B1 German for citizenship: which certificate counts
Last updated 2026-08-16
German naturalisation asks you to show German at B1 on the CEFR scale. The part that confuses people is that there is no single "citizenship exam" — several different certificates satisfy the same requirement, and which one suits you depends mostly on how you are learning.
This page is not legal or immigration advice. It describes language certificates. Residency periods, eligibility and the rest of a naturalisation application are outside its scope and have changed more than once — check official sources or a qualified lawyer for those.
What B1 means
B1 is the "independent user" threshold — a real step up from A2. At B1 you can handle most situations that come up while living in the country, describe experiences and plans, and give short reasons for an opinion. It is the level at which a language stops being a set of phrases and starts being usable.
The certificates commonly accepted
| Certificate | Awarded by | Usually taken by |
|---|---|---|
| Goethe-Zertifikat B1 | Goethe-Institut | Independent learners; recognised internationally |
| telc Deutsch B1 | telc gGmbH | Widely available through language schools |
| ÖSD Zertifikat B1 | Österreichisches Sprachdiplom | The Austrian equivalent, also recognised |
| DTZ Deutsch-Test für Zuwanderer |
telc / g.a.s.t. | Anyone finishing a state integration course |
The DTZ is the one worth understanding
If you take a state-funded integration course (Integrationskurs), the DTZ is the exam at the end of it — so many people already have their certificate without having chosen it.
The DTZ is scored differently from the others, and this catches people out. It is a single exam with two possible outcomes: everyone who sits it receives a certificate, but it is issued at A2 or B1 depending on the score. So "I passed the DTZ" is not the same statement as "I have B1" — the level printed on the certificate is what matters.
How the exams are structured
All four test the same four skills — reading, listening, writing and speaking — and all four reward familiarity with the format as much as vocabulary. The speaking component in particular is a structured interaction rather than a free conversation, and meeting that structure for the first time on exam day is an avoidable way to lose marks.
Where to check
- Goethe-Institut — the Goethe-Zertifikat exams and dates.
- telc — telc Deutsch and the DTZ.
- BAMF — integration courses and the naturalisation requirements themselves.
Meanwhile
WLE does not yet have German papers — Portuguese is the language written so far, and Deutsch is listed as being written. The self-study guide is written around CIPLE but the argument transfers: format and timing are what solitary preparation reliably misses, in any language.
