Welcome to the first issue of Assessment Matters. This new journal provides a forum for discussing, debating and communicating developments and advances in matters relating to assessment in the field of education. It invites researchers, practitioners and policy makers to “push the thinking” in assessment. The goal is to advance our understanding of the science of assessment, recognise the art that accompanies it, and acknowledge the craftsmanship that makes it contextually relevant and meaningful. The frequently used expression “fit for purpose assessment” captures, but also disguises, the complexities and intricacies of realising effective assessment.
