Volume I of the Handbook for Assessment in the Service of Learning offers a theoretical and research-grounded vision for transforming educational assessment into a catalyst for learning. Drawing on contemporary learning sciences, measurement theory, and improvement science, the volume is organized into three sections that offer principled design and conceptual frameworks for integrating assessment with teaching and learning; ground assessment in the social, cultural, and developmental nature of how people learn; and examine how emerging technologies like artificial intelligence might enrich balanced assessment practices while upholding technical requirements of validity: fairness, scientific soundness, utility and creditability. Informed by the vision of the Gordon Commission for the Future of Assessment in Education, this volume explores rethinking assessment as an integral component of pedagogy that informs the processes for learning and its improvement over time rather than just a final evaluation of the status of learning achieved. It provides the foundations for building assessment systems that are human-centered, just, and truly in the service of every learner.
