introduces pre- and in-service teachers to the foundations, data use, and best practices of the DCA framework. As differentiated instruction practices increasingly enable K-12 educators to individualize learning in their classrooms, it is important that this framework be extended to assessment as well. This concise yet comprehensive book explains the science and rationale behind DCA as well as principles and strategies for both formative and summative assessments. Replete with vignettes, sample outputs, and recommendations, this is a lively and much-needed guide to understanding, enacting, and analyzing grouped and individualized assessments.
