In this three-day workshop curriculum developers, language test developers, teacher trainers, teachers and other relevant  takeholders will be introduced to the new mediation and pluricultural/plurilingual scales in the recently published Companion Volume to the CEFR. Participants will check to what extent their FL curriculum makes mention of these skills and find references in the curriculum to skills that are comparable. Reference will be made to mediation activities in the classroom as collected and published in the Companion Volume. Possibilities will be explored to develop classroom-based tests that link up with the above-mentioned descriptor scales and with classroom activities in this field.
