Goethe, telc, TestDaF, ÖSD – the selection is large. But not every course will apply to every visa, every admission or any professional recognition recognized. 800 euros invested, three months time - and then it turns out: You need another proof for your purpose. This can be avoided.
Clear assessment
Language schools sell courses – not orientation. This leads to expensive wrong decisions.
Foundation
All German language certificates are based on this Common European Framework of Reference (CEFR) with six levels. Which level is needed depends on the purpose – Which certificate is accepted depends on the authority or university.
Six levels – very different requirements depending on the goal
To the language level guide| level | Designation | Typical use |
|---|---|---|
| A1 | Elementary language use – introduction | Spousal reunification (certain cases), basic integration |
| A2 | Elementary language use | Naturalization process (basic requirement), some training places |
| B1 | Independent use of language | Naturalization, settlement permit, lots of training |
| B2 | Independent use of language – elevated | Many work visas, professional recognition, university language certificates |
| C1 | Competent use of language | University admission (alternative to TestDaF/DSH), medical professions |
| C2 | Competent use of language – mastery | Rarely required; Teaching degree, highest qualification levels |
Decision support
The question is not: “Which course is good?” – but: "What proof will be accepted for my goal?" Here are the most common constellations.
Almost all German universities require either as proof of language skills TestDaF (at least TDN 4 in all four sections) or DSH level 2 (DSH-2). Goethe certificates are only accepted at very few universities – and only in exceptional cases. Anyone hoping for admission with a Goethe-C1 fails at most universities.
Exception: Some universities also accept telc German C1 University – but this needs to be checked before applying, not after.
There is no nationwide language requirement for dual vocational training. The training company and, if necessary, the immigration authorities decide. In practice it will B1 or B2 expected – and almost every recognized certificate (Goethe, telc, ÖSD) is accepted. Here the level is more important than the provider.
For professional recognition by responsible bodies (IHK, Chamber of Crafts, Medical Association, etc.) Some of their own requirements apply. Medical and nursing professions often require C1, sometimes explicitly Goethe C1 or telc C1 Medicine. For general specialists, B1 or B2 from any recognized provider is often sufficient.
For simple spouse reunification to Germany A1 knowledge the minimum standard – proven by Goethe-A1, telc A1 or ÖSD A1. All three are accepted. Anyone who is already learning B2 here invests in something that is not needed at that time.
For German citizenship B1 demanded. The certificates from common providers are used as proof (Goethe, telc, ÖSD, DTZ) recognized. If you already have another language certificate at a higher level, does not have to take an additional B1 test.
Provider comparison
They are all based on the CEFR - but they are not recognized equally everywhere and have different focuses.
Goethe Institute
A1 A2 B1 B2 C1 C2
The most famous German language certificate in the world. Broad international recognition – but not automatically for all German universities approved as proof of admission to study.
For university admission: only accepted at very few universities.
TestDaF
TDN 3 · TDN 4 · TDN 5
Especially for him University entrance in Germany developed. Is recognized as a language certificate by almost all German universities and technical colleges. Not a level-based system – but sub-area grades.
For non-native speakers only. Minimum requirement usually TDN 4 in all parts.
telc
A1 A2 B1 B2 C1 C2
Wide range of certificates with special variants – e.g. telc German C1 University for university applicants or telc German B2 C1 Medicine for health professions. Wide recognition in authorities and companies.
The special variant “telc C1 Hochschule” is approved at many universities.
Typical mistakes
These mistakes are avoidable – if you know what proof you need before booking the course.
The most common bad investments – and how they happen
Many applicants learn at Goethe-B2 or Goethe-C1 – and determine when applying that the target university only TestDaF or DSH accepted. That means: new learning, new course, new appointment – and at least one lost semester.
Anyone who needs an A1 certificate for spouse reunification and instead If you book a B2 course, you pay more – and wait longer. A1 is enough for the application, B2 can come later. The order decides whether you lose months.
The German language test for university entrance (DSH) is only taken directly at universities – not through external providers. If you want to prepare for this, you have to be in Germany or complete a preparatory course outside. Many applicants don't even know about this option.
Not every language school that issues a certificate is officially accredited testing partner of the respective provider. Only exams that are taken by accredited test centers are recognized. A simple confirmation of participation is not enough.
