The Common European Framework of Reference for Languages (CEFR) provides common standards for teaching, learning, and assessing foreign languages across Europe. Published in 2001 by the Council of Europe, the CEFR describes foreign language proficiency at six levels from A1 to C2. It helps teachers set goals, select materials, and evaluate progress. Teachers can use the CEFR's detailed descriptions of language skills and example "can do" statements to guide instruction and help students self-assess. The CEFR also encourages students to reflect on their learning through language portfolios and take ownership of their progress toward communication goals.
