Lehrer-Online

What Lehrer-Online does

Lehrer-Online is a German-language digital platform serving teachers in primary, secondary, and vocational education across Germany with curriculum-aligned teaching materials, professional development courses, and digital classroom tools. Operated by parent company Eduversum GmbH and based in Wiesbaden, the platform provides access to over 100,000 teaching materials (Unterrichtsmaterialien), more than 1,000 professional development courses (Fortbildungen), educational news, and a teacher community of over 250,000 members who can share materials via the Tauschbörse exchange forum. The platform is pedagogically advised by Arbeitsgemeinschaft Jugend und Bildung e.V., ensuring alignment with German federal state curricula. Recent product development centers on the Classroom-Manager 2.0 tool, launched in October 2025 in cooperation with partner School to go, which integrates an AI assistant that generates curriculum-aligned lesson drafts from topic prompts, differentiates tasks by learning level, and suggests interactive formats and image materials.

The business model is a freemium structure: basic teaching materials and platform features are available free, while premium membership unlocks additional materials, the Classroom-Manager AI tools, and enhanced organizational features, with monthly or annual billing options. Individual Unterrichtseinheiten and specialized materials are also sold à la carte at 14.99 EUR per unit. The company also generates project-based revenue from government commissions, exemplified by a contract with the Bundesministerium für Gesundheit (Federal Ministry of Health) to develop teaching materials on electronic patient records for health professions education. Distribution operates through a self-service web platform (lehrer-online.de), supplemented by specialized partner portals covering school law (Schulrecht), adolescence education (Pubertät), and trade crafts (Handwerk macht Schule), as well as broad social media presence and an email newsletter for community engagement.

The company is a privately held for-profit entity within the German education publishing sector, with 11-50 employees and a founding date of 2000. The addressable market is limited to the German K-12 and vocational teacher segment, with stated service to the DACH region. Competitive positioning is built on the breadth and pedagogical quality of the content library, the scale of the teacher community, and increasingly on AI-assisted lesson planning capabilities. The platform has received a Bildungsaward recognizing educational innovation, providing mid-weight third-party credibility.
