Is the DTZ B1 enough for naturalisation and residence permit?

Simply put: yes, DTZ at B1 level is enough for naturalisation

If your Deutsch-Test für Zuwanderer (DTZ) shows B1 as your result, you meet the language requirement for standard naturalisation. Since the 2024 reform of German nationality law, B1 is the standard language level you must demonstrate after five years of residence. A higher level such as B2 or C1 is not required for standard naturalisation.

Residence permits (indefinite right of residence under Section 9 AufenthG) also require B1. Your DTZ certificate can be used for both pathways if it shows B1.

What exactly is the DTZ?

The DTZ is a single exam with two possible results: A2 or B1. You don’t sit “the B1 exam” but rather the DTZ, and depending on your score, your certificate shows either A2 or B1. This is important to understand, because only the B1 result helps you with naturalisation.

The DTZ consists of two parts:

• Written part (approximately 100 minutes): listening, reading, and writing.
• Spoken part (approximately 16 minutes): usually as a paired exam with another test-taker.

All four language skills are tested: listening, reading, writing, and speaking. Important: the written and spoken parts are assessed separately. To achieve an overall B1, you must reach B1 level in both parts. If you only achieve B1 in one part, your certificate shows the lower result.

B1 for naturalisation: what applies today

For standard naturalisation you need:

1. Normally five years of lawful residence in Germany.
2. German language skills at B1 level, for example through the DTZ showing B1 as your result.
3. Passing the naturalisation test (a separate test with 33 questions on society, history, and law).
4. Secured means of subsistence and other requirements.

The DTZ covers only the language requirement. You must sit the naturalisation test separately; it’s a different exam.

Important: there is no more fast-track naturalisation with C1

Until 2025, there was a faster route: naturalisation after just three years if you could demonstrate C1-level German and special integration achievements. This so-called “turbo naturalisation” was abolished in October 2025. The Bundestag and Bundesrat decided that the five-year period with B1 now applies to everyone.

What this means for you in practical terms: a C1 certificate offers no time advantage for naturalisation any more. B1 is and remains the level you need. So save yourself the stress of a harder exam if all you want is a German passport.

B1 for the residence permit

The residence permit under Section 9 AufenthG also requires “sufficient knowledge of the German language”, and that means B1 level. The DTZ showing B1 as your result meets this requirement. Often you’ve already demonstrated B1 through the integration course, which ends with the DTZ.

Note: there are exceptions, for example for illness, disability, or hardship cases. There are also some other residence titles with lower requirements. For the standard residence permit, B1 is the norm.

Which certificates are recognised?

For naturalisation, not only the DTZ counts. All common B1 qualifications are recognised, for example:

• DTZ with B1 result
• telc Deutsch B1
• Goethe Certificate B1
• ÖSD Certificate B1

The DTZ has the advantage of usually being taken at the end of the integration course anyway and being cost-effective. telc and Goethe are useful if you haven’t taken the DTZ or want to retake a single module. With the Goethe Certificate B1, you can even retake the four modules (reading, listening, writing, speaking) individually.

If the DTZ only shows A2

If you only achieve A2 in the DTZ, that does not meet the requirements for naturalisation or residence permit. You then have two options:

• Retake the DTZ, often with a free repeat module from the integration course.
• Take another B1 exam, such as telc B1 or Goethe B1.

In both cases, solid preparation is worthwhile so you’re sure to reach B1 level. If you want to practice specifically for B1, a structured course with a real teacher helps. Our B1 online German course prepares you using the Hueber textbook “Schritte plus Neu” and an AI speaking trainer, with focused practice for pronunciation and letter writing tailored exactly to exams like DTZ, telc, and Goethe. If you still have gaps at A1 or A2, close these first before moving to B1 level.

Conclusion

For standard naturalisation and the residence permit, B1 is the right and sufficient level. The DTZ with B1 as your result is enough; you don’t need an expensive or harder certificate. Just make sure your certificate really shows B1, and remember the additional naturalisation test when you apply. With solid B1 preparation, the path to a German passport is well within reach.
