The TestDaF, formally Test Deutsch als Fremdsprache, is a well recognised, standardised language test confirming the German proficiency for non-native German speakers.
The test covers listening comprehension, reading comprehension, writing and speaking, and is recognised by German universities as proof of prospective students’ ability. The grades of candidates are marked in terms of three levels, TDN 3 — 5, which correspond to the Common European Framework of Reference for Languages levels B2–C1
