The Common European Framework of Reference (CEFR) is a document that provides a common basis throughout Europe for the development of programs, exams, textbooks, etc. for learning modern languages. It describes what language learners must learn and what skills they must acquire in order to communicate with people who speak that language.
The CEFR delineates a graduated sequence of common reference levels that allow to accurately describe the competence achieved by those who are learning a language other than the mother tongue. The CEFR levels are 6 and on the one hand the aim is to help the student to identify his own level of competence and on the other hand to make him aware of the skills required to reach the next levels.
