The Common European Framework of Reference for Languages (“CEFR”) is all about the global proficiency scale and the “can do” statements. The global proficiency scale categorises learners as:
To be of value, the common reference levels need objective definitions. This is done by means of positive “can do” descriptors, e.g. a student at level A1 “can
interact in a simple way provided the other person talks slowly”, and “can introduce him/herself and others”. The CEFR “can do” statements are concerned with the
learner’s ability to interact successfully in social situations using the target language. This goes beyond the traditional four skills, because social interaction typically requires different skills to be combined, e.g. a conversation requires both listening and speaking skills. The CEFR statements do not refer to linguistic form, but they do presuppose that the learner has sufficient knowledge of form – including vocabulary, grammar and relevant aspects of the spoken language – to interact in the manner described.
