Assessment is the new focus for a great many innovative activities. Whether we look at video-based competency assessment, project and team assessment, simulation driven assessment, or new forms of artificial intelligence supported assessment, significant change is happening. This book looks at the underlying issues as well as some of the practical developments, with a strong focus on K-12, with the book intended for those pursuing teacher education. All of this is transferable to post-secondary education. The strength of the book is in the connections between theory and practice, between best practice and innovation.
