ESCP Business School Berlin e.V.

“The ESCP Business School Berlin e.V. has been working extremely successfully with Carl Duisberg Training Center (CDC) Berlin for several years. CDC conducts numerous language training courses that are integrated into the teaching of our intercultural degree programs. CDC is invaluable in this regard, especially in organizing this offering. Thanks to the wide range of language trainers and a professional online system for determining the language competence of our students, CDC is able to respond excellently to the constantly changing requirements of our organization and our customers.

Particularly noteworthy is the flexibility and unconditional service orientation with which CDC helps us create added value for our customers. More than 60% of the students at our university are not from Germany, while a semester abroad is mandatory for the remaining 40%. As a European business school, we see it as part of our educational mission to challenge and promote European cultural and linguistic diversity within our study programs. CDC is an extremely valuable partner in this regard, without which it would not be possible to offer language training in this diversity and quality locally.

The trainers at CDC are of the highest calibre, and the trainings are always adapted to the performance level and background of our students. The order processing always goes off without a hitch. The CDC always responds to changes and special requests quickly, constructively and extremely professionally. This is confirmed by the consistently positive feedback and the sustained improvement in our customers‘ language skills.”

Globus Baumärkte/Hela Profi Zentrum

“Cooperation with Carl Duisberg Centren / satisfaction in order processing / implementation of language training:
We have been working with Carl Duisberg Centren for many years and conduct language courses for our employees in English, French and, more recently, Chinese.

The employees – from trainees to managers – take up the offer well and continue to develop their skills. We are very satisfied with the cooperation, the communication is very good. The implementation is customer-oriented and flexible.

Trainer quality:
Having listened to the feedback from our employees, the trainers are highly competent – this is due to the fact that they are native speakers – they are very pleasant and friendly during the courses. This contributes to making the training a great deal of fun.

Benefits for the company – sustainability – through language training with Carl Duisberg:
We see the courses offered to our employees not only as an enrichment of their skills for their daily work, but also as a personnel marketing instrument for particularly interested and committed employees. ”

MyoGrad International Research Training Group for Myology

“We have been offering French language training at the Carl Duisburg Training Center since June 2012 to the doctoral students of ‘MyoGrad International Research Training Group for Myology’, who are pursuing a doctorate with binational supervision (German/French) in the field of muscle research.

A course was quickly established here that is tailored to the specific and individual needs of the doctoral students. Qualified native-speakers provide lively French courses for our participants with the help of very varied teaching material; in fact, the language they have learned can be applied to everyday life almost immediately. In addition, regular evaluations allow adjustments to be made during the course.

All in all, the language course at the Carl Duisburg Training Center enables doctoral students who had little or no previous knowledge of French to find their way around the Paris laboratory or everyday life in Paris within a very short time.”

Nestlé Product Technology Centre

“Nestlé maintains a lively exchange with colleagues from all over the world. Thus, foreign colleagues and their families also regularly come to Germany for longer periods. Learning the German language is an essential part of the integration process; the colleagues should be able to move confidently and autonomously in everyday German life. Carl Duisberg Centren has proved to be an ideal learning partner for us and a very good working relationship has developed over the years.

The teachers are competent and adapt very well to the different needs of their "students". Teaching in small groups has proven to be very effective. This also applies to the English courses that Carl Duisberg Centren also holds in our company. English is the language of business at our company, and we want to ensure that our staff constantly expand and improve their knowledge.”

Sibecon GmbH – HR Consulting

“Sibecon GmbH is a human resources consulting company that, among other things, places foreign candidates with German client companies. As part of a project, a Greek specialist with an intermediate knowledge of German received further language training at Carl Duisberg in individual lessons.

From the onset of the initial discussions regarding the course planning, the needs analysis and the program that was tailored to our needs, it was evident that we were dealing with seasoned professionals. The course participant was able to make significant progress within a very short time; he praised the high quality of the teachers and the challenging but varied organization of the lessons.”

VdTÜV The Association of the TÜV e.V.

“The international orientation of our member companies means that we in the TÜV e.V. association have to train our English in order to be able to respond quickly to inquiries.

The language training at Carl Duisberg Centren fully meets the requirements of modern business English. Our trainer is responsive to our specific needs. For example, we have worked with her to develop standard emails in English that directly support us in our daily work.

The other topics are always current and interesting, so that lively group discussions always arise – this is simply the best way to learn. The lessons are never boring, but always varied and even the grammar is taught in a fun way. The joint English lessons also enable communication across departmental boundaries: employees get to know each other better.”
