Effects of the First Year of a 3-year Intervention in Learning Trajectory-Oriented Formative Assessment on Grades PreK-3 Student Achievement

The goal of this research project was to explore the efficacy of building teacher capacity for learning trajectory-oriented mathematics formative assessment on PreK-3 student learning in a set of urban elementary schools. This study was conducted during one of the most challenging school years in recent history, with schools serving a community that was disproportionately affected by the effects of COVID-19, systemic racism, gun violence, and decades of disinvestment.
