Response to Intervention (RTI) models have substantial promise for screening, intervention service delivery, and to serve as catalysts for system change to enhance the educational outcomes of children. RTI represents a more flexible service delivery model; however, it is essential to articulate how RTI can be effectively implemented and demonstrated to be functionally meaningful. This article provides a brief review of probable advantages and possible challenges of implementing RTI and also provides an overview of data emerging from the Screening to Enhance Equitable Placement (STEEP) problem-solving model. Further research is necessary to clearly delineate the purpose(s), operationalize procedures and judgments, and evaluate the decision-making utility of the RTI models in practice. (Contains 2 tables.)
