Which German Exam Is Hardest? Goethe vs telc vs ÖSD vs DTZ
At the same CEFR level, none of these exams tests meaningfully “harder” German — B1 is B1, regardless of which organisation certifies it. What actually differs is access, structure and format, and those differences matter more for how hard an exam feels than the underlying language content does.
The honest starting point
CEFR levels are standardised precisely so that a B1 from Goethe, telc, ÖSD or the DTZ all mean roughly the same competency. None of these organisations sets out to be “harder” than the others at a given level — they’re independently developing tests to the same external standard.
What genuinely varies is: who can register, how the exam is structured, what the pass criteria look like, and how forgiving the format is if you’re strong in some skills and weaker in others.
The four exams, side by side
| Goethe-Zertifikat B1 | telc Deutsch B1 | ÖSD Zertifikat B1 | DTZ | |
|---|---|---|---|---|
| Who administers it | Goethe-Institut | telc GmbH | Austrian ÖSD | telc + Goethe-Institut, for BAMF |
| Can you register without a course? | Yes, no prerequisite | Yes, no prerequisite | Yes, no prerequisite | No — must complete an Integrationskurs first |
| Structure | Fully modular — 4 independent modules | Combined: written block + oral block | 4 skills, structure similar to Goethe/telc | Fixed structure, taken as one sitting |
| Speaking exam length | ~15 min (3 tasks) | ~15 min (3 tasks) + 20 min prep | ~15 min (3 tasks) | ~15–20 min (self-intro, picture description, joint planning) |
| Pass threshold (speaking) | 60/100 for that module alone | 45/75 (60%), independent of written | Broadly similar structure to Goethe | No pass/fail — certified at A2 or B1 depending on performance |
| Outcome if you’re weak in one skill | Retake just that module | Retake the failed component (written or oral) | Similar to Goethe/telc | You’re certified at whichever level (A2 or B1) your performance supports |
Where the real differences are
Access is the biggest practical difference. Goethe, telc and ÖSD can all be booked directly by anyone, at any test centre, with no prerequisite course or certificate. The DTZ cannot — it’s specifically the exit exam for Germany’s state-funded Integrationskurs, and you generally need to complete that course before sitting it. If you’re not enrolled in an Integrationskurs, the DTZ isn’t actually an option for you regardless of your level.
Modular structure changes how “hard” a weak module feels. Goethe’s full modularity means a bad day on Sprechen doesn’t touch your Lesen or Hören results — you retake exactly the part that needs it. telc’s format groups written skills together, so a stumble anywhere in that block affects the combined written score, even if your speaking is fine. For someone strong in three skills and weak in one, Goethe’s structure is meaningfully more forgiving.
The DTZ has no fail state, which changes the psychology of the exam. Every other exam here is pass/fail against a target level. The DTZ instead certifies you at whichever level — A2 or B1 — your actual performance demonstrates. You can’t technically fail it, only end up certified lower than you hoped. Several practical guides note this explicitly and describe the DTZ’s atmosphere as less adversarial as a result — examiners are documented as actively supporting the interaction if a candidate is struggling.
telc’s Sprachbausteine section is a distinct hurdle. telc’s written exam includes a dedicated grammar-in-context section (fixed verb-preposition pairs, case usage, connectors) worth a meaningful share of the written score — a format that doesn’t have a direct equivalent in Goethe’s written modules. Candidates who find isolated grammar testing harder than contextual reading may find this section the toughest single piece of the four exams compared here.
Whichever exam fits your situation, the speaking component across all four rewards the same underlying skill: producing German out loud, under mild pressure, in response to something unscripted. SipLingo runs real voice conversations, corrects your grammar and word choice in your own language, and scores you on word accuracy, grammar, fluency and intonation. A1 to B2. Try it free →
So which one should you actually take?
If an institution or authority requires a specific certificate — many do, for citizenship, Ausbildung, or nursing recognition — that decision is made for you. Check the exact requirement before choosing anything, since not every accepting body treats all four as interchangeable in practice even though they’re all officially recognised CEFR certifications.
If you’re enrolled in a state-funded Integrationskurs, the DTZ is usually the natural endpoint and often the most cost-effective option, since it’s built into the course.
If you have a choice and want the most forgiving structure, Goethe’s full modularity is worth weighing — particularly if you suspect one skill is meaningfully weaker than the others.
If cost and test-centre availability are the deciding factor, telc tends to have broader international availability and is often priced comparably to or below Goethe, depending on your country.

What doesn’t actually change across exams
The underlying B1 or B2 competency being tested is the same regardless of which logo is on your certificate. Study habits that build genuine speaking ability — regular practice, feedback on real mistakes, comfort with unscripted follow-up questions — transfer completely across all four. None of them rewards a fundamentally different kind of German; they just package the assessment differently.
Cost and scheduling, in practice
Prices vary by country and test centre, but as a rough guide across all three: expect somewhere in the range of €150–250 for a B1 exam, with telc and Goethe generally comparable and the DTZ typically bundled into Integrationskurs fees rather than charged separately. Booking windows also vary — popular test centres in larger cities can fill up several months in advance, so if you have a deadline (a citizenship appointment, a job start date), check availability early rather than assuming you can book close to when you need the result.
Results typically take 4–6 weeks to arrive across all three exams, which is worth building into any timeline where the certificate itself is a hard requirement for something else — a visa application, a citizenship appointment, an Ausbildung start date.

Frequently asked questions
Which German exam is hardest: Goethe, telc, ÖSD or DTZ? None is inherently harder at the same CEFR level — they’re all calibrated to the same external standard. The practical differences are access (the DTZ requires completing an Integrationskurs first; the others don’t), structure (Goethe is fully modular, telc combines written skills into one block), and pass criteria (the DTZ has no fail state, only a lower certified level).
Is telc B1 easier than Goethe B1? Not inherently — both test the same CEFR level. telc groups written skills into a single combined score rather than fully separate modules, which can feel less forgiving if you’re weak in just one written skill. Goethe’s full modularity lets you retake a single weak module in isolation.
Can I take the DTZ without an Integrationskurs? Generally no — the DTZ is specifically designed as the exit exam for the state-funded Integrationskurs and typically requires completing that course first. If you want a B1 certificate without taking a course, Goethe or telc are the accessible options.
Is ÖSD accepted the same as Goethe in Germany? Both are internationally recognised CEFR certifications, but acceptance for a specific purpose — citizenship, a job, a university programme — depends on the requiring institution. Always confirm which certificates a specific authority accepts before assuming they’re interchangeable.
No matter which exam you’re preparing for, the speaking component comes down to the same thing: real practice, out loud, with correction. SipLingo scores you on word accuracy, grammar, fluency and intonation across real conversations. A1 to B2.
