Why German Language Tests Matter for PhD Applications


Before answering this question, let's briefly explain why some students prefer to study for a PhD in the German language. There are several advantages associated with this decision, including a strong connection to local academic communities, low-cost programs, seamless and straightforward integration into daily life, and a more favorable job market.


Considering these merits will help explain why many applicants are interested in studying the German language. When applying for a PhD in Germany, you need to demonstrate your proficiency in German at the program or institution you choose.


Many doctoral programs, particularly in engineering, the natural sciences, and STEM fields, are offered in English. In these cases, an IELTS or TOEFL certificate is usually sufficient. But this is the case for English-based courses.


Generally, programs in the humanities, social sciences, education, and law often require strong German skills, as lectures, seminars, and research resources are primarily in German. Plus, it's crucial to be involved in research networks and academic groups, which are mostly communicated in the German language.


Moreover, lacking German language skills can negatively impact your future career in these fields and make communication more challenging with the local community. Even if you are choosing to study in English, it’s better to have a certified level of German or even basic knowledge of it for a better daily life.


Proficiency in the German language will be advantageous when handling administrative tasks, collaborating with peers, or participating in research groups where German is the primary language of communication.


Offering a valid German language certificate shows your ability to collaborate fully and more effectively in academic life. Moreover, it increases your chance of acceptance and strengthens your profile, making you a desirable candidate when competing for scholarships, research grants, or teaching positions during your doctorate.


Commonly Accepted German Language Tests for PhD Admission


German universities usually demand an exam as part of the application process. There are several standardized exams as valid proof of language proficiency.


Test NameMin. Score for PhD AdmissionDifficultyComponents TestedTest Location
TestDaFLevel 4 (TDN 4) in all 4 parts (reading, listening, writing, speaking)Medium–HighReading, Listening, Writing, SpeakingWorldwide (including outside Germany)
DSHDSH-2 (equivalent to B2–C1) required by most universitiesHighWritten exam + oral examOnly in Germany
Goethe-Zertifikat C2C2 (native-like proficiency)Very High (Advanced)Reading, Listening, Writing, SpeakingWorldwide (Goethe-Institut centers)
telc C1 HochschuleC1 level requiredMedium–HighReading, Listening, Writing, SpeakingWorldwide (limited centers)



Each of these exams evaluates reading, writing, listening, and speaking skills but differs in structure, availability, and scoring. It’s better to check each one first and then choose the right one based on your program needs, location, and academic goals. Let’s explore each of these exams in depth and examine their differences.


TestDaF Test

Among the various options, TestDaF is one of the most popular and accessible tests among various possibilities when applying for German-based universities for international students. If you are looking for a valid and standardized test specifically designed for academic purposes, this is an ideal choice for you. You can easily find authentic materials and practices to ensure the test results are perfect and match your needs and preferences.


Like many other proficiency exams, TestDaF also evaluates all four core language skills needed for academic success and social communication.  You have plenty of time to book for the test as it's conducted up to six times a year, making scheduling easier for applicants abroad.


DSH Test

The DSH language exam is exclusively designed and offered by German universities. Note that this test is often taken after a conditional admission offer from universities, so make sure you are on the right track with the institutions before taking on the test. Like the previous exam, DSH also includes a comprehensive written exam and an oral interview, allowing you to practice both receptive and expressive language skills.


A critical issue with the DSH test is that it’s only available in Germany, which may be less practical for applicants living abroad. If you are not based in Germany, this may not be the ideal choice for you. However, it might be sensible if you are already a student in Germany, looking to apply for a higher degree.


Goethe-Zertifikat C2 Test


The most native-based German language test for students is the Goethe-Zertifikat C2. This is a well-known exam that demonstrates the highest level of German language certification and proficiency. If you are looking for a widely respected and exceptional validation of your German language ability, this is the test for you. Your academic and professional future is guaranteed with the Goethe-Zertifikat German test, and fortunately, it is recognized by virtually all institutions.


Telc Test

Telc Deutsch C1 Hochschule was designed for academic admissions and focuses on university-relevant German and enjoys official recognition by German higher education authorities.

Preparation Tips for Success


Getting ready for a German language test is a time-consuming process, requiring your full attention and dedication. It's not something to be done overnight; you need to have a proper plan with realistic expectations, monumental patience, consistency, and a deliberate approach. The first crucial step is to gather all official and authentic practice materials confirmed and produced by the exam providers themselves. 


You can easily prepare for the actual tests with these published materials; for instance, both TestDaF and Telc provide excellent sample exams from previous tests to guide students on how to get ready and know their weaknesses and strengths. Most helpful information, such as the style of exam, the format of questions, and timing conditions, is available. 


If you are serious, working through these resources while applying a straightforward approach of practicing is the key to success and making sure that there are no surprises on test day.


Before registering for any test, it's essential to check each university's requirements. Just having a German language certificate isn’t enough; you need to offer the exact degree for your desired program or institution. Although most universities in Germany accept multiple certifications, some may have strict preferences.

Common Mistakes to Avoid


Although you shouldn't make a big deal of these German proficiency tests, underestimating the level of difficulty of these exams is a frequent mistake among test-takers. A common mistake to avoid when learning the German language is to focus mainly and disproportionately on reading and writing. Unlike the English language, where speaking and listening are relatively straightforward, German requires more time to learn and master these skills.


Many candidates mistakenly consider writing and speaking to be the most essential skills and neglect the speaking and listening practices. This is not the case as these skills carry equal weight in most German language tests, and ignoring them can significantly affect your final score and also make everyday life challenging. 


Another widespread error is overlooking the precise requirements of the intended university and failing to check the exact language needs of the PhD program. Since not all universities recognize and accept duplicate certificates, make sure that you are preparing for the right exam. Learning a new and challenging language like German is a time-consuming process; you don't want to waste your time and money by practicing for the wrong exam. Always confirm which tests are officially recognized by your institution before registering for them.


Plus, procrastination is also a major mistake among candidates. Language acquisition takes time and much practice. The earlier you start, the higher your chance of passing the exam sooner and better. Don't wait until the last month and begin as soon as you can.

Final Thoughts


The most essential step in studying for a PhD in Germany is choosing the language of the program. If you are planning to study in English, an IELTS or TOEFL score is enough, but for German-taught programs, your journey is a bit more difficult and requires more time.  The German language test for a PhD in Germany totally depends on your program, goals, and circumstances, as well as your budget. Besides, you need to take your time and aptitude into account when choosing a German PhD program. 


If you are an international student applying from abroad, the TestDaF is often the most practical option, as there are plenty of practice materials and authentic tests. Thanks to its global availability and unlimited sources, it's easier to prepare for this test, and you can actually plan with explicit instructions and an approach to the exams.  


Regardless of which path you choose, preparing thoroughly and comprehensively is essential in German language tests. Note that you not only need the language for academic and career success, but also that it dramatically affects your future life quality and social stability in Germany. If you are serious about your decision, start today by understanding test formats, confirming program requirements, and planning your exam schedule well in advance. This can save time, reduce stress, and improve your chances of admission.
