Common European Framework of Reference for Languages
One of the aims of the Common European Framework is to describe the levels of proficiency required by existing standards, tests and examinations in order to facilitate comparisons between different systems of qualifications. For this purpose the Common Reference Levels have been developed. The table below summarises the set of proposed Common Reference Levels in single holistic paragraphs and provides teachers and curriculum planners with orientation points.
