HSK explained: preparing each level of the Chinese exam
The six HSK levels, the three real difficulties of Mandarin (tones, characters, production) and a level-by-level preparation method.
Read articleThe real differences between the Goethe-Zertifikat, TELC, ÖSD and TestDaF, and how to choose the certification that matches your application rather than your preference.

Once the German level is reached, one question comes up every time: which exam should you sit? Goethe-Zertifikat, TELC, ÖSD, TestDaF, ZERTIFIKAT — the acronyms look alike and the official sites are not explicit about the differences. This guide clarifies what separates them and, above all, how to choose according to your plan.
Before comparing exams, ask the question the other way round: what exactly does the body you will hand the certificate to require? A university, a chamber of trades, a consulate or an employer each has its own list of accepted certifications.
Sitting the wrong exam, even with an excellent result, means starting again. So check the written requirement before committing to a preparation course — it is the most profitable advice in this article.
Awarded by the Goethe-Institut, this is the most widely recognised German certification internationally. It runs from A1 to C2 and tests all four skills: listening, reading, writing and speaking.
The Goethe-Zertifikat is accepted in the vast majority of procedures: family reunification (A1), Ausbildung (often B1), studies (B2 or C1). When an application simply mentions “a recognised German certificate” without further detail, the Goethe is the safest choice.
TELC (The European Language Certificates) also offers exams from A1 to C2, with sector-specific variants — notably TELC Deutsch B1·B2 Pflege for care professions, in high demand among candidates for skilled immigration to Germany.
TELC is widely accepted in Germany, particularly in administrative and professional procedures. Its recognition outside Europe is sometimes patchier than the Goethe’s.
The ÖSD (Österreichisches Sprachdiplom Deutsch) is the Austrian certification. It covers the same A1–C2 scale and tests standard German, with sensitivity to Austrian variants.
If your plan is aimed at Austria, the ÖSD is the natural choice. For a German plan, check that it appears on your contact’s list of accepted certifications — it often does, but not always.
The TestDaF is a different kind of exam: it does not certify a CEFR level in the classic sense, but assigns “TestDaF levels” (TDN 3, 4, 5) in each of the four skills. It is aimed specifically at entry to higher education in Germany.
A TDN 4 across all four skills corresponds, in practice, to the threshold German universities generally expect. If your plan is academic, this is the exam to look at first — but it is more demanding than a Goethe B2 and assumes a genuine academic level of language.
Not sure which exam matches your application? Describe your plan to an adviser: the certification is chosen from the destination.
A common mistake is to carry on with general classes until the day before the test. In fact an exam is prepared on three distinct fronts.
Each paper has its structure: number of parts, question types, timing of each section. A candidate discovering the format on the day loses marks mechanically, regardless of their real level.
This is the most underestimated factor. In written expression particularly, knowing how many minutes to give to planning, writing and checking changes the result.
Examiners assess against a grid: coherence, range of vocabulary, grammatical accuracy, pronunciation. Knowing these criteria lets you work on what earns marks rather than what feels reassuring.
No, unless there is a specific reason. A candidate who needs a B1 and prepares a B2 “to be safe” adds months to the calendar and increases the cost. It is better to obtain the required level with a good score than to narrowly fail a higher one.
The one exception: if you know your plan may evolve — from an Ausbildung towards studies, say — anticipating can make sense.
Count, in order: reaching the level, then preparing the format, then sitting the paper, then receiving the result, then submitting the application. Each of these steps takes time, and exam sessions are not daily.
Build the calendar backwards from your application deadline, not forwards from today. That is the method that avoids nasty surprises.
Goethe for the widest recognition, TELC for administrative procedures and vocational routes, ÖSD for an Austrian plan, TestDaF for higher education in Germany. In every case, start from the written requirement of your destination.
