What does CEFR stand for in relation to language proficiency?

The correct answer is indeed the Common European Framework of Reference for Languages, commonly abbreviated as CEFR. This framework was developed by the Council of Europe to provide a standardized system for measuring and describing language proficiency across diverse languages and cultures.

CEFR establishes clear criteria for various levels of language ability, which helps learners, teachers, and institutions to navigate language learning and assessment. It categorizes proficiency into six levels, ranging from A1 (beginner) to C2 (proficient), facilitating a common understanding of language competence that can be applied internationally. This makes it a valuable tool for language education, curriculum development, and certification, enabling learners to set goals and measure progress effectively.

The other options do not reflect the established designation or purpose of the CEFR. While they may appear plausible, they don't correspond to the recognized framework used in language education and assessment. In summary, the CEFR serves as an important reference for recognizing and comparing language skills globally.
