The Common European Framework of Reference for Languages (CEFR) is a guideline used to describe the proficiency levels of language learners across Europe. It provides a standardized system to assess and compare language skills, ranging from A1 (beginner) to C2 (proficient). This framework helps educators, employers, and learners understand language abilities and set clear learning goals. CEFR is widely used in language education, influencing curriculum design and assessment methods. It supports the development of language teaching materials and promotes a common understanding of language proficiency. Many language exams, such as those for English, French, and German, align their levels with the CEFR.
