The evaluation of the exam takes place centrally at the TestDaF Institute in Bochum and takes about 6 weeks. The test results of each part of the examination (reading comprehension, listening comprehension, written expression and oral expression) are shown on three TestDaF levels (TDN 3, 4 and 5). If the result is below TDN 3 , the exam is considered failed. In this case you have to repeat all parts of the exam. The test is passed if you have reached at least the TDN 3 level. TDN 4 in all partial skills is usually sufficient to prove sufficient language skills for studying at a German university. TDN 5 is the highest level. The TestDaF levels correspond to the competency levels B2 – C1 in the Common European Framework of Reference for Languages (GER). A detailed description of the levels (TDN) for each part of the exam can be found here.
