General Model of Service Delivery for School-Based Interventions
Substantial research has been devoted to various models of intervention delivery within school systems. Multi-tiered systems of support (MTSS) is an educational service-delivery model in which all students are provided academic and behavioral supports that are matched to need and skill level. A key feature of MTSS frameworks is the ongoing use of data to inform treatment (i.e., intervention) decisions of increasing intensity. That is, MTSS frameworks are tiered models that provide universal (Tier I), secondary (Tier II), and tertiary (Tier III) supports that are explicitly matched to student need. Students’ responsiveness to interventions are then monitored in determining whether students require alternative supports of differing intensity. MTSS, in which intervention intensity is increased dependent on failure to respond to interventions of lesser intensity, has been found to be an effective intervention delivery model. The chapter describes the implementation of MTSS, including specific applications within a Positive Behavioral Interventions and Supports (PBIS) model and Response to Intervention model. Finally, the chapter presents a general data-based problem-solving model that can be utilized to evaluate intervention effect across all levels of support.
