The Common European Framework of Reference for Languages (CEFR) is a guideline used to describe the proficiency levels of language learners. It provides a standardized way to assess and compare language skills across different languages and countries. The framework is divided into six levels, ranging from A1 (beginner) to C2 (proficient), helping educators and learners understand their language abilities. CEFR is widely used in language education, testing, and curriculum development. It helps institutions create clear learning objectives and assessments, ensuring that students progress effectively. By using CEFR, learners can set realistic goals and track their improvement in language skills over time.
