Berlin International School

What Berlin International School does

Berlin International School (BIS), operated by the non-profit Private Kant-Schulen gGmbH, is a private bilingual international school in Berlin-Dahlem, Germany, serving approximately 996 students from over 70 nationalities across kindergarten, primary (grades 1–5), secondary (grades 6–10), and the IB Diploma Programme (grades 11–12). The school's core product is an International Baccalaureate curriculum: the IB Primary Years Programme (PYP) and IB Middle Years Programme (MYP) combined with the Berlin Rahmenlehrplan, leading to the IB Diploma plus the German MSA (Mittlerer Schulabschluss) qualification. Instruction is delivered bilingually in German and English by native speakers, supported by an EdTech-equipped campus (iPads, Smartboards, Multimedia labs) housed in the historic Haus Dahlem building and the parent organization's KANT-Schul-Forum facilities.

Revenue is generated almost entirely through annual tuition fees billed monthly, tiered by grade: EUR 12,300/year (grades 1–6), EUR 13,560/year (grades 7–10), and EUR 18,240/year (grades 11–12), plus a one-time EUR 800 admission fee and modest resource fees. Customer segments are international and local families in Berlin — most prominently expatriates, diplomats, and corporate-relocation households who value an internationally portable IB diploma alongside German state qualifications. Go-to-market is sales-led via an online admissions process (OpenApply), assisted by an admissions officer, education fairs, and the school's bilingual website; the school holds CIS re-accreditation (2018) and reports strong academic outcomes — 98% IBDP pass rate and 35 average IBDP points in 2025.

Founded in 1997 at the request of the Berlin Senate in response to the Bonn-to-Berlin government relocation, BIS has grown from 12 teachers and 20 students to nearly 1,000 students over 25 years. The school is part of the broader Private Kant-Schulen network (which also includes Kant-Kindergarten, Kant-Grundschule, Kant-Oberschule, and Internationale Schule Berlin) and is governed by managing directors Daniela Mahmoud and Kathleen Wasmuth under school director Michael Cunningham, with founder Horst W. Seidel and his wife Erika Seidel remaining involved via the Stiftung Private Kant-Schulen.
