Joanna Williamson

My background is in maths and I completed an MMath at the University of Oxford and a PhD in Mathematics Education at the University of Southampton. My doctoral research looked at numerical development in five year olds, specifically, changes in their representations of natural number structures. Before joining Cambridge Assessment in 2015, I worked on statistical research in other areas of education and in healthcare.

I’m part of the Educational Measurement team within the Assessment Research and Development division and the majority of projects I work on involve statistical analyses of assessment data, including the National Pupil Database. In current projects I’m looking at the impact of AS and A Level reform, the effects of mark scheme differences, and relationships between students’ school qualifications and their progression to further/higher education, employment, and training.

Outside of work I spend my time rowing, running and cycling.

Statistical moderation of school-based assessment in GCSEs

Williamson, J. (2016). Statistical moderation of school-based assessment in GCSEs. Research Matters: A Cambridge Assessment publication, 22, 30-36.

Moderation of school-based assessment (SBA), such as coursework, is required in order to ensure the comparability of marks across different centres. Under current procedures for GCSEs, moderators re-mark a sample of SBA from each centre in order to check whether any adjustment should be made to that centre’s marks. This article explores statistical moderation, an alternative form of moderation that calibrates SBA marks on the basis of a statistical relationship with another assessment, such as an exam component. The article outlines methods of statistical moderation that are used in jurisdictions around the world, and explores the effect of applying these methods to results data from three GCSEs. The analysis focuses on comparing the statistically moderated results to operational results (moderated under existing, non-statistical procedures) in terms of marks, grades, and the rank-order of candidates and centres.
