We do not receive any state funding. All profits generated are reinvested in the company and are not distributed. The shareholder of Carl Duisberg Centren is the non-profit foundation "Carl-Duisberg-Stiftung für internationale Bildung und Zusammenarbeit."

Company name

Our company name stems from the "Carl Duisberg Gesellschaft" (CDG) which was founded by German federal and regional authorities in 1949. We see ourselves as a company that follows in the tradition of CDG's commitment to the international qualification of young leaders and executive managers.

The Carl Duisberg Quality Management System

Carl Duisberg Centren is one of the first educational service providers in Germany to have its quality management system audited on an annual basis by an independent institution. Since 1997, the ISO 9001 certificate has been a clear symbol for our continuous conformity with the requirements of this globally recognised quality management model for the company's language courses, language travel and international school programs.
