This paper reports on a design-based implementation study of the use of a diagnostic classroom assessment tool framed on learning trajectories (LTs) for middle grades mathematics, where teachers and students are provided immediate data on students’ progress along LTs. The study answers the question: “How can one characterize the challenges encountered when a school implements a diagnostic assessment system around learning trajectories at scale?” by identifying three explanatory themes: shifting to classroom assessment, understanding the concept and content of the LT, and seeing the results as a call to action. Each theme is discussed with references to observed activities and discussions with participants and related to the challenges connected with taking the concept of LTs to scale.
