During the past decade, national qualifications frameworks (NQFs) have been developed and implemented across Europe. Triggered by the adoption of the European qualifications framework (EQF) in 2008, these frameworks draw attention to the outcomes of education and training, focusing on what learners are expected to know, understand and are able to do. Learning outcomes-based level descriptors are essential to these frameworks. While technical in their character, these descriptors not only help to define and map the (vertical) level of complexity of a particular qualification, they also help to clarify its (horizontal) orientation, be this on theoretical knowledge, practical skills and/or transversal competences. Level descriptors are thus important reference points, aiming to reinforce the learning outcomes orientation of education, training and qualification systems. This publication provides an updated overview of NQF level descriptors of 39 countries participating in EQF implementation. It celebrates the 10th anniversary of the EQF process in 2018 and its contribution to transparency and comparability of European qualifications. It shows the progress made in this area and challenges ahead.
