CLU Leermiddelen Adviescentrum

What CLU Leermiddelen Adviescentrum does

CLU Leermiddelen Adviescentrum (full legal name: Stichting CLU – Centrum voor Leermiddelenadvies) is a Dutch non-profit foundation headquartered in Amersfoort, Netherlands, that develops evidence-informed criteria and instruments for evaluating the quality of educational learning materials (leermiddelen). The organization traces its operating history back 35 years to its origins within Utrecht University and was formally re-established as an independent foundation on May 23, 2023, becoming fully operational on September 1, 2023. Its primary constituents are Dutch schools, school boards, sector councils, and government bodies across primary (PO), secondary (VO), and vocational (MBO) education.

The foundation's core product is MILK (MeetInstrument Leermiddelen Kwaliteit), a scientifically grounded evaluation instrument that assesses learning materials against an evidence-based set of quality criteria. MILK-light is a condensed variant of approximately 60 criteria intended for faster application. CLU also publishes research reports and the CLU Boekenreeks book series, and delivers training and workshops under the Professionalisering banner. Recent content output includes commentary on AI in education, indicating engagement with emerging technology discourse within its domain. The organization contributes to the Landelijk Kwaliteitskader (national quality framework), positioning it as a quasi-regulatory voice in the Dutch learning materials market.

The business model is fee-for-service: CLU does not rely on structural government subsidies, instead generating revenue through commissioned research, advisory and consulting engagements, professional development offerings, and partnerships. Named customers and partners include PO-Raad (primary education council), the Ministry of Education (OCW), VO-content, StudioVO, Alfa-college (vocational/MBO), Kennisnet, Impuls Open Leermateriaal (IOL), and Education Warehouse (with a partnership dating to July 7, 2022 to build an independent evaluation platform). Pricing is not publicly disclosed, and the foundation operates entirely within the Netherlands with no disclosed international expansion.
