Considerable variation exists across response-to-intervention (RTI) approaches. There is currently insufficient research on outcomes associated with these different RTI approaches to inform decision-making. However, school psychologists who are asked to work within an RTI model need guidance to select an approach that has a high likelihood of leading to optimal student outcomes. This article describes, illustrates, and supports two aspects of the RTI approach used at the Heartland Area Education Agency, from the perspective of a practicing school psychologist. These two aspects include (a) intervention selection that is based on an individualized problem analysis, and (b) the identification of specific instructional needs as a part of the special education eligibility determination process. An analysis of how the Heartland Problem-Solving Model (PSM) was applied to address the needs of a kindergarten student is provided to illustrate these features. Criticisms and challenges associated with the Heartland PSM are noted, along with guidance for future RTI model research and implementation. (Contains 3 figures.)
