Common European Framework of Reference (CEFR)

The Council of Europe’s Common European Framework of Reference for Languages (CEFR) is a series of descriptions of abilities which can be applied to any language. These descriptors can be used to set clear targets for achievements within language learning, to help define language proficiency levels and to interpret language qualifications. It has become accepted as a way of benchmarking language ability not only within Europe but worldwide and plays a central role in language and education policy
