These descriptors are skill levels according to the Common European Framework of Reference for Languages (CEFR) and are used by language learners to measure their competence, skills and ability at speaking, reading, writing and understanding the language. The Framework also provides a common basis for the development of curricula, textbooks and qualification certificates in European language work and enables interlingual comparability.

On this page, you will find statements related to different skill sets, which are helpful in assessing your own language level and thereby finding the right course for you. According to the Common European Framework of Reference for Languages, the language level is divided into six levels from A1 (beginner) to C2 (expert). Similarly, German courses at the GZK are divided by these levels. Respective CEFR exams are available to those who want to make their level official, i.e. for school admissions, university course requirements, employment / au pair as well as family reunions, among others.
