What TANDEM International e.V. does
TANDEM International e.V. is a German-Spanish non-profit association (eingetragener Verein) registered in Frankfurt am Main, Germany, founded in 2001 as a federation of independent language schools. It operates as a central coordinating body for a network of 11 member schools located across six German cities (Bremen, Düsseldorf, Frankfurt, Hamburg, Cologne, Munich), four Spanish cities (Barcelona, Granada, Madrid, San Sebastián), and Santiago de Chile. The member schools retain independent ownership and operate under shared quality standards codified by the association's internal TANDEM Gütesiegel (quality seal).
The association's core offering is in-person German and Spanish foreign-language instruction, delivered through intensive, super-intensive, evening, and exam-preparation courses (TestDaF, TELC, DELE, SIELE). Its differentiated methodology is the trademarked TANDEM Sprachaustausch (language exchange), which pairs native speakers of different languages to practice each other's language equally. Member schools hold institutional accreditations from Instituto Cervantes, TestDaF-Institut, and TELC, and participate in EU Erasmus+ teacher-training mobility programmes. Supplementary services include accommodation booking, cultural excursions, city-hopping (multi-city study), and tailor-made group programmes.
The association functions as a coordinating/marketing layer rather than a single operating business: revenue is generated by individual member schools through course fees, accommodation services, group programmes, and teacher training, with pricing varying by school, course type, and intensity. The central association employs approximately 21 staff in a coordinator role, while individual schools operate as independent commercial entities under the unified TANDEM brand.
