  • Supporting Students Through Response to Intervention : Response to intervention (RTI) is a multi-level prevention system to maximize student achievement and reduce behavioral problems. With RTI, schools use data to identify students at risk of poor learning outcomes, monitor student progress, provide and adjust evidence-based interventions when needed, and identify students with learning disabilities or other disabilities. In this video, Dia Jackson describes the importance of implementing RTI with fidelity and how she provides RTI coaching and professional development to schools so that they see gains in student achievement.
