CEFR Reference level descriptions (language by language)
The Common European Framework of Reference for Languages: Learning, Teaching, Assessment (CEFR) is in principle applicable to any language and does not therefore relate to any specific one.
Reference Level Descriptions have been drawn up for national and regional languages - for authors of textbooks, syllabus designers and language teachers.
They provide detailed descriptions of linguistic content at the different CEFR levels by identifying forms (words, grammar, etc.) at a given level: the mastery corresponds to the communicational, socio-linguistic, formal and other competences defined by the CEFR.
Reference Level Descriptions are produced not by the Council of Europe but by national teams using various approaches.
