TestDaF Preparation Timeline: How to Reach TDN 4×4

Most German-taught programs need TestDaF 4×4, DSH-2 or telc C1 Hochschule. Plan backwards from your deadline and prepare with AI feedback on writing and speaking.

Key facts

• Most German-taught programs require TestDaF level TDN 4 in all four sections ("4×4"), or an equivalent such as DSH-2 or telc C1 Hochschule.
• The four sections are Reading, Listening, Writing and Speaking; levels are reported as TDN 3–5. The certificate does not expire.
• Recommended preparation is roughly B2–C1 German (about 700–1000 hours of study).
• Plan backwards from your application deadline so your certificate is ready before uni-assist.
• TestDaF is offered several times a year at licensed test centers worldwide, and increasingly as a digital exam alongside the traditional paper format.
• TestDaF and DSH are both accepted by German universities, but DSH is usually sat in Germany at the university itself, while TestDaF is available at test centers in your home country — useful if you would rather not travel before enrolling.
• TestDaF/DSH/telc C1 Hochschule are specifically for German-taught programs; if your program is taught in English instead, universities ask for an English test (IELTS/TOEFL) rather than TestDaF.
• Fees vary by country and test center, and the growing digital format has expanded availability in cities that previously had no in-person test center — check the official TestDaF-Institut site for your nearest current location and exact fee.

Frequently asked questions

What TestDaF score do I need for a German university?

Most German-taught programs require TestDaF TDN 4 in all four sections (written as 4×4), or an equivalent such as DSH-2 or telc C1 Hochschule. A few competitive programs — particularly in fields like Medicine, Law, or oversubscribed Master's programs — ask for TDN 5 in one or more sections, so always check your target program's specific requirement rather than assuming 4×4 is universal. Some programs will conditionally admit you with a slightly lower profile (e.g. TDN 4 in three sections and TDN 3 in one) if your overall academic profile is otherwise strong, though this is at the university's discretion and not something to plan around. Because TestDaF results are valid indefinitely, there's no downside to sitting it earlier and well above the minimum if your schedule allows — a stronger score is a straightforward, quantifiable way to strengthen a borderline application, unlike other parts of the file which are harder to improve on short notice.

What are the four sections of the TestDaF?

TestDaF has four sections: Reading (Leseverstehen), Listening (Hörverstehen), Writing (Schriftlicher Ausdruck) and Speaking (Mündlicher Ausdruck). Each section is scored independently on the TDN scale (TDN 3, 4 or 5), so your certificate shows a distinct level per skill rather than one combined score — this matters because some programs have per-section minimums rather than just an overall average. Reading and Listening are multiple-choice/short-answer format testing comprehension of academic-style texts and lectures; Writing asks you to describe a chart or graphic and argue a position in an essay; Speaking (in the digital format) has you respond to a series of recorded prompts covering everyday and academic situations. Most programs require TDN 4 in all four (4×4), meaning a genuinely weak section can't be offset by strong results elsewhere — practice each section individually rather than assuming general German fluency will carry every part equally.

Is TestDaF harder than DSH?

They test similar language levels (roughly B2–C1), but the format differs in ways that matter for how you prepare. DSH is set and graded by the individual university, so difficulty, topics, and grading style can vary meaningfully by institution — some students find their particular university's DSH noticeably harder or easier than TestDaF, depending on that university's specific standards. TestDaF, by contrast, is centrally standardized by the TestDaF-Institut, so every sitting anywhere in the world is scored against the same benchmark, making your result directly comparable regardless of where you took it. A practical implication: if you're only applying to one university and can find past DSH papers or prep material specific to it, DSH prep can be very targeted; if you're applying to multiple universities or want a portable, universally recognized result, TestDaF is generally the safer choice.

Can I use IELTS or TOEFL instead of TestDaF?

Only if your program is taught in English. TestDaF, DSH and telc C1 Hochschule certify German proficiency and are specifically what German-taught programs require; IELTS and TOEFL certify English proficiency and are what English-taught programs ask for instead — the two certificate types are not interchangeable regardless of how fluent you are in the other language. Check your specific program's language of instruction before deciding which test to prepare for, since some German universities offer the same subject in both a German-taught and an English-taught track with different admission requirements, and it's easy to accidentally prepare for the wrong one. If a program is taught in German but has some English-taught elective modules, you'll still need the German-language certificate for admission — the presence of some English content doesn't change the core language requirement.

Where can I take the TestDaF, and is a digital version available?

TestDaF is offered several times a year at licensed test centers worldwide, and a growing number of locations now offer a digital format alongside the traditional paper-based exam — the digital option has expanded availability to cities that previously had no in-person test center at all. Both formats are scored on the same TDN 3–5 scale and carry equal recognition with universities, so the choice mostly comes down to which is available near you and which testing experience you prefer. Fees vary by country and test center, and available dates fill up faster in cities with fewer sessions, so check the official TestDaF-Institut website for your nearest current center, exact fee, and upcoming dates rather than relying on older information.

Does a TestDaF certificate expire?

No — unlike some language certificates, your TestDaF result does not expire and remains valid indefinitely for university applications. This means there's no disadvantage to sitting the exam earlier in your preparation timeline rather than waiting until the last possible moment, and if you already hold a strong TestDaF result from a previous application cycle, you can generally reuse it for a new application without retaking the exam. That said, some individual universities or specific programs occasionally set their own recency preference as an internal policy (uncommon, but worth a quick check), so confirm with your target university if your result is several years old rather than assuming every program treats it identically to a brand-new certificate.
