This international online conference (29–31 January 2026) aims to provide a forum for researchers working on the implementation of the Common European Framework of Reference for Languages (CEFR) and its Companion Volume (CV) (Council of Europe, 2001, 2020) as well as for scholars employing Learner Corpus Research (LCR) to describe learner language at different CEFR levels. Colleagues working on the CEFR/CV and LCR are welcome to share their findings at this international online conference and explore opportunities for future collaboration.
