Saxony International School – Carl Hahn gGmbH

What Saxony International School – Carl Hahn gGmbH does

Saxony International School – Carl Hahn gGmbH is a non-profit (gemeinnützige GmbH) educational institution headquartered in Glauchau, Saxony, Germany, founded in 2009 and named after industrialist Prof. Dr. Carl H. Hahn. It operates a network of approximately 16 bilingual international schools spanning primary (Grundschule), secondary (Oberschule), and grammar school (Gymnasium / Wirtschaftsgymnasium) levels across more than ten Saxon towns, complemented by 18-22 Kita and after-school (Hort) facilities operated by its strategic partner GGB (Gesellschaft zur ganzheitlichen Bildung gGmbH Sachsen). The schools deliver bilingual German-English instruction with Spanish as an additional foreign language, under a holistic pedagogy of "learning with head, heart, and hand."

The institution's distinctive technical and credentialing infrastructure includes recognition as an official competence center for the European language certificate TELC (The European Language Certificates) and, since 2024, operation of the world's first telc-SIS Academy, a platform for language certification and skilled-worker qualification creating direct educational and career pathways between Egypt and Germany. Additional proprietary features include play-based English instruction in preschool settings (since 1998 via GGB) and interdisciplinary STEM projects such as the Stratosphere Balloon initiative. The network supports Erasmus+ exchanges, the Hotsy Totsy therapy center partnership, and cooperation with Hochschule Zittau/Görlitz for international higher-education and workforce pathways.

Revenue is generated primarily through recurring tuition and school fees paid by families enrolling children in the K-12 pathway, supplemented by professional-services income from TELC certification examinations and telc-SIS Academy offerings. The organization markets through a multilingual website (11 languages), social media, seasonal open houses, and international project visibility. Governance rests with two managing directors, Rüdiger School and Dr. Sabrina Simchen-Schubert, and the institution has no disclosed external investors or parent-company ownership; it operates as an actively running non-profit with multi-year awards (BVMW 2022; Fokus X 2021) and consistent above-Saxon-average performance in state competency tests.

Expansion highlights3 records

Regional players

• Dresden International School: Dresden International School is an IB World School in Saxony with an English-language curriculum, making it a direct regional competitor for international-minded families within SIS's core geography.
• Berlin Brandenburg International School: BBIS is a leading IB school in the Berlin-Brandenburg region offering international K-12 education; while outside Saxony, it competes for some of the same international-family demographic seeking German education.
• Leipzig International School: Leipzig International School is an IB World School in Saxony offering English-language K-12 instruction, competing for the same pool of internationally oriented families in Saxony.

Direct peers

• Phorms Education: Phorms operates a network of bilingual German/English schools and nurseries across multiple German states, closely mirroring SIS's curriculum positioning and full K-12 pathway model, but at a larger national scale.
• St. Thomas More Schools: St. Thomas More operates private German schools with bilingual offerings and an international curriculum orientation, making it a direct comparable for SIS's bilingual private school model.

Broad incumbents

• Frankfurt International School: FIS is one of the largest and oldest international schools in Germany, offering IB programs from early years through grade 12. It is a broader incumbent in the same international-school category as SIS.
• Munich International School: MIS is an established, larger IB international school in Germany offering the full K-12 pathway. It is comparable on curriculum type and target family, but operates at a larger scale in a different metro.

Emerging players

• Carl Duisberg Centren: Carl Duisberg Centren operates German language schools and TELC exam centers across Germany, providing a language-certification and workforce-integration peer comparable to the telc-SIS Academy's positioning.
• GLS Sprachenzentrum: GLS is a major German language school with immersive programs. While focused on adult language instruction rather than K-12, it is relevant as a TELC exam preparation and language-certification peer in the German market.

Others

• Hochschule Zittau/Görlitz: Although a higher education institution rather than a K-12 peer, HSZG is a confirmed SIS partner in internationalization and skilled-worker qualification, and operates in the same Saxony ecosystem with overlapping international-student programs.
