B1 German for Naturalization – Language Requirements 2026

Language is the fundamental link for social integration. Therefore, German law requires proof of sufficient written and spoken German skills for naturalization (§ 10 paragraph 1 sentence 1 No. 6 StAG). The minimum standard is the B1 level of the Common European Framework of Reference for Languages (CEFR). This standard ensures that new citizens can communicate independently in daily life, work, and contact with authorities.

The B1 level describes independent language use. This means the speaker can understand the main points of clear standard input on familiar matters regularly encountered in work, school, or leisure. One can deal with most situations likely to arise while travelling in an area where the language is spoken, produce simple connected text on topics which are familiar, and briefly give reasons and explanations for opinions.

The standard and most common proof for B1 level is the "Deutsch-Test für Zuwanderer" (DTZ), typically taken at the end of an integration course. The DTZ is a scaled exam covering language levels A2 and B1. It consists of a written exam (listening, reading, writing) lasting about 100 minutes and an oral pair exam of around 15 minutes. To obtain the B1 certificate, the B1 level must be achieved in the oral part and in at least one of the written parts.

As an alternative to the DTZ, other B1 certificates from recognized institutions like telc GmbH or the Goethe-Institut are accepted. It is important that the certificate is valid at the time of application and that the test was completed at a certified testing center. Simple course attendance certificates without an official final exam are not accepted under any circumstances.

However, there are significant simplifications for certain groups. Anyone with a German school-leaving certificate (e.g., Hauptschule, Realschule, or Abitur) does not need to take a separate language test, as their language level is proven by their graduation certificate. The same applies to individuals who have successfully completed vocational training in Germany or a degree at a German-speaking university.

A historic special rule applies since the recent reforms to members of the Gastarbeiter generation (immigrants who entered West or East Germany before 1990). For this group, the legislature lowered the hurdles: they no longer need to complete a written B1 test. Proof of simple oral communication in German in daily life is sufficient (§ 10 paragraph 4a StAG). This is a late recognition of their life achievements.

For all other applicants who must take the language test, targeted preparation is recommended. In addition to language courses at community colleges, online simulators (such as the B1 grammar and reading test on PassKlar) offer an excellent way to assess your level and identify weaknesses. Free writing of emails or letters and grammar in the written part often cause difficulties.

If the B1 level is missed by a small margin, the test can be retaken as often as needed. In many cases, it is advisable to train the specific sub-areas that led to the failure. Since test dates are often booked out, this step of the naturalization process should be planned well in advance.
