The A1 Key is a language proficiency test designed by the Cambridge Assessment English. It assesses basic English skills for beginners. This level is part of the Common European Framework of Reference for Languages (CEFR) and focuses on simple communication in everyday situations. Candidates at the A1 level can understand and use familiar expressions and phrases. They can introduce themselves and ask basic questions about personal details, such as where they live and people they know. The A1 Key is often the first step for learners aiming to improve their English language skills.
