The document outlines the Common European Framework of Reference for Languages (CEFR), which defines levels of proficiency for language learners. It describes 6 levels of proficiency - A1 and A2 for basic users, B1 and B2 for independent users, and C1 and C2 for proficient users. Each level is defined by the language skills and competencies that individuals should have, such as the ability to understand and engage in basic conversation at lower levels and comprehend complex texts and discuss abstract concepts at higher levels. The CEFR provides a common basis for describing language learning objectives and testing proficiency across Europe.
