The Curriculum for Wales’ plurilingual journey: from learning and teaching to assessment? The new 3 to 16-year-old Curriculum for Wales is due to be implemented from 2022 across schools in Wales, UK. The new curriculum discusses a ‘multilingual and plurilingual approach’1 to the delivery of Welsh, English and International Languages. Changes are also being made to 16-year-old qualifications in Wales, although it is not yet clear what such changes may involve for languages qualifications. Therefore, what does the new Curriculum for Wales’ ‘multilingual and plurilingual approach’2 entail for the learning, teaching and assessment of languages across secondary schools in Wales? My PhD explores the above-mentioned question, collating data from language education stakeholders, secondary school practitioners and students using semi-structured interviews and creative focus groups. This presentation aims to discuss preliminary findings from the research relating to multilingualism and assessment across secondary schools in Wales. In this presentation, findings discussed include: a) the local / plurilingual Wales context of assessment; b) the significance of the (non)-alignment of plurilingual teaching and learning with assessment; c) what skills are considered as plurilingual skills to be assessed.
