The Common European Framework of Reference for Languages (CEFR) is a guideline used to describe language proficiency levels. It helps learners, teachers, and employers understand a person's language skills in a standardized way. The framework divides language ability into six levels, from A1 (beginner) to C2 (proficient), making it easier to assess and compare language competencies across different languages and countries. CEFR is widely used in language education and testing, influencing curricula and certification exams. It provides a clear structure for setting learning goals and measuring progress, benefiting both students and educators in their language learning journey.
