National Curriculum Tests for Mathematics in English and Welsh: creating matched assessments

This paper aims to add to the growing literature on test translation and parallel development. After providing a brief overview of bilingual education in Wales and national assessment arrangements, the paper goes on to consider the experience gained over recent years in preparing matched mathematics assessments in English and Welsh. Although the paper focuses on the above experience a number of issues are highlighted which should be of interest to readers who may be concerned or involved with cross‐cultural, cross‐linguistic test development elsewhere.
