This volume takes a framework for validating tests that was developed in language testing, and applies it to an admissions test used for biomedical courses. The framework is used to consider validity in the BioMedical Admissions Test (BMAT). Each chapter focuses on a different aspect of validity and also presents research that has been conducted with the test. By addressing all of the validity aspects identified as important by language testers, this volume presents a comprehensive evaluation of BMAT's validity. The processes of evaluation used in the book also promote a cross-disciplinary approach to assessment research, by demonstrating how effectively language testing frameworks can be used in different educational contexts. The authors of the chapters include Cambridge Assessment staff and medical education experts, from a wide range of subject backgrounds. Psychologists, clinicians, linguists and assessment experts have all contributed to the volume, making it an example of multidisciplinary collaboration.
