The Common European Framework of Reference for Languages (CEFR) is an international framework used to describe language ability. German courses and language assessments often refer to six levels: A1, A2, B1, B2, C1, and C2. The levels describe what a learner can typically do with a language, rather than simply how many grammar rules or vocabulary items they have studied.
The levels are grouped into three broad categories. Basic User (A1–A2) covers simple communication and familiar everyday situations. Independent User (B1–B2) describes increasing independence in understanding and communicating. Proficient User (C1–C2) covers advanced, flexible language use and the ability to handle demanding material. These categories are a guide; actual skills can vary between listening, reading, speaking, and writing.
If you are new to German, A1 is usually the natural starting point. If you have studied before, consider your ability to understand spoken German, read texts, write, and speak—not just your memory of grammar. You can then explore the relevant A1 course, A2 course, B1 course, B2 course, C1 course, or C2 course.
