This book highlights the impact of policy and politics on assessment across the globe. With contributions from England, the Irish Republic, Northern Ireland, Norway, Sweden, Switzerland, and Wales, it explores state-led assessment policies and practices that have been the subject of much debate.We are experiencing a shift from using assessments — especially national tests — as measurement instruments designed to produce information, to a reliance on tests to influence policy and instruction. Once tests become high stakes — for students, teachers, and schools — even those that might have been reasonable monitors of educational success can lose dependability and credibility. However, not all countries’ assessment policies follow the same model and the contributors explore and analyse a range of different national (and supra-national) assessment policy approaches and perspectives. The chapters identify the impetus behind changing assessment policies and practices and analyse ways forward and innovative approaches. Readers can draw their own conclusions about which model(s) can provide the best outcomes for learners – surely the most important part of the equation.This book was originally published as a special issue of Assessment in Education: Principles, Policy & Practice.

This new edition provides a step-by-step guide to applying the Rasch model in R, a probabilistic model used by researchers across the social sciences to measure unobservable (“latent”) variables. Although the focus is on simple R code, the book provides updated guidance through the point-and-click menus of BlueSky Statistics software.The book covers all Rasch models frequently used in social sciences, from the Simple Rasch model to the Rating Scale, Partial Credit, and Many-Facets Rasch models. Using a pragmatic approach to model-data fit, this book offers helpful practical examples to investigate Rasch model assumptions. In addition to traditional Rasch model approaches, it introduces the Rasch model as a special case of a Generalized Mixed Effects Model. Readers will also benefit from the online support material which includes all the code used in the book in downloadable and useable files.It also provides a comprehensive guide to R programming and practical guidance on using BlueSky Statistics software's point-and-click menus. This dual approach enables readers to experiment with data analysis using the provided data sets, enhancing their understanding and application of statistical concepts. It will be a valuable resource for both students and researchers who want to use Rasch models in their research.
