste Christelijk Lyceum Haarlem (HAVO transfer pathway), Nova College (MBO transition for 28 VMBO schools), ROSA (teacher training consortium of 16 VO schools and 6 Amsterdam training institutions), CJG (youth support coaching), and GGD Kennemerland (youth health services). It holds a Golden School Canteen Award (2021–2022) from the Dutch Nutrition Center and is currently preparing a new Zorg & Welzijn (Care & Welfare) practical program for the upper school years starting in the 2026–2027 academic year.
