Our mission statement

TANDEM International e.V. is an international association of independent language schools that aims to promote cross-cultural awareness and understanding through language learning.

As a member of this umbrella organisation, TANDEM Cologne has been successfully operating as an independent language school in Cologne since 2004. We are proud of our high-quality teaching, the good organisation, the familiar atmosphere and the good and modern equipment of the school.

We are distinguished by the fact that we are constantly facing up to new demands in the field of education and that we are constantly striving to develop further, both organisationally and in terms of content.

What we offer

Our high-quality language services are geared both to the individual needs of our clients and to the requirements of a globalised educational landscape. We prove our competence every day in our German and foreign language courses. In doing so, we strive to always provide our clients with innovative, target group-oriented educational offers and to continuously improve them.

Our quality

As part of our membership in TANDEM International e.V. and in the Qualitätsgemeinschaft Berufliche Bildung Region Köln e.V. (Quality Association for Vocational Education and Training in the Cologne Region), we have committed ourselves to subjecting our services to a continuous process of quality assurance. This is ensured both by evaluating customer surveys and by means of teaching observations. At regular intervals, a quality check is carried out on site by the two institutions mentioned above.

Our quality standards are reflected in the up-to-dateness of the teaching material, in the selection of motivated and qualified teachers, in the modern equipment of the classrooms and in our customer-oriented service.

Our staff

Our staff are competent, committed and identify with the goals of our institution. Both internally and externally, our cooperation is characterised by mutual respect, trust, openness, reliability, responsible action and sensitivity in dealing with each other. The teachers are native speakers and have a lot of teaching experience and excellent professional competence. They enjoy teaching and dealing with people and are happy to pass on their enthusiasm for their language and culture.
Customer orientation

We place special emphasis on offering our clients excellent service, providing them with individual attention and answering enquiries quickly and professionally. TANDEM Cologne offers a wide range of courses and is working on the continuous development of this offer. Fair and transparent participation conditions are a matter of course for us.

Offering innovative services is an important aspect of customer orientation. Thus, TANDEM Köln attaches particular importance to the development of course-accompanying products: personally selected accommodation, course-accompanying cultural programmes, supplementary online language courses as well as preparation for recognised certificates and exams and their implementation form an important complement to the language course.
Ethos, social commitment and sustainability

TANDEM Cologne is characterised by participatory decision-making processes that give staff the opportunity to influence the school's objectives and products.

In addition, we cooperate with social and cultural initiatives and environmental associations. This is done either in the form of donations, by giving preference to solidarity-based institutions when awarding contracts or by actively supporting actions and projects of these institutions. In addition, we make an active contribution to environmental protection by purchasing fair trade products, ecologically sustainable office and teaching materials and environmentally friendly cleaning products.

We recommend our participants from abroad to travel by train or, if travelling by car or plane, to offset their CO2 emissions via https://www.atmosfair.de or https://www.myclimate.org. TANDEM Cologne also supports environmentally friendly travel financially.
