Which B1 Certificate Counts for German Citizenship?
You have decided to naturalize, you know you need B1 German, and now you are staring at a list of exams (Goethe, telc, DTZ, ÖSD) with no idea which one the authorities actually want.
The answer, up front: any exam on the official BAMF list counts. For citizenship they are treated as equal proof of B1. BAMF is the Bundesamt für Migration und Flüchtlinge, the federal migration office that sets the rules. So the real question is not “which one is accepted,” it is “which one fits me.”
What actually counts
The BAMF publishes a list of recognized B1 proofs. If your certificate is on it, it works. The recognized exams are:
- Goethe-Zertifikat B1 (and the Jugendliche version)
- telc Deutsch B1: the whole family (Zertifikat Deutsch, telc B1+ Beruf, B1·B2 Beruf/Pflege, and more)
- DTZ: the Deutsch-Test für Zuwanderer, run by G.A.S.T., at the B1 level
- ÖSD Zertifikat B1 (Austrian) and the Jugendliche version
- DSD I / DSD I PRO (the school-based German Language Diploma)
- ÖIF integration certificates at B1
- ECL Deutsch B1
One thing that trips people up: internal certificates from a university language center or a private school do not count, even if they say “B1” on them. The proof has to come from one of the recognized exams above.
Picking the one that fits you
For most people the realistic choice is between four: Goethe, telc, DTZ, and ÖSD. Here is how they compare.
| Exam | Price (varies by center) | Who runs it | Retakes | Best for |
|---|---|---|---|---|
| DTZ | Free for authorized integration-course participants (roughly €180 if you self-fund) | G.A.S.T. / BAMF | Re-sit the exam | You are in a state-funded integration course, so it doubles as your proof |
| telc Deutsch B1 | ~€155–€240 | telc gGmbH | You can retake single modules | Fastest, cheapest path if you fail just one part |
| Goethe-Zertifikat B1 | ~€165–€270 (Goethe lists €259 external, ~€104 per module) | Goethe‑Institut | Retake single modules | The most widely recognized name, useful abroad too |
| ÖSD Zertifikat B1 | Center-dependent | ÖSD (Austria) | Re-sit | Common if you are studying in Austria or near the border |
Prices move by city and test center, so treat these as ranges, not quotes. A few practical rules of thumb:
- Cheapest, if you qualify: the DTZ, because it is free inside an integration course.
- Fastest recovery from a partial fail: telc or Goethe, because both let you retake only the module you missed instead of the whole exam.
- Most portable: the Goethe certificate. It is the name most recognized outside Germany, if you might need it elsewhere later.
The DTZ scoring rule most sites get wrong
This is the detail worth knowing, because a lot of pages state it incorrectly.
An overall B1 result on the DTZ does not require B1 in all four skills. According to both BAMF and the test provider (G.A.S.T.), you reach an overall B1 when you have B1 in Speaking, plus B1 in at least one of the two other groups: Listening and Reading count together as one group, and Writing is the other.
In plain terms: you can be uneven, strong in speaking and one of the other groups, and still walk away with an overall B1 result that counts for citizenship. If someone told you that you need a clean B1 across every skill on the DTZ, that is not how the scoring works.
Expiry, degrees, and other common questions
A few things get asked constantly, and the real answer to most of them is “ask your local office”:
- Does a B1 certificate expire? There is no legal expiry. Some naturalization offices prefer recent evidence, but that is local practice, not a national rule. Check with your Einbürgerungsbehörde before assuming an old certificate is dead.
- Does a German university degree or TestDaF count? These are not on the BAMF B1 list. People claim they work, but you should not count on it. Confirm with your authority before relying on a degree instead of a B1 exam.
- Does a German school diploma count? A German school-leaving qualification (Hauptschulabschluss or higher) is generally accepted in administrative practice, and it can also exempt you from the citizenship test.
When a rule is not written in black and white, the safe move is a five-minute question to your Einbürgerungsbehörde, not an assumption that costs you an exam fee.
The certificate is not the finish line
This is the part nobody selling you an exam prep course wants to say plainly.
A B1 certificate proves you cleared a bar on one day. It does not prove you can hold the conversation at your citizenship interview, or handle the German that daily life in Germany actually throws at you. The exam is a milestone. Real, usable B1 German is the thing underneath it, and that is what the interview and the years after naturalization actually run on.
So aim past the certificate. Build German you can use, and the exam becomes a formality you pass on the way through.
That is what our B1 German course is built for: not exam tricks, but German that holds up when you need it. If you want the realistic timeline first, we broke it down here: how long it takes to reach B1. And if the citizenship rules themselves are still fuzzy, start with the full 2026 requirements.
