Response to Intervention
Response to Intervention (RtI) is an early detection, prevention, and support system that attempts to identify and assist struggling students with appropriate levels of intervention. It is a framework for making instructional decisions based on data, and consists of four components:

Students are categorized into three tiers within the RtI framework. According to researchers, the three tiers are as follows:
