    CEFR spectrum

The CEFR spectrum



This graphical representation of the CEFR is designed to help those who are not language professionals (such as parents, employers, public administrators, etc) gain an overview of the complex structure of the CEFR at a glance. This spectrum, based on that of natural light, illustrates that there are no distinct boundaries between levels but that they flow into one another. The two axes of the graph illustrate the two fundamental, distinct sets of descriptors: qualitative and quantitative. It also shows how the levels are related and how new ones might be inserted. It has no zero point and no end point. It further allows organisations to add their own scales in parallel: for example, below the horizontal axis, the quantitative one, to illustrate how many hours teaching it takes on average to reach a given level.
