Yes — the TELC B1 certificate (Zertifikat Deutsch) is accepted for German citizenship (Einbürgerung) in 2026. It proves B1-level German under the Common European Framework of Reference (CEFR), which is the standard most Ausländerbehörden require.
This guide covers what immigration offices expect, how TELC B1 compares to the integration course exam (DTZ), and the smartest way to prepare.
What German authorities require for Einbürgerung
For naturalisation, you generally need:
- B1 German — spoken and written proof via an accepted certificate
- Permanent residence or an eligible residence title (rules vary by pathway)
- Integration requirements — e.g. Einbürgerungstest, income, no serious criminal record
A TELC B1 certificate satisfies the language requirement the same way as Goethe B1, ÖSD B1, or the Deutsch-Test für Zuwanderer (DTZ) from an integration course.
| Certificate | Accepted for Einbürgerung? | Typical candidate |
|---|---|---|
| TELC B1 (Zertifikat Deutsch) | Yes | Self-study, exam-focused prep |
| Goethe-Zertifikat B1 | Yes | Goethe Institute students |
| DTZ (Integrationskurs end exam) | Yes | BAMF integration course graduates |
| ÖSD B1 | Yes (check local office) | Austria-focused learners |
For certificate validity rules, see our guide on whether TELC B1 expires.
TELC B1 vs. DTZ for citizenship
Both reach B1. The difference is format and availability:
- DTZ — taken at the end of a subsidised Integrationskurs; strong on everyday integration topics
- TELC B1 — independent exam at TELC centres worldwide; compensatory scoring (strong listening can offset weaker writing)
If you already live in Germany and missed an integration course slot, TELC B1 is often the fastest path once you are exam-ready.
How to prepare: free theory, paid written practice
SprachFlow separates learning from exam simulation:
- Free B1 theory — every guide on our TELC B1 hub, this blog, and the Deutsch Quiz costs nothing. Read format breakdowns, grammar checklists, and section strategies without an account.
- Paid written practice — timed mock sections for the Schriftliche Prüfung (reading parts 2–3, Sprachbausteine, listening, writing) require a 3-month pass. Start with a free Leseverstehen Teil 1 trial to test the platform.
Theory first, then drill the written papers under real timers.

FAQ
Is TELC B1 enough for Einbürgerung, or do I need B2?
Standard naturalisation requires B1. Some federal states or special programmes may ask for more — confirm with your local Ausländerbehörde before booking.
Do I need the Leben in Deutschland test as well as TELC B1?
Yes. Language (B1) and the Einbürgerungstest (Leben in Deutschland) are separate requirements.
Can I use TELC B1 if I took the exam outside Germany?
Yes. TELC certificates are issued internationally and are widely recognised by German authorities.
How long should I study before booking the exam?
From solid A2, plan 3–4 months. Already at B1? 4–6 weeks of exam-format practice is realistic. See our preparation timeline.
