The Common European Framework of Reference (CEFR) is a guideline used to describe the levels of language proficiency across different languages. It provides a standardized system to assess and compare language skills, ranging from beginner to advanced levels, categorized as A1, A2, B1, B2, C1, and C2. This framework helps educators, learners, and employers understand language abilities more clearly. Developed by the Council of Europe, the CEFR aims to promote transparency in language education and facilitate communication across cultures. It is widely used in language teaching, assessment, and curriculum development, making it easier for individuals to navigate language learning and certification processes.
