Validity: Theoretical Development and Integrated Arguments provides a comprehensive examination of the development and application of validity in language testing and assessment. The authors trace major theoretical developments in validity in the UK and the US and examine how validity can be supported through principled test design, test development, and systematic validation. The book argues that evaluating test quality should extend beyond traditional psychometric evidence to include consequences, stakeholder perspectives, and evidence gathered throughout the testing process. It introduces an integrated argument-based approach to validation, emphasizing how different sources of evidence can be combined to support convincing claims about the quality and use of assessment. The book also considers impact by design, localisation, communication with stakeholders, and case studies that illustrate how validity arguments can be developed in specific testing contexts. It is valuable for researchers, assessment professionals, and language testing practitioners.
