The Common European Framework of Reference for Languages (CEFR)
The CEFR is a reference text for all professionals in the field of modern languages.
It was conceived in 1997 at the initiative of the Council of Europe to provide a coherent basis, as comprehensive as possible, for the development of language programmes and their evaluation. It defines six increasing levels of language competence from A1 to C2 with three intermediate levels (A2+, B1+ and B2+).
It is supported by a detailed analysis of communication contexts: written comprehension and expression, oral comprehension and expression.
