Dr. Clemens' research and teaching focuses on improving instruction and intervention for students with reading difficulties in preschool through adolescence. More specifically, his work is aimed at improving teachers' use of assessment data to better understand their students' progress, and to help them align and individualize evidence-based interventions with their students' unique learning needs in order to promote stronger outcomes. Dr. Clemens is also interested in research that seeks to better understand interventions and key practices that are effective for students with the most intensive learning difficulties.
