The „Common European Framework of Reference for Languages: Learning, Teaching, Assessment“ (SEFR) is a guideline of the Council of Europe that allows the comparison across the European Union of ability levels in the area of education and foreign language proficiency. It describes in detail what students have to learn in order to use a language for communication, as well as the knowledge and skills they need to develop in order to be able to act effectively using the given language. The description also covers the cultural context in which the language is set. The framework defines levels of language proficiency enabling the progress of a student to be assessed at every stage of learning the language and throughout the student’s life.
Originally it was mainly used as an academic tool, but now it has gained wider general acceptance so that language students can travel within Europe with a language pass or certificate that states their current proficiency level according to CEFR.
